BIG-IP versions 14.1.0 14.1.5
BIG-IP versions 13.1.0 13.1.5
Successful exploitation of the vulnerability could lead to remote code execution of an affected system with the Configuration utility exposed.
Security updates for affected systems are now available. System administrators of affected systems should follow the recommendations provided by the product vendor and take immediate actions to mitigate the risk.
In case the security updates could not be applied immediately, system administrators should restrict access to the Configuration utility of vulnerable systems to only trusted users and devices over a secure network as recommended by the product vendor.
