Squid 5.x < 5.0.4 Multiple Vulnerabilities

high Web App Scanning Plugin ID 112687

Synopsis

Squid 5.x < 5.0.4 Multiple Vulnerabilities

Description

According to its self-reported version number, the version of Squid installed on the remote host is 5.x < 5.0.4 or prior to 4.13. It is, therefore, affected by multiple vulnerabilities:

- Due to incorrect data validation Squid is vulnerable to HTTP request splitting and HTTP request smuggling attacks against HTTP and HTTPS traffic. This leads to cache poisoning. (CVE-2020-15810 / CVE-2020-15811)

- Due to improper input validation Squid is vulnerable to a denial of service attack against the machine operating Squid. (CVE-2020-24606) 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 5.0.4 or later.
