Python vulnerability analysis and mitigation

Overview

In lm-sys/fastchat Release v0.2.36, a vulnerability was discovered where the server fails to handle excessive characters appended to the end of multipart boundaries. This vulnerability was assigned CVE-2024-10907 and was disclosed on March 20, 2025. The vulnerability affects the FastChat server implementation (NVD).

Technical details

The vulnerability stems from improper handling of multipart boundaries in the server implementation. When malformed multipart requests are sent with arbitrary characters at the end of the boundary, each extra character is processed in an infinite loop. The vulnerability has been assigned a CVSS v3.0 base score of 7.5 (HIGH) with the vector string CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H. The weakness has been classified as CWE-400 (Uncontrolled Resource Consumption) (NVD, Huntr).

Impact

The vulnerability leads to excessive resource consumption and can result in a complete denial of service (DoS) for all users. The impact is particularly severe as it affects the server's availability without requiring any user authentication or interaction (NVD).
