Authenticated agent traffic hijack via condition mishandling
Published Sep 13, 2023 · Updated Sep 24, 2024
Improper exceptional-condition handling in Proofpoint Insider Threat Management Server before 7.14.3.69 allows agent traffic hijacking. During an exceptional condition, the server accepts an attacker-chosen communications URL when changing an already-registered agent's configuration; Proofpoint has not named the responsible endpoint or failed check. Remote authenticated users need valid agent credentials and its hostname; future monitored PII and intellectual-property events can then be read, altered, or deleted in transit.

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=0 <=7.14.3
- Affected versionversion=0 <=7.14.3 changes=[{"at":"7.14.3.69","status":"unaffected"}]
