[CNNVD]Pablo Software Solutions FTP Server格式串溢出漏洞(CNNVD-200211-026)

        
        Pablo Software Solutions' FTP server是一款多线程FTP服务程序,可使用在Windows操作系统上。
        Pablo FTP服务程序对用户提交的用户名缺少正确的检查,远程攻击者可以利用这个漏洞进行格式串溢出攻击,可以导致拒绝服务攻击,也可能以FTP进程的权限在系统上执行任意指令。
        Pablo FTP服务程序对用户名参数检查不够充分,攻击者如果使用恶意格式串作为用户名提交给FTP服务程序,可导致破坏堆栈内容,精心构建提交的格式串数据可以覆盖任意堆栈地址而以FTP进程权限在系统上执行任意指令。
