CVE-2017-11320

25
FAUCET Score

CVE-2017-11320 describes a persistent Cross-Site Scripting (XSS) vulnerability in Technicolor TC7337 routers (firmware version 08.89.17.20.00) that allows an attacker to inject malicious scripts via the SSID of nearby Wi-Fi devices. This medium-severity vulnerability (CVSS 6.1) can lead to DNS poisoning and credential theft from the router, requiring user interaction (UI:R) for successful exploitation. While not actively exploited in the wild and lacking Metasploit or Nuclei modules, a public exploit (EDB-42427) exists, though community discussion and media coverage are minimal.
