Detailsinfo

A vulnerability classified as problematic was found in Cisco Unified Computing System (Virtualization Software) (the affected version is unknown). This vulnerability affects an unknown code of the component RBAC. The manipulation with an unknown input leads to a input validation vulnerability. The CWE definition for the vulnerability is CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

A vulnerability in the role-based access-checking mechanisms of Cisco Unified Computing System (UCS) Software could allow an authenticated, local attacker to execute arbitrary commands on an affected system. The vulnerability exists because the affected software lacks proper input and validation checks for certain file systems. An attacker could exploit this vulnerability by issuing crafted commands in the CLI of an affected system. A successful exploit could allow the attacker to cause other users to execute unwanted arbitrary commands on the affected system. Cisco Bug IDs: CSCvf52994.
