Synopsis

The remote proxy server is affected by a cache poisoning vulnerability.

Description

According to its banner, the version of Squid running on the remote host is 3.x after 3.2.0.11 and prior to 3.5.18, or 4.x prior to 4.0.10. It is, therefore, affected by a cache poisoning vulnerability in the handling of HTTP requests.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Squid version 3.5.18 or 4.0.10 or later. Alternatively, apply the vendor-supplied patch.
