Summary

  * A vulnerability in the web interface of Cisco Network Analysis Module
    Software could allow an unauthenticated, remote attacker to delete
    arbitrary files from an affected system.

    The vulnerability exists because the affected software does not perform
    proper input validation of HTTP requests that it receives and the software
    does not apply role-based access controls (RBACs) to requested HTTP URLs.
    An attacker could exploit this vulnerability by sending a crafted HTTP
    request to the affected software. A successful exploit could allow the
    attacker to delete arbitrary files from the affected system.

    There are no workarounds that address this vulnerability.
