CVE-2026-40462 Details
Description
Incorrect permission assignment vulnerabilities exist in iControl REST and TMOS shell (tmsh) undisclosed command which may allow an authenticated attacker to view sensitive information. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
A vulnerability exists in iControl REST and the TMOS shell (tmsh) due to incorrect permission assignments in an undisclosed command. This vulnerability may enable an authenticated attacker to access sensitive information. The issue is limited to the control plane and does not involve data plane exposure.
Users can block access to the iControl REST interface through self IP addresses by changing the Port Lockdown setting to 'Allow None' for each self IP address. If necessary, custom options can be used to disallow access to iControl REST while opening other ports. For management interfaces, access should be restricted to trusted users and devices over secure networks. Similar measures can be applied to SSH access through self IP addresses or the management interface.
