Man-in-the-middle interception via unvalidated chain roots
Published Oct 14, 2019 · Updated Aug 5, 2024
Certificate validation bypass in Dogtag PKI JSS allows remote attackers to have crafted certificate chains accepted by applications. CryptoManager's Leaf and Chain OCSP policy treats the chain's root certificate as trusted and performs no validation of that root. Exposure requires an application to select this non-default policy; an accepted attacker-controlled chain enables man-in-the-middle reading or modification of protected traffic without interrupting service.

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=affects >= 4.4.6
- Affected versionversion=affects >= 4.5.3
- Affected versionversion=affects >= 4.6.0
