Administrator credential theft via stored disclaimer script
Published Aug 25, 2023 · Updated Oct 2, 2024
Stored XSS in Stormshield Network Security 3.8.0 allows remote authenticated users to steal administrator credentials. The administrative disclaimer uploader accepts malicious HTML and JavaScript, then renders that content on the administration login interface without neutralization. An administrator with disclaimer-editing rights must store the payload; a later administrator visit can expose browser-saved SSL VPN credentials or replace the login form.
