VulnerabilityCVE-2024-10907cvecve-2024-10907cwe-835
Published: Thu Mar 20 2025 (03/20/2025, 10:10:13 UTC)
Source: CVE Database V5
Vendor/Project: lm-sys
Product: lm-sys/fastchat

Description

In lm-sys/fastchat Release v0.2.36, the server fails to handle excessive characters appended to the end of multipart boundaries. This flaw can be exploited by sending malformed multipart requests with arbitrary characters at the end of the boundary. Each extra character is processed in an infinite loop, leading to excessive resource consumption and a complete denial of service (DoS) for all users. The vulnerability is unauthenticated, meaning no user login or interaction is required for an attacker to exploit this issue.
