A vulnerability classified as critical has been found in EMC OpenText Documentum Content Server up to 7.3. Affected is an unknown function of the component TAR File Handler. 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, and integrity. CVE summarizes:
OpenText Documentum Content Server (formerly EMC Documentum Content Server) through 7.3 contains the following design gap, which allows an authenticated user to gain superuser privileges: Content Server allows uploading content using batches (TAR archives). When unpacking TAR archives, Content Server fails to verify the contents of an archive, which causes a path traversal vulnerability via symlinks. Because some files on the Content Server filesystem are security-sensitive, this leads to privilege escalation.
