CVE-2022-36783Network attack vector

Script execution via unneutralized IntersectudRule reflection

Published Oct 25, 2022 · Updated May 7, 2025

Reflected XSS in AlgoSec FireFlow A32.0, A32.10, and A32.20 allows remote authenticated users to run script in a victim's browser. The search/result.html handler reflects the IntersectudRule query value into its response without neutralizing JavaScript. An authenticated attacker must convert the request from POST to GET and persuade another user to open the crafted URL; successful execution occurs in that user's browser context.
