Security readout for executives and security teams

This is an old web-gateway detection bypass. Under specific legacy conditions involving Secure Computing Secure Web Gateway/Webwasher and Internet Explorer 6 or 7, malicious HTML could evade gateway malware detection. The sources do not provide a CVSS score, affected versions, patch details, or evidence of active exploitation. Likely exposure is limited to organizations still running Secure Computing Secure Web Gateway/Webwasher in a traffic path, especially where IE 6 or 7 remains usable. Most modern environments are unlikely to be exposed unless legacy infrastructure or archival systems remain operational. Prioritize as a legacy exposure check. It becomes business-relevant if Webwasher or IE 6/7 still exists in production, regulated, or remote-access environments. Otherwise, document non-exposure and focus remediation on removing unsupported systems. Mitigation focus: Inventory any Secure Computing Secure Web Gateway or Webwasher deployments.; Check vendor or successor guidance for updates, signatures, or retirement advice.; Remove Internet Explorer 6 and 7 from supported workflows..
