GHSA-PC8G-78PF-4XRP

Vulnerability from github – Published: 2026-03-02 18:49 – Updated: 2026-03-05 22:49
VLAI
Summary
OliveTin has Unauthenticated Denial of Service via Memory Exhaustion in PasswordHash API Endpoint
Details

Summary

The PasswordHash API endpoint allows unauthenticated users to trigger excessive memory allocation by sending concurrent password hashing requests. By issuing multiple parallel requests, an attacker can exhaust available container memory, leading to service degradation or complete denial of service (DoS).

The issue occurs because the endpoint performs computationally and memory-intensive hashing operations without request throttling, authentication requirements, or resource limits.

Details

The vulnerable endpoint:

POST /api/olivetin.api.v1.OliveTinApiService/PasswordHash

accepts a JSON body containing a password field and returns a computed password hash.

Each request triggers a memory-intensive hashing operation. When multiple concurrent requests are sent, memory consumption increases significantly. There are no safeguards such as:

  • Authentication requirements
  • Rate limiting
  • Request throttling
  • Memory usage caps per request
  • Concurrency controls

As a result, an attacker can repeatedly invoke the endpoint in parallel, causing excessive RAM allocation inside the container.

In a test environment, 50 concurrent requests resulted in approximately 3.2 GB of memory usage (≈64 MB per request), leading to service instability.

This behavior allows unauthenticated attackers to perform a denial of service attack by exhausting server memory resources.

PoC

Environment

  • Docker container: olivetin-test
  • Exposed API on: http://localhost:1337
  • Default configuration (no authentication enabled)

Reproduction Steps

Run the following script to send 50 concurrent requests:

for i in $(seq 1 50); do
  curl -s -X POST http://localhost:1337/api/olivetin.api.v1.OliveTinApiService/PasswordHash \
    -H "Content-Type: application/json" \
    -d "{\"password\":\"flood-$i\"}" &
done
docker stats olivetin-test --no-stream
wait

┌──(root㉿kali)-[~/cve/OliveTin]
└─# docker stats olivetin-test --no-stream
CONTAINER ID   NAME            CPU %     MEM USAGE / LIMIT     MEM %     NET I/O         BLOCK I/O        PIDS
18509670bf3e   olivetin-test   344.63%   6.189GiB / 7.753GiB   79.83%    313kB / 288kB   4.31MB / 106MB   7

Docker CPU is 344.63%

Impact

This vulnerability allows unauthenticated remote attackers to:

  • Exhaust server memory
  • Crash the service
  • Cause availability loss
  • Trigger container termination in orchestrated environments

This is a Denial of Service (DoS) vulnerability affecting service availability.

Production deployments without reverse proxy rate limiting (e.g., Nginx, Traefik) are especially at risk.

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.
