Security Alert: FortiManager Vulnerability Puts Networks at Risk

Security Alert: FortiManager Vulnerability Puts Networks at Risk

Fortinet recently issued a critical advisory for a severe FortiManager vulnerability affecting their FortiManager product. Identified as CVE-2024-47575, this vulnerability has a high severity score of 9.8 (out of 10) and poses a significant risk. If left unpatched, it allows remote attackers to bypass authentication and execute malicious commands on affected systems. The vulnerability impacts various versions of FortiManager, including FortiManager Cloud, and can be exploited via the FortiGate to FortiManager (FGFM) protocol.

What Happened?

On October 13, 2024, security researcher Kevin Beaumont reported this vulnerability, nicknamed "FortiJump." It involves exploiting a flaw that allows unauthorized users to execute commands by sending specially crafted requests to FortiManager. The implications of this are severe, with the potential for attackers to gain full control over the compromised system and any connected devices.

A scan of the internet revealed that nearly 60,000 devices may be exposed to this vulnerability, raising concerns for organizations using Fortinet products.

Why Should You Be Concerned?

FortiManager is widely used for managing FortiGate firewalls, making this vulnerability particularly risky. If an attacker successfully exploits it, they could:

1. Execute Unauthorized Commands:

Attackers could gain the ability to run commands within FortiManager without permission.

2. Steal Sensitive Data:

Critical information such as IP addresses, credentials, and network configurations could be accessed.

3. Deploy Malware or Ransomware:

Compromised systems could be used to spread malware or ransomware across the network.

4. Launch Further Attacks:

Connected FortiGate devices could become entry points for additional supply chain attacks.

Given the widespread use of Fortinet products, this vulnerability poses a substantial risk to both organizations and their customers.

Recommendations: How to Protect Your Systems

Fortinet has released patches to address this vulnerability in several FortiManager versions: FortiManager 7.6.0, FortiManager 7.4.0 through 7.4.4, FortiManager 7.2.0 through 7.2.7, FortiManager 7.0.0 through 7.0.12, FortiManager 6.4.0 through 6.4.14, FortiManager 6.2.0 through 6.2.12, FortiManager Cloud 7.4.1 through 7.4.4, FortiManager Cloud 7.2 (all versions), FortiManager Cloud 7.0 (all versions), FortiManager Cloud 6.4 (all versions)

We strongly advise all affected organizations to take immediate action by following these recommendations:

1. Apply Patches Immediately:

Ensure all FortiManager devices are updated to the latest versions to eliminate the risk.

2. Implement Workarounds:

If patching is not immediately possible, Fortinet has provided these temporary measures to reduce exposure:

  • Block Unknown Devices: Use the set fgfm-deny-unknown enable command to prevent unknown devices from connecting to FortiManager.
  • Use Custom SSL Certificates: Set up custom certificates for secure SSL tunneling between FortiGate and FortiManager.
  • Establish an IP Allowlist: Restrict access to FortiManager by creating a trusted list of IP addresses.
3. Establish an IP Allowlist:

Fortinet has published a list of IoCs related to this vulnerability. Review their report and closely monitor your systems for any unusual activity.

Current Exploitation Status

Attackers are actively exploiting this vulnerability, stealing sensitive information from FortiManager servers, including IPs, credentials, and configurations. This could lead to further attacks targeting FortiGate devices.
