Vulnerability Description
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 processing of packets which does an unbounded copy operation which allows to overflow the buffer. The custom protocol created by Dlink 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 We can see at address function starting at address 0x0000DBF8 handles the entire UDP packet and performs an insecure copy using strcpy function at address 0x0000DC88. This results in overflowing the stack pointer after 1060 characters and thus allows to control the PC register and results in code execution. 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.

D-Link DCS-1100和D-Link DCS-1130 缓冲区错误漏洞
来源: 中国国家信息安全漏洞库 CNNVD
Vulnerability Description
D-Link DCS-1100和D-Link DCS-1130都是中国台湾友讯（D-Link）公司的一款网络摄像机。 D-Link DCS-1100和DCS-1130中存在缓冲区错误漏洞。该漏洞源于网络系统或产品在内存上执行操作时，未正确验证数据边界，导致向关联的其他内存位置上执行了错误的读写操作。攻击者可利用该漏洞导致缓冲区溢出或堆溢出等。
