CVE-2023-6761Network attack vector

Authenticated modification of user data

Published Dec 13, 2023 · Updated Aug 2, 2024

Improper access control in the User Data Handler in Thecosy IceCMS 2.0.0 and 2.0.1 allows remote authenticated users to modify user data. The CNA identifies only unknown processing in that component and does not disclose the request, code path, or incorrect authorization operation. Low-privileged access is required, and the CNA bounds the impact to unauthorized modification without reported disclosure or service interruption.
