What is CVE-2017-15276?
CVE-2017-15276 is a high-severity path traversal vulnerability in n/a, published on 13 Oct 2017. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
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.
Weakness: CWE-22
