The Bently Nevada 3700 series of condition monitoring equipment through 2022-04-29 has a maintenance interface on port 4001/TCP with undocumented, hardcoded credentials. An attacker capable of connecting to this interface can thus trivially take over its functionality.

The Bently Nevada 3700 series of condition monitoring equipment through 2022-04-29 has a maintenance interface on port 4001/TCP with undocumented, hardcoded credentials. An attacker capable of connecting to this interface can thus trivially take over its functionality.

The affected product has credentials for the maintenance interface hardcoded in the firmware. The maintenance interface allows for debug and process execution capabilities, which could allow remote code execution or cause a denial-of-service condition.CVE-2022-29953 has been assigned to this vulnerability. A CVSS v3 base score of 9.1 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H). The affected product uses protocols to provide configuration management and historical data related functionality without any authentication features, which may allow an attacker to read or write files on the controllers or cause a denial-of-service condition.CVE-2022-29952 has been assigned to this vulnerability. A CVSS v3 base score of 7.4 has been calculated; the CVSS vector string is (AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:H).
