CVE-2024-45324
CVE-2024-45324 is a critical format string vulnerability affecting multiple Fortinet products. This flaw allows a privileged attacker to inject malicious code by exploiting specially crafted HTTP/HTTPS commands. The affected products include versions of FortiOS, FortiProxy, FortiPAM, FortiSRA, and FortiWeb. Although the CVSS score is low, the SOCRadar Vulnerability Risk Score (SVRS) for CVE-2024-45324 is 36, indicating a moderate level of risk that should be monitored. Due to the CWE-134 designation, successful exploitation could lead to unauthorized code execution and compromise of the affected systems. Given that this vulnerability is tagged as "In The Wild," organizations using these Fortinet products should promptly investigate and apply available patches or mitigations to prevent potential exploitation and maintain the security of their infrastructure. The ability of an attacker to execute commands makes this a significant security concern.
Description
CVE-2024-45324 is a format string vulnerability (CWE-134) affecting multiple Fortinet products including FortiOS, FortiProxy, FortiPAM, FortiSRA, and FortiWeb. This vulnerability allows a privileged attacker to execute unauthorized code or commands by exploiting specially crafted HTTP or HTTPS commands. The SOCRadar Vulnerability Risk Score (SVRS) is 36, indicating a moderate risk. However, it's important to note that this vulnerability is being actively exploited in the wild.
Key Insights
-
Format String Vulnerability: The root cause is a format string vulnerability. Attackers can manipulate input strings that are used in format functions, leading to arbitrary code execution if not properly sanitized.
-
Wide Range of Affected Products: This vulnerability affects a broad spectrum of Fortinet products, including firewalls, proxies, PAM solutions, SRA solutions, and web application firewalls. This widespread impact increases the potential attack surface for adversaries.
-
Privileged Access Required: Although requiring privileged access initially limits the attack surface, once gained, attackers can execute arbitrary code or commands, leading to significant compromise.
-
Actively Exploited in the Wild: Because this vulnerability is used in the wild, this significantly elevates the urgency for remediation, irrespective of the SVRS score.
Mitigation Strategies
-
Immediate Patching: Apply the latest patches provided by Fortinet for all affected products (FortiOS, FortiProxy, FortiPAM, FortiSRA, FortiWeb). Prioritize patching based on the organization's asset inventory and the criticality of each system.
-
Input Validation and Sanitization: Implement stringent input validation and sanitization measures for HTTP and HTTPS commands. Employ secure coding practices to prevent format string vulnerabilities.
-
Network Segmentation: Implement network segmentation to limit the potential impact of a successful exploit. If a system is compromised, segmentation can prevent the attacker from moving laterally to other critical assets.
-
Privilege Management: Review and enforce strict privilege management policies. Minimize the number of users and accounts with privileged access to reduce the attack surface. Regularly audit privileged accounts for suspicious activity.
