Unauthorized controller access via improperly restricted debug interface
Published Sep 28, 2026 · Updated Sep 28, 2026
Improper debug access control in Dell BOSS before 2.2.13.2038 lets physically proximate attackers gain unauthorized access. The SMCU's on-chip debug and test interface lacks adequate access restrictions, but Dell has not disclosed the exact bypass or operations exposed. Exploitation requires physical access to a 17G BOSS-N1 controller; Dell describes the result only as unauthorized access, leaving specific data or control capabilities undisclosed.
