Detailsinfo

A vulnerability was found in Cisco Emergency Responder, Finesse, Prime Collaboration Deployment, SocialMiner, Unified Communications Manager, Unified Communications Manager IM and Presence Service, Unified Contact Center Express, Unified Intelligence Center, Unity Connection and Virtualized Voice Browser and classified as problematic. Affected by this issue is an unknown functionality. The manipulation with an unknown input leads to a privilege chaining vulnerability. Using CWE to declare the problem leads to CWE-268. Two distinct privileges, roles, capabilities, or rights can be combined in a way that allows an entity to perform unsafe actions that would not be allowed without that combination. Impacted is confidentiality, integrity, and availability. CVE summarizes:

A vulnerability in multiple Cisco Unified Communications and Contact Center Solutions products could allow an authenticated, local attacker to elevate privileges to root on an affected device. This vulnerability is due to excessive permissions that have been assigned to system commands. An attacker could exploit this vulnerability by executing crafted commands on the underlying operating system. A successful exploit could allow the attacker to escape the restricted shell and gain root privileges on the underlying operating system of an affected device. To successfully exploit this vulnerability, an attacker would need administrative access to the ESXi hypervisor.
