Unauthenticated disclosure of server-accessible critical data
Published Oct 20, 2021 · Updated Sep 25, 2024
Information disclosure in the OSSL Module of Oracle HTTP Server 11.1.1.9.0 allows remote attackers to read critical data via HTTPS. Oracle has not published the vulnerable OSSL Module operation or the HTTPS input that triggers the unauthorized read. Exploitation requires unauthenticated network access and high attack complexity; successful attacks expose server-accessible data without modifying it or 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.
