NewStart CGSL CORE 5.04 / MAIN 5.04 : mod_auth_mellon Multiple Vulnerabilities (NS-SA-2019-0077)

high Nessus Plugin ID 127286

Synopsis

The remote machine is affected by multiple vulnerabilities.

Description

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has mod_auth_mellon packages installed that are affected by multiple vulnerabilities:

- A vulnerability was found in mod_auth_mellon before v0.14.2. An open redirect in the logout URL allows requests with backslashes to pass through by assuming that it is a relative URL, while the browsers silently convert backslash characters into forward slashes treating them as an absolute URL. This mismatch allows an attacker to bypass the redirect URL validation logic in apr_uri_parse function. (CVE-2019-3877)

- A vulnerability was found in mod_auth_mellon. If Apache is configured as a reverse proxy and mod_auth_mellon is configured to only let through authenticated users (with the require valid-user directive), adding special HTTP headers that are normally used to start the special SAML ECP (non-browser based) can be used to bypass authentication. (CVE-2019-3878)

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

Solution

Upgrade the vulnerable CGSL mod_auth_mellon packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
