CVE-2025-33020Network attack vector

Sensitive-data disclosure via unencrypted transmission

Published Jul 23, 2025 · Updated Aug 18, 2025

Missing encryption in IBM Engineering Systems Design Rhapsody 9.0.2, 10.0, and 10.0.1 allows remote attackers to read sensitive data. IBM has not disclosed which transmitting component, protocol, or data fields are sent without encryption. Exploitation requires access to the affected network exchange, and the reported consequence is disclosure of highly sensitive information without integrity or availability impact.
