Severity: 3-Major


Config Sync will fail with the following error message: Configuration error: system filter (/Common/allow-all) is part of system configuration, so it cannot be modified


Config sync fails.


It is not known all of the conditions that trigger this, but it was discovered in a configuration containing an apm rule in urldb_base.conf: apm url-filter allow-all { }


None - resetting device trust and re-establishing the device group may cause the problem to correct itself.

Fix Information

Fix the validation for url filter correctly, so that validation logic is skipped during config sync.
