RHEL 6 : squid (Unpatched Vulnerability)

critical Nessus Plugin ID 198515

Synopsis

The remote Red Hat 6 host is affected by multiple vulnerabilities that will not be patched.

Description

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

- squid: improper access restriction upon Digest Authentication nonce replay could lead to remote code execution (CVE-2020-11945)

- squid: Buffer overflow in reverse-proxy configurations (CVE-2020-8450)

- Squid, when transparent interception mode is enabled, uses the HTTP Host header to determine the remote endpoint, which allows remote attackers to bypass access controls for Flash, Java, Silverlight, and probably other technologies, and possibly communicate with restricted intranet sites, via a crafted web page that causes a client to send HTTP requests with a modified Host header. (CVE-2009-0801)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

Solution

The vendor has acknowledged the vulnerabilities but no solution has been provided. Refer to the vendor for remediation guidance.
