Description Mark J. Cox 2004-03-11 10:33:32 UTC

A bug was found in the processing of %-encoded characters in a URL in
versions of Squid 2.5.STABLE4 and earlier.  If a Squid configuration
uses Access Control Lists (ACLs), a remote attacker could create URLs
that would not be correctly tested against Squid's ACLs, potentially
allowing clients to access prohibited URLs.
