GHSA-2C3G-G985-WQV4

Vulnerability from github – Published: 2025-08-08 21:30 – Updated: 2025-08-08 21:30

Details

Simple Web Server 2.2 rc2 contains a stack-based buffer overflow vulnerability in its handling of the Connection HTTP header. When a remote attacker sends an overly long string in this header, the server uses vsprintf() without proper bounds checking, leading to a buffer overflow on the stack. This flaw allows remote attackers to execute arbitrary code with the privileges of the web server process. The vulnerability is triggered before authentication.

Severity ?

9.3 (Critical)
