CVE-2023-38582Network attack vector

Victim-browser script execution via MAIL_RCV injection

Published Sep 18, 2023 · Updated Jun 18, 2025

Stored XSS in Socomec MODULYS GP web firmware 01.12.10 allows remote authenticated users to execute JavaScript in a victim's browser. The web application stores an XSS payload submitted through MAIL_RCV and later inserts it into the vulnerable page without neutralizing executable content. An attacker needs authenticated access to set the field, and a legitimate user must open the affected page, exposing that user's browser session.
