CWE-1299 (Missing Protection Mechanism for Alternate Hardware Interface) documents a weakness type used across vulnerability databases and security assessments. Use the sections below for definition, context, and mapped CVEs.
The lack of protections on alternate paths to access control-protected assets (such as unprotected shadow registers and other external facing unguarded interfaces) allows an attacker to bypass existing protections to the asset that are only performed against the primary path.
