CVE-2023-44298

Code execution via active debug code

Published Dec 5, 2023 · Updated Aug 2, 2024

Active debug code in Dell PowerEdge BIOS 1.4.4 allows physically proximate attackers to alter information and interrupt service. Dell identifies active debug code but has not published the affected routine, debug interface, or operation that remains exposed. Exploitation requires unauthenticated physical access and high complexity; successful use can modify data, execute code, or interrupt service, with no confidentiality impact reported.
