Published: April 11, 2026
Official Description
In all versions of BIG-IP, when running in Appliance mode, an authenticated user assigned the Administrator role may be able to bypass Appliance mode restrictions, utilizing an undisclosed iControl REST endpoint. A successful exploit can allow the attacker to cross a security boundary.
Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
Risk Analysis
BIG-IP appliances running in Appliance mode have a vulnerability that allows an authenticated Administrator role user to bypass mode restrictions. This bypass can be achieved using an undisclosed iControl REST endpoint, potentially allowing the attacker to cross security boundaries. This CVE is confirmed to be exploited in the wild, indicating a critical and active threat.
This vulnerability is actively being exploited in the wild. An authenticated Administrator role user can bypass Appliance mode restrictions.
Apply the latest security updates for BIG-IP. Ensure that only trusted and necessary users have Administrator role access.
Technical Analysis
CVE-2022-41800 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2022-41800 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
