CVE-2016-10003 [HIGH] CVE-2016-10003 squid: Information disclosure in Collapsed forwarding
CVE-2016-10003 squid: Information disclosure in Collapsed forwarding
Due to incorrect comparsion of request headers Squid can deliver responses containing private data to clients it should not have reached.
This problem allows a remote attacker to discover private and sensitive information about another clients browsing session. Potentially including credentials which allow access to further sensitive resources.
This problem only affects Squid configured to use the Collapsed Forwarding feature. It is of particular importance for HTTPS reverse-proxy sites with Collapsed Forwarding.
