Privilege escalation via stored saveNodeLabel script injection
Published May 3, 2024 · Updated Sep 18, 2024
Stored XSS in NETGEAR ProSAFE NMS300 before 1.7.0.31 allows remote authenticated users to escalate privileges through a node label. The saveNodeLabel method accepts user-supplied label data without proper validation, stores it, and permits arbitrary script execution. A low-privileged account and victim interaction are required; the script runs in the victim's browser and reaches resources protected from the attacker.
