Code execution via unvalidated updater certificate
Published Apr 1, 2024 · Updated Aug 2, 2024
Improper certificate validation in PDF-XChange Editor 10.1.1.381 allows attackers to execute code through its update channel. The updater accepts a server certificate without proper validation, allowing a man-in-the-middle attacker to substitute and launch an installer from the wrong server. No user interaction or prior product authentication is required, but the attacker must occupy an adjacent network position; code runs as the current user.

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 <=10.1.2.382
