Description

ZF Roll Stability Support Plus (RSSPlus)
is vulnerable to an authentication bypass vulnerability targeting
deterministic RSSPlus SecurityAccess service seeds, which may allow an
attacker to remotely (proximal/adjacent with RF equipment or via pivot
from J2497 telematics devices) call diagnostic functions intended for
workshop or repair scenarios. This can impact system availability,
potentially degrading performance or erasing software, however the
vehicle remains in a safe vehicle state.
