[原文]Buffer overflow in MyWeb 3.3 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long HTTP GET request.


[CNNVD]MyWeb HTTP Server GET请求远程缓冲区溢出漏洞(CNNVD-200412-844)

        
        MyWeb是一款小型的WEB服务程序,可用于图片、MP3、文件等共享。
        MyWeb在特殊构建的HTTP GET请求缺少充分边界检查,远程攻击者可以利用这个漏洞对WEB服务程序进行缓冲区溢出攻击,可能以进程权限在系统上执行任意指令。
        提交包含4096字节数据的HTTP GET请求,可导致MyWeb崩溃,精心构建提交数据,可能以进程权限在系统上执行任意指令。

MyWeb HTTP Server 3.3 GET Request Buffer Overflow Vulnerability (EDBID:24097)

source: http://www.securityfocus.com/bid/10303/info

A vulnerability has been reported for MyWeb HTTP server. The problem occurs due to insufficient bounds checking when handling GET requests.

As a result, an attacker may be capable of corrupting sensitive data such as a return address, and thereby effectively control the execution flow of the program. This would ultimately allow for the execution of arbitrary code. Immediate consequences of exploitation of this issue may result in denial of service.
