Bug ID 1436153: F5OS upgrades fail when SNMP configuration contains special characters.

Last Modified: Oct 21, 2024

Affected Product(s):
F5OS F5OS(all modules)

Fixed In:
F5OS-A 1.8.0, F5OS-A 1.5.2

Opened: Dec 12, 2023

Severity: 2-Critical

Symptoms

As part of some security fixes, added a special character restriction in SNMP configuration in F5OS-A 1.5.1. This resulted in an upgrade failure to 1.5.1. If an upgrade to 1.5.1 is successful, the SNMP configuration will get deleted implicitly.

Impact

If the user encounters this issue, the system will go to an inaccessible state and require a forced downgrade.

Conditions

Upgrade to 1.5.1 fails when the SNMP configuration contains any special characters. The restricted special characters are: /*!<>^,/

Workaround

Delete the SNMP configuration (community, target, or user) containing special characters before performing an upgrade to 1.5.1.

Fix Information

The special characters in the SNMP configuration do not inject any security issues and can have special characters. Hence, the special characters restriction is removed in F5OS-A 1.5.2 and F5OS-A 1.8.0.
