CVE-2024-8939 Information

Description

A vulnerability was found in the ilab model serve component where improper handling of the best_of parameter in the vllm JSON web API can lead to a Denial of Service (DoS). The API used for LLM-based sentence or chat completion accepts a best_of parameter to return the best completion from several options. When this parameter is set to a large value the API does not handle timeouts or resource exhaustion properly allowing an attacker to cause a DoS by consuming excessive system resources. This leads to the API becoming unresponsive preventing legitimate users from accessing the service.
