How the Exploit Works<\/strong><\/p>\n

The vulnerability exists due to an insufficient security restriction within the \/Api\/TinyMce\/UploadAjax.ashx file of Lingxing ERP 2. Attackers can manipulate the File argument to upload arbitrary files to the system. No user interaction or special privileges are required to exploit this vulnerability.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

An attacker might exploit the vulnerability by sending a malicious HTTP POST request similar to the following:<\/p>\n

POST \/Api\/TinyMce\/UploadAjax.ashx HTTP\/1.1\nHost: target.example.com\nContent-Type: multipart\/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW\n------WebKitFormBoundary7MA4YWxkTrZu0gW\nContent-Disposition: form-data; name=\"File\"; filename=\"malicious_file.exe\"\nContent-Type: application\/octet-stream\n\n------WebKitFormBoundary7MA4YWxkTrZu0gW--<\/code><\/pre>\n
Mitigation<\/strong><\/p>\n
In the absence of a vendor-supplied patch, it is recommended to use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as temporary mitigation. These measures can help detect and prevent unauthorized file uploads. Users should also limit access to the affected component until a patch is available.<\/p>\n","protected":false},"excerpt":{"rendered":"
