Summary

  o A vulnerability in Cisco Unified Contact Center Express (UCCX) Software
    could allow an unauthenticated, remote attacker to conduct an HTTP response
    splitting attack.

    The vulnerability is due to insufficient input validation of some
    parameters that are passed to the web server of the affected system. An
    attacker could exploit this vulnerability by convincing a user to follow a
    malicious link or by intercepting a user request on an affected device. A
    successful exploit could allow the attacker to perform cross-site scripting
    attacks, web cache poisoning, access sensitive browser-based information,
    and similar exploits.

    Cisco has released software updates that address this vulnerability. There
    are no workarounds that address this vulnerability.
