Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

The version of mod24_auth_mellon installed on the remote host is prior to 0.14.0-2.10. It is, therefore, affected by a vulnerability as referenced in the ALAS-2023-1765 advisory.

A flaw was found in mod_auth_mellon where it does not sanitize logout URLs properly. This issue could be used by an attacker to facilitate phishing attacks by tricking users into visiting a trusted web application URL that redirects to an external and potentially malicious server. The highest threat from this liability is to confidentiality and integrity. (CVE-2021-3639)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update mod24_auth_mellon' to update your system.
