What is CVE-2018-5547?

The F5 BIG-IP APM client prior to version 7.1.7.1 for Windows employs the Legacy logon mode by default, which utilizes a SYSTEM account for network access. This implementation poses a security risk as it exposes a certificate user interface dialog box featuring a link to the certificate policy. Unprivileged users, upon clicking this link, gain the ability to open additional dialog boxes, potentially accessing the local machine's Windows Explorer and acquiring administrative privileges. This vulnerability arises specifically when the APM client is installed by an administrator on user machines, allowing local users to exploit the situation.
