CVE-2007-2689
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 · uneditedCheck Point Web Intelligence does not properly handle certain full-width and half-width Unicode character encodings, which might allow remote attackers to evade detection of HTTP traffic.
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 · high confidenceCheck Point Web Intelligence fails to properly handle full-width and half-width Unicode character encodings in HTTP traffic, allowing attackers to obfuscate malicious requests by using alternative Unicode representations that bypass the security gateway's detection mechanisms.

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 Check Point Web Intelligence installation and versionLocate the Check Point Web Intelligence installation directory and check the version information, typically found in product metadata, about dialog, or version file within the Web Intelligence program folderAffected if The installed version matches the 'gold' release or falls within the affected version range without vendor patches applied
-
Confirm HTTP traffic inspection is enabledAccess the Web Intelligence security policy or gateway configuration and verify that HTTP traffic analysis/scanning features are turned onAffected if HTTP traffic inspection is active, as the vulnerability only affects traffic passing through the security gateway's analysis engine
-
Verify Unicode normalization handling in the gatewayCheck the Web Intelligence configuration settings for HTTP normalization or character encoding handling options, looking for how full-width and half-width Unicode characters are processedAffected if Unicode normalization is either disabled or improperly configured, allowing alternative Unicode representations to pass through unaltered
-
Test for Unicode bypass in active traffic inspectionSend a test HTTP request containing full-width Unicode characters (such as full-width slash %EF%BC%8F or other obfuscated variants) through the gateway and observe whether the request is normalized or passed unchanged to the backendAffected if The gateway fails to normalize Unicode characters and passes alternative encodings through without converting them to standard representations, allowing obfuscated requests to bypass detection
The environment is affected if Check Point Web Intelligence (gold version or unpatched) is installed with HTTP inspection enabled and Unicode normalization is either disabled or ineffective at normalizing full-width/half-width character variants in HTTP requests.

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 dataApply Check Point vendor patches for this vulnerability and verify that HTTP traffic normalization correctly processes Unicode characters; consider supplementary input validation at downstream security layers.
