VAR-200707-0276
Vulnerability from variot - Updated: 2025-04-10 23:01Cross-site scripting (XSS) vulnerability in the Belkin G Plus Router F5D7231-4 with firmware 4.05.03 allows remote attackers to inject arbitrary web script or HTML via a hostname of a DHCP client. The Belkin G Plus Router is prone to an HTML-injection vulnerability because it fails to sufficiently sanitize user-supplied input data. Exploiting this issue may allow an attacker to execute HTML and script code in the context of the device, to steal cookie-based authentication credentials, or to control how the site is rendered to the user; other attacks are also possible. Firmware version 4.05.03 is vulnerable; other versions may also be affected.
Try a new way to discover vulnerabilities that ALREADY EXIST in your IT infrastructure.
The Full Featured Secunia Network Software Inspector (NSI) is now available: http://secunia.com/network_software_inspector/
The Secunia NSI enables you to INSPECT, DISCOVER, and DOCUMENT vulnerabilities in more than 4,000 different Windows applications.
Input passed via the hostname when listing DHCP clients is not properly sanitised before being used. This can be exploited to execute arbitrary HTML and script code in an administrator's browser session in context of an affected interface.
SOLUTION: List DHCP clients in a trusted network environment only.
