Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed BIG-IP Edge Client versionOn the Windows system, check the installed version of BIG-IP Edge Client. This can typically be found in Add/Remove Programs, or by checking the application's version information if already installed.Affected if The installed version falls between 7.2.2 and 7.2.3.0 inclusive.
-
Check Access Policy Manager versionVerify the version of F5 Big Ip Access Policy Manager (APM) installed in the environment. Compare against the affected version ranges: 7.2.2 to <7.2.3.1, 13.1.0 to 13.1.5, 14.1.0 to 14.1.5, 15.1.0 to 15.1.8, 16.1.0 to 16.1.3, or 17.0.0 to <17.0.0.2.Affected if The APM version matches any of the listed affected ranges.
-
Confirm Windows installer is in useDetermine whether the Windows version of the BIG-IP Edge Client installer is being used, since this DLL hijacking vulnerability affects only the Windows installer package.Affected if The Windows installer for BIG-IP Edge Client version 7.2.2 to 7.2.3.0 is present or was recently used.
-
Check for F5 Big Ip Edge installationIdentify if F5 Big Ip Edge client is installed, as the vulnerability listing indicates all versions of this product are affected.Affected if F5 Big Ip Edge client of any version is installed on the system.
You are affected if BIG-IP Edge Client Windows Installer version 7.2.2 through 7.2.3.0 was used, or if any version of F5 Big Ip Edge client is installed, or if Access Policy Manager matches the vulnerable version ranges.
