CVE-2024-34274

Code execution via unsafe cookie deserialization

Published May 21, 2024 · Updated Feb 13, 2025

Untrusted deserialization in OpenBD 20210306203917-6cbe797 allows physically proximate attackers to execute code via crafted cookies. OpenBD treats the bdglobals and bdclient_spot cookie values as serialized objects and reconstructs them without validating their contents. Exploitation requires low privileges, physical access, and user interaction, and the affected release is no longer maintained.
