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
AlgoSec – FireFlow Reflected Cross-Site-Scripting (RXSS) A malicious user injects JavaScript code into a parameter called IntersectudRule on the search/result.html page. The malicious user changes the request from POST to GET and sends the URL to another user (victim). JavaScript code is executed on the browser of the other user.

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 confidence

AlgoSec FireFlow contains a reflected cross-site scripting (XSS) vulnerability in the search/result.html page. The 'IntersectudRule' parameter is vulnerable to XSS when the request method is changed from POST to GET, allowing attackers to craft malicious URLs that execute arbitrary JavaScript in victims' browsers.

MitigationImplement proper input validation and output encoding for the IntersectudRule parameter on the search/result.html page. Additionally, configure the application to reject GET requests for operations intended to be POST-only.

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. Identify installed FireFlow version
    Check the product UI for version information (typically in About/Help section) or look for version files in the installation directory. Compare against affected ranges: a32.0 to a32.0.580-277, a32.10 to a32.10.410-212, or a32.20 to a32.20.230-35
    Affected if Installed version falls within any of the affected version ranges
  2. Verify search/result.html endpoint exists
    Confirm the /search/result.html endpoint is accessible on the FireFlow web interface by attempting to access it or reviewing web server configuration
    Affected if The endpoint exists and is reachable via the web application
  3. Test GET request acceptance on vulnerable endpoint
    Send a GET request to search/result.html with a test value in the IntersectudRule parameter (e.g., ?IntersectudRule=test) and observe if the application accepts and reflects the parameter
    Affected if The application accepts GET requests and reflects the IntersectudRule parameter in the response without proper encoding
  4. Inspect parameter handling in HTTP traffic
    Capture and review HTTP traffic when using the search functionality to confirm whether the IntersectudRule parameter is processed and echoed back in responses
    Affected if The parameter is reflected in the response unencoded or unsanitized
  5. Check application configuration for request method restrictions
    Review application or web server configuration files to determine if endpoints are configured to reject GET requests for operations designed for POST only
    Affected if The application allows GET requests where POST should be required, enabling the XSS vector

A user is affected if their installed FireFlow version falls within the listed ranges AND the search/result.html endpoint accepts GET requests with the IntersectudRule parameter being reflected without proper encoding.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Implement proper input validation and output encoding for the IntersectudRule parameter on the search/result.html page. Additionally, configure the application to reject GET requests for operations intended to be POST-only.

Recommended fix High confidence

a32.0.580-277 (or later in same branch); a32.10.410-212 (or later); a32.20.230-35

  1. Identify the currently installed FireFlow version by checking the AlgoSec console or system information
  2. For the a32.0 branch: upgrade to version a32.0.580-277 or later
  3. For the a32.10 branch: upgrade to version a32.10.410-212 or later
  4. For the a32.20 branch: upgrade to version a32.20.230-35 or later
  5. After upgrade, verify the fix by testing that the IntersectudRule parameter on search/result.html properly encodes special characters and does not execute injected JavaScript
