Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of mod_auth_mellon installed on the remote host is prior to 0.14.0-8. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2020-1436 advisory.

mod_auth_mellon through 0.14.2 has an Open Redirect via the login?ReturnTo= substring, as demonstrated by omitting the // after http: in the target URL. (CVE-2019-13038)

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 mod_auth_mellon' to update your system.
