How the Exploit Works

The exploit works by taking advantage of the weak user role management in the GLPI software. A user without administrative privileges can manipulate the order in which the rules execute. This could potentially lead to unexpected behavior of the software, data leakage, or even a full system compromise if the rules are configured to perform critical operations.

Conceptual Example Code

An example of how this vulnerability might be exploited is illustrated below. This is a conceptual example and may not represent an actual exploit.

POST /changeRuleOrder HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"ruleId": "1001",
"newPosition": "1"
}

In this example, the attacker sends a POST request to the ‘changeRuleOrder’ endpoint, attempting to reposition a rule identified by “ruleId” to a new position in the execution order. The successful execution of this request could result in the unauthorized modification of the GLPI software’s rules execution sequence.

Recommendation

Users are strongly advised to upgrade to version 10.0.19 or later where this vulnerability has been patched. In the interim, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as temporary mitigation.
