Summary
Xovis AG APS-R-POE, APS-R-POE-PP, APS-R, APS-R-POE-USB, and APS-B 2.10.1.1 and earlier contain an OS command injection flaw in /sbin/ImportParamSet.sh. The script embeds the symlink target path from uploaded parameter archive files into a shell command without quoting or sanitization (CWE-78). A remote attacker with low privileges can run commands as root by uploading a crafted parameter archive, gaining full control of the device.
