[原文]Multiple buffer overflows in WinEggDropShell remote access trojan (RAT) 1.7 allow remote attackers to execute arbitrary code via (1) a long GET request to the HTTP server, or a long (2) USER or (3) PASS command to the FTP server.


[CNNVD]WinEggDropShell多个远程缓冲区溢出漏洞(CNNVD-200512-071)

        WinEggDropShell是一款流行的支持中文的telnet类型后门程序。
        WinEggDropShell中存在多个远程溢出漏洞,远程攻击者可能利用漏洞在安装了此后门的服务器上执行任意指令。
        主要漏洞如下:
        1. FTP USER溢出
        .text:100027BD push offset aUser ; "USER"
        .text:100027C2 call _strlen
        .text:100027C7 add esp, 4
        .text:100027CA lea edi, [ebp+eax-103h]
        .text:100027D1 push edi
        .text:100027D2 push offset aS ; " "
        .text:100027D7 lea edi, [ebp+var_208]
        .text:100027DD push edi ; char *
        .text:100027DE call _sprintf ; emmmmm, ;)
        _ReceiveSocketBuffer最多能接收0x200h,但[ebp+var_208]仅为0x104h大小的缓冲区。
        2. FTP Server绕过命令
         .............
        3. HTTP GET栈溢出
         GET /A*260
        成功利用这些漏洞的攻击者可以在目标系统上执行任意代码,或导致蓝屏。
