Squid Permissions Privileges and Access Controls Vulnerability - CVE-2012-2213

Medium
Reference: CVE-2012-2213
NVD Link: https://nvd.nist.gov/vuln/detail/CVE-2012-2213
Title: Squid Permissions Privileges and Access Controls Vulnerability
Overview:

DISPUTED Squid 3.1.9 allows remote attackers to bypass the access configuration for the CONNECT method by providing an arbitrary allowed hostname in the Host HTTP header. NOTE: this issue might not be reproducible because the researcher is unable to provide a squid.conf file for a vulnerable system and the observed behavior is consistent with a squid.conf file that was (perhaps inadvertently) designed to allow access based on a quotreq_header Hostquot acl regex that matches www.uol.com.br.
