Opentext · Opentext Documentum Administrator · CVE-2017-14526
**Name of the Vulnerable Software and Affected Versions**
OpenText Documentum Administrator version 7.2.0180.0055
**Description**
The issue is related to incorrect restriction of XML external entities (XXE) in the OpenText Documentum Administrator. This can be exploited by a remote attacker to read arbitrary files, cause a denial of service, or obtain user hashes on Windows systems. The exploitation involves crafted XML structures, such as a DTD, in requests to specific API endpoints like `xda/com/documentum/ucf/server/transport/impl/GAIRConnector`, or through the import or check-in of crafted XML files in a MediaProfile file.
**Recommendations**
For OpenText Documentum Administrator version 7.2.0180.0055, consider disabling the import and check-in functionality for XML files in MediaProfile until a patch is available. Restrict access to the `xda/com/documentum/ucf/server/transport/impl/GAIRConnector` endpoint to minimize the risk of exploitation. Avoid using crafted DTDs or XML structures in requests to prevent potential attacks. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
