Synopsis

Squid < 6.4 Remote Code Execution

Description

According to its self-reported version number,the version of Squidcinstalled on the remote host is 5.x < 5.0.4 or prior to 4.13. It is, therefore, affected by a heap buffer overflow and possible remote code execution attack when processing URN.

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Squid version 6.4 or later.
