OS command injection vulnerability exists in BUFFALO wireless LAN routers and wireless LAN repeaters. If a user logs in to the management page and sends a specially crafted request to the affected product from the product's specific management page, an arbitrary OS command may be executed.

The Buffalo WHR-1166DHP 1.60 and earlier, WSR-600DHP 1.60 and earlier, WHR-600D 1.60 and earlier, WHR-300HP2 1.60 and earlier, WMR-300 1.60 and earlier, WEX-300 1.60 and earlier, and BHR-4GRV2 1.04 and earlier routers allow remote authenticated users to execute arbitrary OS commands via unspecified vectors.
