    CVE-2005-0194

    Published: 2 May 2005Last Modified: 10 Apr 2026

    Summary:

    Details: 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.
