CVE-2023-44297

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 disclose or alter data, execute code, or interrupt service. Dell identifies the affected locus only as active debug code and does not disclose which firmware component or operation leaves it enabled. Physical access is required; successful exploitation can bypass firmware protections and compromise the server.
