Vulnerability Name:

CVE-2005-0194 (CCN-20323)

Assigned:2005-04-29
Published:2005-04-29
Updated:2016-10-18
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.
