Service interruption via man-in-the-middle channel access
Published May 10, 2023 · Updated Jan 27, 2025
CWE-300 in SEL Real-Time Automation Controller firmware allows remote attackers to interrupt service through a man-in-the-middle attack. SEL has not disclosed which RTAC communication channel lacks endpoint verification or the exact message handling that triggers the interruption. Exploitation requires an on-path network position and user interaction; the published consequence is an unspecified denial-of-service condition.
