Nico Leidecker has reported a vulnerability in the Belkin Wireless G Plus Router, which can be exploited by malicious people to conduct script insertion attacks.
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.
The vulnerability is reported in Belkin Wireless G Plus Router (F5D7231-4) with firmware version 4.05.03. Other versions may also be affected.
Solution: List DHCP clients in a trusted network environment only.
