CVE-2023-30550Public exploitNetwork attack vector

Cross-project modification via unchecked project identifier

Published May 4, 2023 · Updated Jan 29, 2025

IDOR in FIT2CLOUD MeterSphere before 2.9.0 allows remote authenticated users to modify projects they do not administer. The project-update request accepts a user-controlled project identifier without verifying administration rights for the referenced project. Exploitation requires project-administrator access and an intercepted update request; it permits unauthorized changes to another project in the same workspace.
