CVE-2024-5634

Telnet access via predictable firmware-shared passwords

Published Jul 9, 2024 · Updated Aug 1, 2024

Weak credentials in LBH30FE200W-based camera firmware allow attackers to gain Telnet access by brute-forcing a patterned password. The Telnet password follows a predictable scheme, and cameras running the same firmware version reuse the same password, sharply reducing the search space. Reachability of the camera's Telnet service is required; a successful guess grants the privileges assigned to that account.
