CVE-2023-43045Network attack vector

Unauthorized actions via reflected OTP bypass

Published Oct 23, 2023 · Updated Sep 11, 2024

Authentication bypass in IBM Sterling Partner Engagement Manager 6.1.2, 6.2.0, and 6.2.2 allows remote attackers to perform unauthorized actions. IBM identifies the issue as a reflected one-time-password bypass caused by improper authentication, but has not disclosed the affected endpoint or how untrusted input defeats the OTP check. No credentials or user interaction are required, but high attack complexity limits reachability; successful exploitation changes application data or state without reported disclosure or service interruption.
