CVE-2023-41878Network attack vector

Authenticated VNC access via hard-coded default password

Published Sep 26, 2023 · Updated Sep 23, 2024

Hard-coded credentials in FIT2CLOUD MeterSphere 2.10.6 LTS and earlier allow remote authenticated users to access Selenium VNC. The installer publishes ports 5900 and 5901 for Selenium Chrome and Firefox containers whose VNC service accepts the shared default password secret. Exploitation requires a running Selenium container and network reachability to either port, granting access to the desktop session and its available privileges.
