Users with Deny Config Write privilege can trigger some VLAN interface operations
Added by Steve Wheeler 3 months ago.
Updated about 2 months ago.
Plus Target Version:
24.03
Description
A user with the Deny Connfig Write privilege set but access to the interfaces config pages can try to create VLANs and QinQ interfaces.
The interfaces fail to be created correctly and are not added to the config but the underlying ifconfig commands are still run creating the interfaces on the system.
Those bogus interfaces then appear as assignable and although that user cannot assign them another user could, creating invalid config.
Other interface types do not seem affected; GRE PPP etc
Tested this on 24.03 builds from Feb 23rd. Can confirm this issue is present.

Looks good on the current snapshot. Trying to create, save, or delete a VLAN as a user with that privilege displays an appropriate error and no action is taken.
Rephrased the subject since it wasn't quite right. The changes weren't saved but some operations still happened in the OS level.
- Status changed from Resolved to In Progress
A user with deny config write can no longer create VLANs in current snapshots but can still create QinQ interfaces:
