Client code execution via missing WebSocket origin validation
Published Mar 8, 2024 · Updated Aug 12, 2024
Missing WebSocket origin validation in OpenText Documentum D2 16.5.1 through CE 23.2 allows remote authenticated users to execute client code. The WebSocket handshake accepts requests without validating the Origin header, enabling a cross-origin browser context to upload executable content. Exploitation requires an authenticated D2 session and client user interaction; the reported result is client integrity compromise, not disclosure or service interruption.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=16.5.1 <=ce_23.2
- Affected versionversion=16.5.1 <=CE 23.2
