Technical details
A use of default password vulnerability (CWE-1393) exists in syslink software AG Avantra on both Linux and Windows platforms. The software utilizes common or default usernames and passwords that are not automatically changed during installation. An attacker who has already obtained high-privileged local access (PR:H) to the host operating system can leverage these known credentials to authenticate to the Avantra application. This allows for unauthorized data retrieval and minor integrity impacts. The issue is resolved in Avantra version 25.3.0.
