Browser script execution via malicious configuration upload

Published Sep 18, 2023 · Updated Aug 2, 2024

Cross-site scripting in Socomec MODULYS GP web firmware 01.12.10 allows remote attackers to execute browser code via a configuration upload. The web application accepts a device configuration file containing malicious script content and incorporates it into generated web output without neutralization. No account or user interaction is required; the injected code can read or alter browser-accessible information but is not reported to interrupt the UPS service.
