Browser script execution via crafted configuration
Published Oct 3, 2023 · Updated Sep 20, 2024
Cross-site scripting in FURUNO SYSTEMS ACERA access point firmware allows remote authenticated users to run script in another user's browser. FURUNO SYSTEMS has not identified the configuration field or output-encoding failure that causes the crafted setting to execute. Exploitation requires ST mode, an authenticated user who creates the crafted configuration, and another logged-in user who views it; the script runs in that user's browser.
