Information disclosure via unauthenticated DNS lookups
Published Jun 27, 2023 · Updated Nov 6, 2024
Authorization bypass in Proofpoint Insider Threat Management Server before 7.14.3 allows remote attackers to disclose content via DNS lookups. Multiple URL-validation endpoints process anonymous requests and resolve attacker-controlled content through DNS without checking authorization. Exploitation requires adjacency to the server network; the documented consequence is limited to confidentiality loss through DNS.

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.
