CVE-2022-23127Network attack vector

Credential theft via reflected monitoring-screen script injection

Published Jan 21, 2022 · Updated Aug 3, 2024

Reflected XSS in MC Works64 4.04E and earlier and MobileHMI 10.96.2 and earlier allows remote attackers to steal server authentication information. The mobile-monitoring server fails to validate a monitoring-screen URL before delivering it to the mobile application, allowing the injected script to run in the legitimate user's context. Exploitation requires no prior authentication but requires a legitimate user to open the crafted URL; stolen credentials permit any operation available to that account.
