CVE-2024-56524
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 · uneditedRadware Cloud Web Application Firewall (WAF) before 2025-05-07 allows remote attackers to bypass firewall filters by adding a special character to the request.
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 confidenceRadware Cloud WAF before the 2025-05-07 patch fails to properly sanitize or normalize requests containing certain special characters, allowing attackers to craft malicious requests that bypass firewall filter rules. This enables various web application attacks (injection, XSS, etc.) to reach backend systems without WAF blocking.

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 your Radware Cloud WAF versionLog into the Radware Cloud WAF management console and navigate to the version or system information section. Alternatively, check the last update date of your WAF policy or contact Radware support to confirm the current deployed version.Affected if The WAF version or last update date is before 2025-05-07.
-
Confirm WAF security rules are activeAccess the WAF policy configuration in the management console and verify that security rules (including any custom or profile-based rules) are enabled and set to block or detect traffic.Affected if WAF rules are enabled and the version is below 2025-05-07.
-
Review recent security events for bypass patternsExamine WAF access logs and security event logs for any blocked or allowed requests that contain special characters (such as null bytes, Unicode characters, or encoding sequences) that may have successfully reached backend servers.Affected if Malicious requests with special characters were logged as allowed or passed without blocking while WAF rules should have caught them.
-
Audit upstream traffic logsCompare WAF logs with backend application logs to identify any suspicious requests that reached the application but were not blocked or flagged by the WAF.Affected if Requests reached the backend that should have matched WAF security rules, indicating potential bypass.
You are affected if your Radware Cloud WAF is at a version or update date prior to 2025-05-07 and has security rules enabled.

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 data2025-05-07
Update Radware Cloud WAF to a version released on or after 2025-05-07. If immediate patching is not possible, implement additional input validation at the application layer as a compensating control.
