Squid Unsupported Version Detection

critical Nessus Plugin ID 57750
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote host contains an unsupported version of a caching proxy server.


According to its self-reported version number, the installation of Squid running on the remote host is no longer supported.

Lack of support implies that no new security patches for the product will be released by the vendor. As a result, it is likely to contain security vulnerabilities.


Upgrade to a version of Squid that is currently supported.
