Credential disclosure via interceptable faye session traffic
Published Jun 14, 2023 · Updated Dec 27, 2024
Information disclosure in Proofpoint Threat Response Auto-Pull before 5.10.0 allows attackers on an adjacent network to obtain service credentials. Proofpoint identifies the faye endpoint and interceptable session traffic but has not disclosed the endpoint operation or cryptographic weakness that exposes the credentials. Exploitation requires a man-in-the-middle position or successful cryptanalysis, and the recovered credentials permit impersonation of PTR/TRAP to integrated services.

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.
