What is CVE-2024-55591?

CVE-2024-55591 is a critical security vulnerability identified in Fortinet's FortiOS and FortiProxy software, specifically versions 7.0.0 through 7.0.16 and 7.0.0 through 7.0.19, as well as 7.2.0 through 7.2.12. This vulnerability falls under the category of Authentication Bypass Using an Alternate Path or Channel (CWE-288). It allows remote attackers to bypass standard authentication mechanisms and gain super-admin privileges by sending specially crafted requests to the Node.js websocket module integrated within these systems.

The implications of this vulnerability can be severe for organizations that rely on these Fortinet products for their network security infrastructure. Attackers who successfully exploit CVE-2024-55591 can manipulate the system's operations, create unauthorized admin accounts, and exert full control over the affected devices. This could lead to unauthorized access to sensitive data, alteration of configurations, or even complete system compromise, significantly endangering the confidentiality, integrity, and availability of an organization's critical systems and data.

Potential impact of CVE-2024-55591

  1. Unauthorized Access to Sensitive Systems: Exploitation of this vulnerability enables an attacker to elevate their privileges to super-admin status, allowing them to gain access to critical systems, sensitive information, and command over security policies.

  2. Creation of Backdoored Accounts: Attackers can create additional privileged accounts with misleading names to maintain persistence within the network, enabling further exploitation and making it difficult for organizations to detect the breach.

  3. Facilitation of Additional Attacks: With full control over compromised Fortinet devices, attackers can expand their reach within the victim's network, allowing them to execute lateral movement towards other high-value targets, conduct data exfiltration, or deploy additional malware, leading to extensive operational setbacks and potential financial loss.
