Debian DLA-3359-1 : libapache2-mod-auth-mellon - LTS security update

medium Nessus Plugin ID 172487

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 10 host has a package installed that is affected by multiple vulnerabilities as referenced in the dla-3359 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)

- 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)

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

Solution

Upgrade the libapache2-mod-auth-mellon packages.

For Debian 10 buster, these problems have been fixed in version 0.14.2-1+deb10u1.
