## Key facts

- **Exploitation phase:** Limited Exploitation. The vulnerability is known but shows very limited attacker interest or exploitation activity.
- **CVSS score:** 9.8
- **Public exploit available:** Yes
- **Affected products:** Four-Faith F3x36
- **Weaknesses:** CWE-489 (Active Debug Code); CWE-798 (Use of Hard-coded Credentials)
- **Tags:** iot

## Description

The Four-Faith F3x36 router using firmware v2.0.0 is vulnerable to authentication bypass due to hard-coded credentials in the administrative web server. An attacker with knowledge of the credentials can gain administrative access via crafted HTTP requests. This issue appears similar to CVE-2023-32645.

## CrowdSec analysis

[CVE-2024-9643](https://euvd.enisa.europa.eu/vulnerability/CVE-2024-9643) is a critical vulnerability in the Four-Faith F3x36 router firmware v2.0.0, where hard-coded administrative credentials allow attackers to bypass authentication and gain full control of the device via crafted HTTP requests. Exploiting this flaw could enable remote attackers to access sensitive information, modify configurations, or disrupt network operations.

CrowdSec has been tracking this vulnerability and its exploits since 15th of April 2026.

Data from the CrowdSec community indicates that exploitation of CVE-2024-9643 is highly selective and intelligence-driven. Threat actors use advanced reconnaissance and carefully choose their targets, often as part of sophisticated campaigns or advanced persistent threat operations.
CrowdSec network telemetry also shows that exploitation of CVE-2024-9643 has significantly declined over the past week. Attack volumes are well below the long-term average, suggesting attackers are rapidly losing interest. The vulnerability appears to be falling out of active use across most threat landscapes.

Attackers exploit this vulnerability by sending HTTP requests with hard-coded credentials to endpoints like `/Status_Router.asp`, bypassing authentication and gaining administrative access to Four-Faith F3x36 routers.
