F5 BIG-IP Web Management Console CSRF Product: F5 BIG-IP http://www.f5.com/products/big-ip/ By design the F5 BIG-IP web management interface allows a logged-in user with Resource Manager or Administrator privileges to execute an arbitrary bigpipe shell command through the web "Console" feature. It is possible to craft URL links that would execute the command with a simple HTTP GET request. Cross-site attacks may leverage this functionality to reconfigure the BIG-IP appliance, including creating new administrators. The vulnerability has been identified in version 9.4.3. However, other versions may be also affected. Solution: Administrators should not browse untrusted sites while logged into the BIG-IP web management interface. It is not possible to log out of the interface so it is important to shut down the browser after the interface is no longer needed. Closing the interface browser window or removing the BIG-IP cookie is not sufficient. Found by: nnposter
