Multiple buffer overflows in WebGate Embedded Standard Protocol (WESP) SDK allow remote attackers to execute arbitrary code via unspecified vectors to the (1) LoadImage or (2) LoadImageEx function in the WESPMonitor.WESPMonitorCtrl.1 control, (3) ChangePassword function in the WESPCONFIGLib.UserItem control, Connect function in the (4) WESPSerialPort.WESPSerialPortCtrl.1 or (5) WESPPLAYBACKLib.WESPPlaybackCtrl control, or (6) AddID function in the WESPCONFIGLib.IDList control or a (7) long string to the second argument to the ConnectEx3 function in the WESPPLAYBACKLib.WESPPlaybackCtrl control.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
