CVE-2004-0189

Squid <2.5STABLE4 - Auth Bypass

Title source: llm
STIX 2.1

Description

The "%xx" URL decoding function in Squid 2.5STABLE4 and earlier allows remote attackers to bypass url_regex ACLs via a URL with a NULL ("%00") character, which causes Squid to use only a portion of the requested URL when comparing it against the access control lists.
