Stored XSS in Skyworth Router CM5100 due to insufficient Hostname validation allows remote attackers to execute arbitrary scripts.

Vulnerability

The vulnerability exists in Skyworth Router CM5100, version 4.1.1.24, and is a stored cross-site scripting issue. The web interface fails to properly validate user-supplied input for the Hostname parameter, allowing injection of malicious scripts [1].

Exploitation

A remote attacker can exploit this by sending specially crafted input to the Hostname parameter via the web interface. No authentication is mentioned as required, so it may be accessible to unauthenticated users. The attacker does not need prior access to the device.

Impact

Successful exploitation leads to stored XSS, meaning the injected script is stored on the server and executed when other users (such as administrators) view the affected page. This could result in session hijacking, defacement, or theft of sensitive information.

Mitigation

No official fix has been released as of January 2024. Users are advised to restrict access to the web interface and monitor for updates from Skyworth. According to CERT-In [1], the severity is rated as HIGH.
