What is CVE-2024-55591?
CVE-2024-55591 is a security vulnerability found in Fortinet's FortiOS and FortiProxy platforms, which are designed to provide advanced network security services. This flaw allows remote attackers to exploit the Node.js websocket module by sending specially crafted requests, leading to an authentication bypass. If successfully exploited, the vulnerability grants attackers super-admin privileges, posing a significant threat to the integrity and security of affected systems within an organization.
Technical Details
The vulnerability falls under the category of Authentication Bypass Using an Alternate Path or Channel (CWE-288). It affects specific versions of FortiOS (7.0.0 through 7.0.16) and FortiProxy (7.0.0 through 7.0.19 and 7.2.0 through 7.2.12). Attackers can manipulate the websocket communication to bypass security measures, thereby gaining unauthorized access and control over the affected systems. This vulnerability is particularly critical due to the potential for highly privileged access offered to attackers.
Potential impact of CVE-2024-55591
-
Unauthorized Access: The ability for attackers to gain super-admin privileges means they can access sensitive data, modify system configurations, and potentially disrupt service operations.
-
Data Breach Risks: With elevated privileges, an attacker could exfiltrate or leak sensitive information, leading to severe reputational damage and legal repercussions for the affected organization.
-
System Compromise: The exploitation of this vulnerability could allow attackers to install malware or conduct further attacks within the network, increasing the risk of ransomware deployment and other malicious activities.
