Description

CVE-2024-52961 describes an OS Command Injection vulnerability (CWE-78) affecting Fortinet FortiSandbox. The vulnerability exists due to improper neutralization of special elements within OS commands. An authenticated attacker with at least read-only permissions can exploit this to execute unauthorized commands on the system via crafted requests. The vulnerability affects FortiSandbox versions 5.0.0, 4.4.0 through 4.4.7, 4.2.0 through 4.2.7, and before 4.0.5. The CVSS score is 8.8, indicating high severity. The SVRS score is 0, suggesting SOCRadar has not yet identified elements in social media, news, code repositories, dark/deep web data, or associations with threat actors or malware related to this vulnerability. The vulnerability is actively exploited in the wild.

Key Insights

1. Command Injection Risk: The primary threat is the ability for an attacker to execute arbitrary OS commands on the FortiSandbox appliance. This could lead to complete system compromise, data exfiltration, or use of the appliance as a pivot point for further attacks within the network.
2. Authentication Requirement: While the attacker needs to be authenticated, only read-only permissions are required. This expands the potential attack surface, as many users might have these permissions.
3. Wide Version Scope: Multiple versions of FortiSandbox are affected, indicating a potentially widespread impact on organizations using these older versions.
4. Actively Exploited: This vulnerability is actively exploited by hackers, highlighting the urgency for patching and remediation.

Mitigation Strategies

1. Immediate Patching: Upgrade Fortinet FortiSandbox to a patched version as soon as possible. Fortinet's security advisories will provide the specific versions that address this vulnerability.
2. Access Control Review: Review and restrict access to FortiSandbox, ensuring that only necessary personnel have read-only or higher permissions. Implement the principle of least privilege.
3. Network Segmentation: Segment the network to limit the potential damage an attacker can cause if they compromise the FortiSandbox. Prevent lateral movement to other critical systems.
4. Web Application Firewall (WAF) Rules: Since the attack occurs through crafted requests, organizations can implement WAF rules to filter and block malicious requests containing special elements, adding an extra layer of protection.
