|---|
| Mô tả | A Local File Inclusion (LFI) vulnerability was discovered in the Leave Application System in PHP and SQLite3 developed by oretnom23.
The vulnerability exists because the application loads pages dynamically using a user-controlled parameter without proper validation.
The vulnerable code is:
$page = $_GET['page'] ?? 'home';
include($page.".php");
An attacker can manipulate the "page" parameter to include unintended files.
Using the PHP filter wrapper, attackers can read sensitive source code files.
Example payload:
?page=php://filter/convert.base64-encode/resource=index
This payload returns the Base64 encoded source code of the file.
The encoded data can be decoded using:
echo "BASE64CODE" | base64 -d
This reveals sensitive server-side source code including database connection files and authentication logic.
An attacker may use this information to further compromise the application. |
