CVE-2025-33077Network attack vector

Authenticated code execution via stack buffer overflow

Published Jul 23, 2025 · Updated Feb 26, 2026

Stack-based buffer overflow in IBM Engineering Systems Design Rhapsody 9.0.2, 10.0, and 10.0.1 allows remote authenticated users to execute code. IBM has not disclosed the affected component or input, only that improper bounds checking permits a stack buffer to overflow. IBM describes the attacker as a local user, while its CVSS vector rates the path as network-reachable and requiring low privileges.
