CVE-2012-2213: Medium severity squid web proxy cache vulnerability
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 "reqheader Host" acl regex that matches www.uol.com.br.
