Description

According to its self-reported version, the remote Cisco Unified Communications Manager (CUCM) device is affected by one of the following denial of service vulnerabilities :

  • A flaw exists in the in the 8.6 branch due to improper processing of malformed packets to unused UDP ports. A remote, unauthenticated attacker can cause an interruption of voice services and an inability to access the system's Graphical User Interface (GUI). (CVE-2013-1133 / CSCtx43337)

  • A flaw exists in the 9.0 branch due to the lack of authentication for Intracluster Location Bandwidth Manager (LBM) communication. A remote, unauthenticated attacker can poison LBM transaction records resulting in the interruption of voice services. (CVE-2013-1134 / CSCub28920)
