漏洞描述信息
在D-Link DCS-1100和DCS-1130设备上发现了一个问题。该设备在UDP端口5978上运行了一个自定义的进程，称为“dldps2121”，并监听255.255.255.255的广播包。这个进程处理了自定义的D-Link UDP协议，使D-Link移动应用程序和桌面应用程序能够发现本地网络中的D-Link设备。二进制处理从“main”函数中收到的任何设备发送的UDP包。该函数的一个路径指向处理 packets 的代码块，该代码块执行无边界复制操作，可能导致缓冲区溢出。Dlink 创建的自定义协议遵循以下模式：Packetlen, Packet 类型； M=设备或广播MAC地址； D=设备类型；C=base64编码命令字符串；test=1111。在地址函数中，从地址0x0000DBF8开始处理整个UDP包，并使用地址0x0000DC88的strcpy函数进行不安全的复制。这使得在1060个字符后控制PC寄存器，并导致代码执行。任何进程，包括在手机上或桌面上的攻击进程，都可以启动相同的通信方式，这使设备上的第三方应用程序在不进行任何身份验证的情况下执行设备上的指令。

漏洞描述信息
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
漏洞描述信息
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。
