Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The Mobile Code filter in ZoneAlarm Pro 5.0.590.015 does not filter mobile code within an SSL encrypted session, which could allow remote attackers to bypass the mobile code filtering. NOTE: it has been disputed by the vendor that this behavior is required by the SSL specification.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

The ZoneAlarm Pro 5.0.590.015 mobile code filter fails to inspect SSL-encrypted sessions for mobile code (Java applets, ActiveX, etc.), allowing malicious mobile code to bypass filtering when transported through encrypted channels.

MitigationUpgrade to a current version of ZoneAlarm or implement alternative security controls that can inspect SSL traffic for mobile code threats while maintaining the SSL inspection capability.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Verify ZoneAlarm Pro installation
    Check if ZoneAlarm Pro is installed on the system by reviewing installed programs in Control Panel > Programs and Features, or checking for ZoneAlarm Pro in the system tray
    Affected if ZoneAlarm Pro is not installed, the system is not affected by this specific CVE
  2. Confirm exact version number
    Open ZoneAlarm Pro interface and navigate to About/Version information, or check the Windows registry under HKEY_LOCAL_MACHINE\SOFTWARE\Zone Labs\ZoneAlarm Pro for the Version value
    Affected if Version is exactly 5.0.590.015, the system is affected
  3. Verify mobile code filter is enabled
    In ZoneAlarm Pro, navigate to Program Control > Mobile Code (or similar mobile code filtering settings) and confirm the filter is turned on
    Affected if Mobile code filtering is disabled, the vulnerability cannot be exploited even on the affected version
  4. Check if SSL inspection is configured
    In ZoneAlarm Pro settings, look for SSL inspection, HTTPS inspection, or encrypted session filtering options under the mobile code or firewall settings
    Affected if SSL-encrypted sessions are not being inspected while mobile code filtering is enabled, the bypass vulnerability is present

The system is affected only if ZoneAlarm Pro version 5.0.590.015 is installed with mobile code filtering enabled and SSL-encrypted sessions are not being inspected for mobile code.
