New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 9.6


The remote host is missing a vendor-supplied security patch.


According to its self-reported version, the CUCM IM and Presence Service installed on the remote host contains a version of GNU Bash that is affected by a command injection vulnerability known as Shellshock, which is due to the processing of trailing strings after function definitions in the values of environment variables. This allows a remote attacker to execute arbitrary code via environment variable manipulation depending on the configuration of the system.


Upgrade to Cisco Unified Presence Server 10.5(1.12900.2) or later.
