Technical details

This vulnerability is classified as an insertion of sensitive information into log files (CWE-532). The firmware for CHARX SEC-3xxx charging controllers incorrectly writes the credentials for the 'user-app' account into system logs. A local attacker with low-privileged access to the file system or log services can retrieve these credentials to authenticate via SSH as the 'user-app' user. This level of access can be used to interrupt charging services or as a stepping stone for further privilege escalation. The issue is resolved in firmware version 1.9.1.
