List of CVEs: CVE-2016-6601, CVE-2016-6602
This module abuses two vulnerabilities in WebNMS Framework Server 5.2 to extract all user credentials. The first vulnerability is an unauthenticated file download in the FetchFile servlet, which is used to download the file containing the user credentials. The second vulnerability is that the passwords in the file are obfuscated with a very weak algorithm which can be easily reversed. This module has been tested with WebNMS Framework Server 5.2 and 5.2 SP1 on Windows and Linux.
Module Ranking and Traits
Module Ranking:
- normal: The exploit is otherwise reliable, but depends on a specific version and can't (or doesn't) reliably autodetect. More information about ranking can be found here.
