Emerson OpenBSI through 2022-04-29 mishandles credential storage. It is an engineering environment for the ControlWave and Bristol Babcock line of RTUs. This environment provides access control functionality through user authentication and privilege management. The credentials for various users are stored insecurely in the SecUsers.ini file by using a simple string transformation rather than a cryptographic mechanism.

Emerson OpenBSI through 2022-04-29 mishandles credential storage. It is an engineering environment for the ControlWave and Bristol Babcock line of RTUs. This environment provides access control functionality through user authentication and privilege management. The credentials for various users are stored insecurely in the SecUsers.ini file by using a simple string transformation rather than a cryptographic mechanism.

The affected product was found to store credentials in an insecure local file. This could allow an attacker with local access to the system to compromise these stored credentials.CVE-2022-29959 has been assigned to this vulnerability. A CVSS v3 base score of 9.6 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H). The affected product was found to have hardcoded cryptographic keys, which could allow an attacker with local access to the filesystem to elevate their privileges.CVE-2022-29960 has been assigned to this vulnerability. A CVSS v3 base score of 8.1 has been calculated; the CVSS vector string is (AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H).
