eEye SecureIIS versions 1.0.3 and earlier allows a remote attacker to bypass filtering of requests made to SecureIIS by escaping HTML characters within the request, which could allow a remote attacker to use restricted variables and perform directory traversal attacks on vulnerable programs that would otherwise be protected.

Security readout for executives and security teams

This is a legacy web-filter bypass in eEye SecureIIS 1.0.3 and earlier. A remote attacker could evade SecureIIS filtering by encoding HTML characters in requests, potentially reaching restricted variables or triggering directory traversal in applications the product was meant to protect. Exposure is most likely in old IIS environments that still depend on eEye SecureIIS 1.0.3 or earlier. Modern exposure is probably rare, but legacy internet-facing servers or archived business applications should be checked. Prioritize this if any legacy IIS server still uses SecureIIS. The business risk is not the age of the CVE; it is continued reliance on an obsolete security filter that can be bypassed remotely. Mitigation focus: Inventory IIS servers for eEye SecureIIS and confirm installed versions.; Do not rely on SecureIIS 1.0.3 or earlier as the only control.; Check vendor or historical guidance for fixed versions or replacement advice..
