CVE-2024-8411Public exploitNetwork attack vector

Reflected XSS via unencoded Sub_Expresion parameter

Published Sep 4, 2024 · Updated Feb 26, 2026

Cross-site scripting in ABCD 2.2.0-beta-1 allows remote authenticated users to execute script via the Sub_Expresion parameter. buscar_integrada.php returns the Sub_Expresion query value in HTML without context-appropriate output encoding, so injected event-handler markup executes in the page. Exploitation requires a victim to open a crafted search URL, and the script runs with the victim's access to the ABCD web origin.
