CVE-2023-46282Network attack vector

Browser script execution via reflected web input

Published Dec 12, 2023 · Updated Jan 14, 2025

Reflected XSS in Siemens UMC before 2.11.2 allows remote attackers to run JavaScript in a user's browser through a crafted link. Siemens identifies the UMC web interface as the affected locus but does not disclose the reflected endpoint, parameter, or exact output-handling error. A legitimate user must open an untrusted link; the script then runs in that user's web context with access bounded by the user's interface privileges.
