CWE-427

Summary

  * A vulnerability in the Cisco FindIT Network Discovery Utility could allow
    an authenticated, local attacker to perform a DLL preloading attack,
    potentially causing a partial impact to the device availability,
    confidentiality, and integrity.

    The vulnerability is due to the application loading a malicious copy of a
    specific, nondefined DLL file instead of the DLL file it was expecting. An
    attacker could exploit this vulnerability by placing an affected DLL within
    the search path of the host system. An exploit could allow the attacker to
    load a malicious DLL file into the system, thus partially compromising
    confidentiality, integrity, and availability on the device.

    There are no workarounds that address this vulnerability.
