CVE-2020-6777Network attack vector

Cross-user script execution via stored management input

Published Jan 14, 2021 · Updated Sep 17, 2024

Stored XSS in PRAESIDEO 4.41 and earlier and PRAESENSA 1.10 and earlier allows remote authenticated users to run scripts in another user’s browser. The web management interface stores administrator-supplied script content without neutralization and returns it when a later user logs in; Bosch has not identified the accepting field or handler. Administrator access is required to plant the script, and execution is limited to the later user’s browser session and management-interface privileges.
