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.
-
Verify Windows operating systemCheck if the system is running Windows by running 'systeminfo' in command prompt or checking OS name in System Properties. This vulnerability only affects Windows installations.Affected if System is NOT running Windows - the vulnerability does not apply to non-Windows systems
-
Check Juniper Installer Service Client versionNavigate to Windows Control Panel > Programs and Features, or run 'wmic product get name,version' to list installed software. Look for 'Juniper Installer Service Client' and note the version number.Affected if Version is 7.1, 7.2, 7.3, or 7.4 (any of these versions are affected)
-
Check Junos Pulse Client versionNavigate to Windows Control Panel > Programs and Features, or run 'wmic product get name,version' to list installed software. Look for 'Junos Pulse Client' and note the version number.Affected if Version is 4.0 or any version <= 4.0 (these versions are affected)
-
Confirm both applications are presentSearch the installed programs list for both 'Juniper Installer Service Client' and 'Junos Pulse Client'. Both are required for this specific vulnerability to be relevant.Affected if Neither application is installed - the vulnerability does not apply
The system is affected if it is running Windows AND has Juniper Installer Service Client version 7.1-7.4 OR Junos Pulse Client version 4.0 or lower installed.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade Juniper Installer Service Client to version 7.4R6 or later, and Junos Pulse Client to version 4.0R6 or later. Alternatively, if upgrades are not feasible, restrict local user access to systems running these applications.
