CVE-2024-23771:
NixOS vulnerability analysis and mitigation
Overview
CVE-2024-23771 is a security vulnerability affecting darkhttpd versions before 1.15. The vulnerability stems from the use of strcmp function for authentication verification, which is not constant-time in nature (CVE-MITRE, Debian-Tracker).
Technical details
The vulnerability exists in the authentication mechanism of darkhttpd where the strcmp function is used to verify authentication credentials. The non-constant time nature of strcmp makes it susceptible to timing side-channel attacks, potentially allowing attackers to gather information about the authentication process (GitHub-Commit).
Impact
The vulnerability makes it easier for remote attackers to bypass authentication through timing side-channel attacks, potentially gaining unauthorized access to protected resources (CVE-MITRE).
Mitigation and workarounds
The vulnerability has been fixed in darkhttpd version 1.15 by implementing a new password_equal() function that avoids leaking the length of the secret through timing side-channels. Users are advised to upgrade to this version (GitHub-Compare).
