Script execution via stored administrative content
Published Feb 28, 2024 · Updated Nov 26, 2024
Stored cross-site scripting in ELECOM router firmware allows remote authenticated users to run script in another administrator's browser. An administrative configuration accepts crafted content and later renders it to a different administrator without adequate neutralization; ELECOM has not identified the affected field or rendering routine. Exploitation requires two administrative sessions and enables access to browser-visible management data, with no reported service interruption.
