tag_summary = "POSH is prone to a local file-include vulnerability and a cross-site
scripting vulnerability because it fails to properly sanitize user-
supplied input.

An attacker can exploit the local file-include vulnerability using
directory-traversal strings to view and execute local files within
the context of the webserver process. Information harvested may aid
in further attacks.

The attacker may leverage the cross-site scripting issue to execute
arbitrary script code in the browser of an unsuspecting user in the
context of the affected site. This may let the attacker steal cookie-
based authentication credentials and launch other attacks.

Versions prior to POSH 3.1.2 are vulnerable.";
