Summary
Sliver has DNS C2 OTP Bypass that Allows Unauthenticated Session Flooding and Denial of Service
Details

Summary

The DNS C2 listener accepts unauthenticated TOTP bootstrap messages and allocates server-side DNS sessions without validating OTP values, even when EnforceOTP is enabled. Because sessions are stored without a cleanup/expiry path in this flow, an unauthenticated remote actor can repeatedly create sessions and drive memory exhaustion.

Vulnerable Component

  • server/c2/dns.go:84-90 (EnforceOTP stored but not enforced in bootstrap)
  • server/c2/dns.go:378-390 (TOTP requests routed directly to bootstrap)
  • server/c2/dns.go:490-521 (handleHello allocates session without OTP validation)
  • server/c2/dns.go:495 (sessions.Store with no lifecycle control in this path)
  • client/command/jobs/dns.go:46-52 (operator-facing EnforceOTP control implies auth gate)
  • implant/sliver/transports/dnsclient/dnsclient.go:896-900 (otpMsg sends TOTP with ID=0)
  • protobuf/dnspb/dns.proto:22 (documents TOTP in ID field)

Attack Vector

  • Network-accessible DNS listener
  • No authentication required
  • Low-complexity repeated DNS query loop
  • Trigger path: DNSMessageType_TOTP bootstrap handling

Proof of Concept

Preconditions

  • DNS listener is reachable
  • DNS C2 job is active

Reproduction Steps

  1. Send repeated DNS queries with a minimal protobuf message of type TOTP.
  2. Observe repeated session allocation/issuance behavior.
  3. Continue requests to increase active in-memory session state.

Example

while true; do
  dig +short @<DNS_C2_IP> baa8.<parent-domain> A >/dev/null
done

baa8 is a base32 payload for a minimal TOTP-type protobuf message.

Observable Indicators

  • Repeated bootstrap/session-allocation log entries from handleHello
  • Rising memory usage in the Sliver server process
  • Service slowdown or instability under sustained request volume

Impact

  • Unauthenticated remote denial of service (availability)
  • Resource exhaustion through unbounded session growth in DNS bootstrap path
  • Estimated CVSS v3.1: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H (7.5 High)

Summary
Langflow: Unauthenticated file upload leads to DoS (space exhaustion) and information leak
Details

Summary

Unauthenticated users can upload any amount of data to the server without any limitations. No need for any prior knowledge, only network access to Langflow.

This can lead to space exhaustion on the server.

In adition, in the response, the absolute path of the uploaded file is reported to the attacker, which is an information leak that can assist in chaining other primitives.

Tested on commit 2d67402b1dbaefcbce85a244d4a6cd5e4bda1cfe

Details

Code is in langflow/api/v1/[endpoints.py](http://endpoints.py/):

@router.post(
    "/upload/{flow_id}",
    status_code=HTTPStatus.CREATED,
    deprecated=True,
)
async def create_upload_file(
    file: UploadFile,
    flow_id: UUID,
) -> UploadFileResponse:
...

As can be seen above, there is no authentication. There is not validation over flow_id as well, unlike other endpoints:

        flow_id_str = str(flow_id)
        file_path = await asyncio.to_thread(save_uploaded_file, file, folder_name=flow_id_str)

Function save_uploaded_file saves the file to local file-system. Suggested fix: 1. Add authentication to route. 2. Only return relative path or filename.

PoC

PoC:

curl 'http://localhost:7860/api/v1/upload/<any_uuid>' -F "file=@<any_file>"

Example:

# curl 'http://localhost:7860/api/v1/upload/11111111-1111-1111-1111-111111111111' -F "file=@/tmp/dummy.txt"
{"flowId":"11111111-1111-1111-1111-111111111111","file_path":"/Users/ori/Library/Caches/langflow/11111111-1111-1111-1111-111111111111/9d63c3b5b7623d1fa3dc7fd1547313b9546c6d0fbbb6773a420613b7a17995c8.txt"}

Impact

  1. Space exhaustion on server that can lead to Denial-of-Service.
  2. Information leak - leakage of absolute path of langflow's cache directory in server.

Patches

Fixed in 1.9.1 via PR #12831. The deprecated POST /api/v1/upload/{flow_id} endpoint now uses the get_flow dependency, requiring an authenticated user and flow ownership (returns 404 for missing or cross-user flows), and enforces the max_file_size_upload limit (HTTP 413) — closing the unauthenticated upload and disk-exhaustion vectors. Upgrade to 1.9.1 or later.

Note: the response still returns the file's absolute path (file_path); after this fix it is only disclosed to the authenticated owner of the flow.

Vulnerability from github – Published: 2022-05-17 03:05 – Updated: 2022-05-17 03:05
VLAI
Details

The "process-execute" and "process-spawn" procedures did not free memory correctly when the execve() call failed, resulting in a memory leak. This could be abused by an attacker to cause resource exhaustion or a denial of service. This affects all releases of CHICKEN up to and including 4.11 (it will be fixed in 4.12 and 5.0, which are not yet released).

Summary
Apache Airflow denial of service vulnerability
Details

Apache Airflow, in versions prior to 2.7.0, contains a security vulnerability that can be exploited by an authenticated user possessing Connection edit privileges. This vulnerability allows the user to access connection information and exploit the test connection feature by sending many requests, leading to a denial of service (DoS) condition on the server. Furthermore, malicious actors can leverage this vulnerability to establish harmful connections with the server.

Users of Apache Airflow are strongly advised to upgrade to version 2.7.0 or newer to mitigate the risk associated with this vulnerability. Additionally, administrators are encouraged to review and adjust user permissions to restrict access to sensitive functionalities, reducing the attack surface.

Mitigation
Architecture and Design

Design throttling mechanisms into the system architecture. The best protection is to limit the amount of resources that an unauthorized user can cause to be expended. A strong authentication and access control model will help prevent such attacks from occurring in the first place. The login application should be protected against DoS attacks as much as possible. Limiting the database access, perhaps by caching result sets, can help minimize the resources expended. To further limit the potential for a DoS attack, consider tracking the rate of requests received from users and blocking requests that exceed a defined rate threshold.

Mitigation
Architecture and Design
  • Mitigation of resource exhaustion attacks requires that the target system either:
  • The first of these solutions is an issue in itself though, since it may allow attackers to prevent the use of the system by a particular valid user. If the attacker impersonates the valid user, they may be able to prevent the user from accessing the server in question.
  • The second solution is simply difficult to effectively institute -- and even when properly done, it does not provide a full solution. It simply makes the attack require more resources on the part of the attacker.
  • recognizes the attack and denies that user further access for a given amount of time, or
  • uniformly throttles all requests in order to make it more difficult to consume resources more quickly than they can again be freed.
Mitigation
Architecture and Design

Ensure that protocols have specific limits of scale placed on them.

Mitigation
Implementation

Ensure that all failures in resource allocation place the system into a safe posture.

CAPEC-147: XML Ping of the Death

An attacker initiates a resource depletion attack where a large number of small XML messages are delivered at a sufficiently rapid rate to cause a denial of service or crash of the target. Transactions such as repetitive SOAP transactions can deplete resources faster than a simple flooding attack because of the additional resources used by the SOAP protocol and the resources necessary to process SOAP messages. The transactions used are immaterial as long as they cause resource utilization on the target. In other words, this is a normal flooding attack augmented by using messages that will require extra processing on the target.

CAPEC-227: Sustained Client Engagement

An adversary attempts to deny legitimate users access to a resource by continually engaging a specific resource in an attempt to keep the resource tied up as long as possible. The adversary's primary goal is not to crash or flood the target, which would alert defenders; rather it is to repeatedly perform actions or abuse algorithmic flaws such that a given resource is tied up and not available to a legitimate user. By carefully crafting a requests that keep the resource engaged through what is seemingly benign requests, legitimate users are limited or completely denied access to the resource.

CAPEC-492: Regular Expression Exponential Blowup

An adversary may execute an attack on a program that uses a poor Regular Expression(Regex) implementation by choosing input that results in an extreme situation for the Regex. A typical extreme situation operates at exponential time compared to the input size. This is due to most implementations using a Nondeterministic Finite Automaton(NFA) state machine to be built by the Regex algorithm since NFA allows backtracking and thus more complex regular expressions.
