Detailsinfo

A vulnerability, which was classified as critical, has been found in Cisco Finesse, SocialMiner, Unified Communications Manager, Unified Communications Manager IM and Presence Service, Unified Contact Center Express, Unified Intelligence Center, Unity Connection and Virtualized Voice Browser. This issue affects some unknown processing of the component CLI. The manipulation of the argument command with an unknown input leads to a command injection vulnerability. Using CWE to declare the problem leads to CWE-77. The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

A vulnerability in the CLI of multiple Cisco Unified Communications products could allow an authenticated, local attacker to execute arbitrary commands on the underlying operating system of an affected device as the root user. This vulnerability is due to improper validation of user-supplied command arguments. An attacker could exploit this vulnerability by executing crafted commands on the CLI of an affected device. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system of an affected device as the root user. To exploit this vulnerability, the attacker must have valid administrative credentials.
