CVE-2022-29953Network attack vector

Remote code execution via hardcoded maintenance credentials

Published Jul 26, 2022 · Updated Aug 3, 2024

Hardcoded credentials in Bently Nevada 3701/4X before 4.1 and 60M100 allow remote attackers to execute code or interrupt service. The TCP port 4001 maintenance interface accepts undocumented credentials embedded in the firmware instead of site-specific credentials. Network reachability to the interface is the only reported gate, and successful authentication grants its debug and process-execution capabilities.
