Detailsinfo

A vulnerability classified as problematic has been found in Cisco Unified Communications Manager 11.5(1.10000.6) (Unified Communication Software). Affected is some unknown functionality of the component Web Framework. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on confidentiality. CVE summarizes:
