Opentext Documentum Webtop
The issue is related to an XML external entity (XXE) vulnerability in the web interface of OpenText Documentum Webtop. This vulnerability 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 crafted 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.
