Fixed In:
F5OS-A 1.8.0, F5OS-A 1.5.2
Opened: Dec 12, 2023 Severity: 2-Critical
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.
If the user encounters this issue, the system will go to an inaccessible state and require a forced downgrade.
Upgrade to 1.5.1 fails when the SNMP configuration contains any special characters. The restricted special characters are: /*!<>^,/
Delete the SNMP configuration (community, target, or user) containing special characters before performing an upgrade to 1.5.1.
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.
