Unauthenticated root code execution via path traversal

Published Oct 6, 2026 · Updated Oct 6, 2026

Path traversal in Dell System Update before 2.3.0.0 allows remote attackers to access host files and execute code as root. Dell does not disclose which update path accepts the attacker-controlled pathname or how its directory restriction fails. Exploitation requires user interaction; the advisory does not identify a directly exposed DSU network service.
