CVE-2022-43376Network attack vector

Browser code and session manipulation via XSS

Published Apr 18, 2023 · Updated Feb 5, 2025

Cross-site scripting in Schneider Electric NetBotz 4.x Appliance 4.7.0 and earlier allows remote attackers to manipulate code and sessions. Schneider Electric states only that malicious code is inserted into the browser and has not disclosed the affected input, page, or rendering operation. Exploitation requires a victim to render the injected content; successful execution can manipulate browser code and session state without prior attacker authentication.
