Privilege escalation via brute-force serial-port cracking
Published Jun 20, 2024 · Updated Aug 2, 2024
Improper permission preservation in ZTE ZXHN H388X V10.1 AGZHM_1.3.1 allows physically proximate attackers to gain elevated privileges. The flaw is reached by brute-force serial-port cracking, but ZTE has not disclosed the specific operation that incorrectly preserves permissions. Physical serial-port access, high-complexity brute forcing, and a common-user context are required to cross the device privilege boundary.
