CVE-2012-2213

Publication date 28 April 2012

Last updated 24 July 2024

Ubuntu priority

Low

Why this priority?

** 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 "req_header Host" acl regex that matches www.uol.com.br.

Need to check, see reproducer in original post

sbeattie

dropping to low, as it requires a specific configuration using Host header filtering also, upstream does not have a fix for this.

seth-arnold

still unable to find a configuration that could demonstrate the problem; as of 2013-01-28, no fix from upstream either.

Disputed, so ignored.
