CVE-2020-7249Public exploitNetwork attack vector

Browser script execution via stored SSID input

Published Jan 21, 2020 · Updated Aug 4, 2024

Stored XSS in SMC D3G0804W 3.5.2.5-LAT_GA allows remote authenticated users to execute script through a crafted SSID. The WiFi Network Configuration page stores the SSID field and later renders it without neutralizing browser-executable content. Administrator access is required to save the payload, and a user must view the affected page before the script runs in that page's origin.
