## Key facts

- **Exploitation phase:** Background Noise. Continuous low-level scanning or exploitation attempts are observed, mostly opportunistic and automated.
- **CVSS score:** 7.7
- **Public exploit available:** Yes
- **Affected products:** Fortinet FortiWeb
- **Weaknesses:** CWE-233 (Improper Handling of Parameters)
- **Tags:** enterprise_software, firewall

## Description

A improper handling of parameters in Fortinet FortiWeb versions 7.6.3 and below, versions 7.4.7 and below, versions 7.2.10 and below, and 7.0.10 and below may allow an unauthenticated remote attacker with non-public information pertaining to the device and targeted user to gain admin privileges on the device via a specially crafted request.

## CrowdSec analysis

[CVE-2025-52970](https://euvd.enisa.europa.eu/vulnerability/CVE-2025-52970) is a vulnerability in Fortinet FortiWeb that stems from improper parameter handling, potentially allowing unauthenticated remote attackers with certain non-public information to escalate privileges and gain administrative access. Exploiting this flaw could enable attackers to take full control of affected FortiWeb devices, leading to significant risks such as data compromise, configuration tampering, or service disruption.

CrowdSec has been tracking this vulnerability and its exploits since 3rd of September 2025.

CrowdSec network data shows that most actors exploiting CVE-2025-52970 rely on broad, untargeted scans with minimal filtering. The activity is largely automated and opportunistic in nature.
Data from the CrowdSec community also indicates a gradual decrease in attacks targeting CVE-2025-52970. While still present in the wild, exploitation levels have dropped noticeably week-over-week. This may signal that the vulnerability is becoming less relevant or that defenses are improving fast enough for attackers to lose interest.

Attackers exploit the `/api/fabric/device/status` endpoint by injecting SQL commands via the `Authorization` header, which can lead to authentication bypass and remote code execution. Subsequent exploitation stages may involve writing a webshell to `/cgi-bin/x.cgi` and triggering it with crafted requests.
