An issue was discovered on D-Link DCS-1100 and DCS-1130 devices. The device has a custom binary called mp4ts under the /var/www/video folder. It seems that this binary dumps the HTTP VERB in the system logs. As a part of doing that it retrieves the HTTP VERB sent by the user and uses a vulnerable sprintf function at address 0x0000C3D4 in the function sub_C210 to copy the value into a string and then into a log file. Since there is no bounds check being performed on the environment variable at address 0x0000C360 this results in a stack overflow and overwrites the PC register allowing an attacker to execute buffer overflow or even a command injection attack.

Buffer Overflow vulnerability in D-Link DSR-150, DSR-150N, DSR-250, DSR-250N, DSR-500N, DSR-1000N from 3.13 to 3.17B901C allows unauthenticated users to execute remote code execution.

An issue was discovered on D-Link DCS-1100 and DCS-1130 devices. The device runs a custom daemon on UDP port 5978 which is called "dldps2121" and listens for broadcast packets sent on 255.255.255.255. This daemon handles custom D-Link UDP based protocol that allows D-Link mobile applications and desktop applications to discover D-Link devices on the local network. The binary processes the received UDP packets sent from any device in "main" function. One path in the function traverses towards a block of code that handles commands to be executed on the device. The custom protocol created by D-Link follows the following pattern: Packetlen, Type of packet; M=MAC address of device or broadcast; D=Device Type;C=base64 encoded command string;test=1111. If a packet is received with the packet type being "S" or 0x53 then the string passed in the "C" parameter is base64 decoded and then executed by passing into a System API. We can see at address 0x00009B44 that the string received in packet type subtracts 0x31 or "1" from the packet type and is compared against 0x22 or "double quotes". If that is the case, then the packet is sent towards the block of code that executes a command. Then the value stored in "C" parameter is extracted at address 0x0000A1B0. Finally, the string received is base 64 decoded and passed on to the system API at address 0x0000A2A8 as shown below. The same form of communication can be initiated by any process including an attacker process on the mobile phone or the desktop and this allows a third-party application on the device to execute commands on the device without any authentication by sending just 1 UDP packet with custom base64 encoding.

An issue was discovered on D-Link DCS-1100 and DCS-1130 devices. The device requires that a user logging into the device provide a username and password. However, the device allows D-Link apps on the mobile devices and desktop to communicate with the device without any authentication. As a part of that communication, the device uses custom version of base64 encoding to pass data back and forth between the apps and the device. However, the same form of communication can be initiated by any process including an attacker process on the mobile phone or the desktop and this allows a third party to retrieve the device's password without any authentication by sending just 1 UDP packet with custom base64 encoding. The severity of this attack is enlarged by the fact that there more than 100,000 D-Link devices out there.

Multiple D-Link devices including the DIR-850L firmware versions 1.14B07 and 2.07.B05 contain a stack-based buffer overflow vulnerability in the web administration interface HNAP service.
