A stack-based buffer overflow in the boa web server's formUpload() functionality of the Totolink X2000R router firmware allows an attacker to overflow a stack buffer. The attacker needs to be able to send HTTP requests to the device and to be authenticated, and a specially crafted request can then lead to arbitrary code execution.
