Technical details

A stack-based buffer overflow vulnerability exists in the Tenda HG7, HG9, and HG10 router firmware (version 300001138_en_xpon). The flaw is located within the 'asp_voip_OtherSet' function in the '/boaform/voip_other_set' component of the Web Management Interface. By sending a specially crafted request with a manipulated 'funckey_transfer' argument, a remote attacker with low-level authentication can overflow a buffer on the stack. This can result in a denial of service (system crash) or the execution of arbitrary code with the privileges of the web server.
