[原文]Buffer overflow in the cmdIS.DLL plugin for AN HTTPD Server 1.42n allows remote attackers to execute arbitrary code via an HTTP request with a long User-Agent header.


[CNNVD]AN HTTPD CMDIS.DLL远程缓冲区溢出漏洞(CNNVD-200505-773)

        AN HTTPD Server是一款Windows 95/98/Me/NT/2000/XP平台下的web服务程序。
        AN HTTPD中存在远程缓冲区溢出漏洞。漏洞的起因是调用GetEnvironmentStrings函数的cmdIS.DLL将环境变量拷贝至固定大小的进程缓冲区中。
        攻击者可以创建包含有过多数据做为受影响HTTP首部值的畸形HTTP GET命令来触发溢出,可能导致执行任意代码,允许攻击者非授权访问Web Server。

15361
AN HTTPD Server cmdIS.DLL user-agent Field Remote Overflow
Remote / Network Access Input Manipulation
Loss of Integrity

- 漏洞描述

A remote overflow exists in AN HTTPD Server. The server fails to check the bounds of the user-agent field resulting in a buffer overflow. With a specially crafted request, an attacker can cause the execution of arbitrary scripts resulting in a loss of integrity.

- 受影响的程序版本

AN AN-HTTPd 1.42 n

- 漏洞讨论

AN HTTPD is reported prone to a remote buffer overflow vulnerability.

Specifically, the issue presents itself in 'cmdIS.DLL' which calls the 'GetEnvironmentStrings' function to copy environment variables into a finite sized process buffer.

The attacker can issue a malformed HTTP GET command including excessive data as a value for an affected HTTP header to trigger the overflow. This can lead to arbitrary code execution, allowing the attacker to gain unauthorized access in the context of the Web server.

AN HTTPD 1.42n is reported vulnerable, however, it is possible that other versions are affected as well.

- 漏洞利用

The following proof of concept is available:
GET /scripts/cmdIS.dll/cgi-bin/test.bat HTTP/1.0
user-agent: aaaaaaaaaaaaaaaaaaaaaa [approx 8300 characters] aaaaaaaaaaaaaaaaaaaa...

Currently we are not aware of any exploits for this issue. If you feel we are in error or are aware of more recent information, please mail us at: vuldb@securityfocus.com <mailto:vuldb@securityfocus.com>.
