Description

The version of squid installed on the remote host is prior to 4.14-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2SQUID4-2023-005 advisory.

A flaw was found in squid. Due to improper validation while parsing the request URI, squid is vulnerable to HTTP request smuggling. This issue could allow a trusted client to perform an HTTP request smuggling attack and access services otherwise forbidden by squid. The highest threat from this vulnerability is to data confidentiality. (CVE-2020-25097)
