They should also review system logs for any suspicious SSH access attempts and consider implementing additional security controls such as two-factor authentication for SSH access.

Technical summary

The vulnerability is caused by an improper signature verification in the SSH enablement mechanism of multiple Lenze products. This allows a low-privileged local attacker to bypass verification of the SSH enable file signature and enable SSH access on the device. The vulnerability has a CVSS score of 8.5 and is classified as HIGH severity. Affected product deployments should be identified in managed environments and owners assigned for follow-up. The CVE record and NVD detail page provide further information on the vulnerability. System administrators should review system logs for any suspicious SSH access attempts and consider implementing additional security controls such as two-factor authentication for SSH access.
