According to its self-reported version, Cisco Unified Communications Manager is affected by a vulnerability that allows an unauthenticated, remote attacker to bypass security restrictions. This is due to improper handling of malformed HTTP methods. An attacker can exploit this vulnerability by sending a crafted HTTP request in order to gain unauthorized access to the affected system.
Please see the included Cisco BIDs and Cisco Security Advisory for more information.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
