Overview
The CVE-2025-52970 is a severe vulnerability found in specific versions of the Fortinet FortiWeb system. This vulnerability affects versions 7.6.3 and below, versions 7.4.7 and below, versions 7.2.10 and below, and 7.0.10 and below. This vulnerability is critical because it allows an unauthenticated remote attacker, armed with non-public information about the device and targeted user, to gain admin privileges on the device via a specially crafted request.
This vulnerability poses a significant risk to any organization using the affected versions of Fortinet FortiWeb, as it could potentially lead to a full system compromise or data leakage. Therefore, organizations need to take immediate action to mitigate this risk.

How the Exploit Works
This vulnerability stems from the improper handling of parameters within the Fortinet FortiWeb system. An attacker can exploit this weakness by crafting a specific request containing malicious data. If this request is processed by the Fortinet FortiWeb system, the attacker could potentially manipulate the system into granting them admin privileges.
This exploit does not require any pre-existing privileges or user interaction, making it a grave risk as it allows attackers to gain unauthorized access to systems and data.
Conceptual Example Code
Here is a conceptual example of how the vulnerability might be exploited:
POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"device_info": "non-public information",
"user_target": "targeted user",
"admin_request": "specially crafted request"
}In this example, the attacker sends a POST request with a malicious payload containing non-public information about the device, the targeted user, and a specially crafted request that tricks the system into granting them admin privileges.
