Vulnerability from fkie_nvd - Published: 2005-05-02 04:00 - Updated: 2025-04-03 01:03
Severity ?
Summary
Squid 2.5, when processing the configuration file, parses empty Access Control Lists (ACLs), including proxy_auth ACLs without defined auth schemes, in a way that effectively removes arguments, which could allow remote attackers to bypass intended ACLs if the administrator ignores the parser warnings.
