CVE-2023-28512Network attack vector

Unauthenticated data manipulation

Published Mar 3, 2024 · Updated Aug 2, 2024

Improper input validation in IBM Watson CP4D Data Stores 4.6.0, 4.6.1, and 4.6.2 allows remote attackers to manipulate data. IBM has not disclosed the affected request handler, parameter, or validation operation that permits the data change. Exploitation requires no authentication or user interaction, but it requires specific system knowledge and high-complexity conditions; the documented consequence is limited to integrity loss.
