A flaw was found in squid. The Cache Manager for Squid has rules that, by default, block access to anyone other than the maintainer. An attacker, with the ability to send a properly crafted URL, can bypass the url_regex check and gain access to the blocked resource. The highest threat from this vulnerability is to data confidentiality.
