CVE-2024-50569 is a vulnerability classified as an OS command injection affecting Fortinet FortiWeb versions 7.0.0 through 7.6.0. The flaw stems from improper neutralization of special elements in user-supplied input that is used in OS command execution contexts within the FortiWeb appliance. This improper sanitization allows an attacker with high privileges to craft input that injects and executes arbitrary OS commands on the underlying system. The vulnerability requires network access (AV:N), high attack complexity (AC:H), and privileges (PR:H), but does not require user interaction (UI:N). The scope is unchanged (S:U), and the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H). The CVSS vector reflects partial exploitability and significant impact, resulting in a medium severity rating with a CVSS score of 6.3. No public exploits are known, but the potential for full system compromise exists if exploited. FortiWeb is a widely used web application firewall product deployed globally to protect web applications from attacks, making this vulnerability critical to address. The lack of available patches at the time of disclosure necessitates immediate risk mitigation through access restriction and monitoring.

If exploited, this vulnerability could allow attackers to execute arbitrary OS commands on FortiWeb appliances, potentially leading to full compromise of the device. This could result in unauthorized access to sensitive data, disruption of web application firewall services, and pivoting into internal networks. The integrity of security policies enforced by FortiWeb could be undermined, allowing malicious traffic to bypass protections. Availability could be impacted if attackers disrupt or disable the appliance. Organizations relying on FortiWeb for critical web application security may face significant operational and reputational damage. The requirement for high privileges limits the attack surface but insider threats or compromised credentials could facilitate exploitation. The absence of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits post-disclosure.

1. Immediately restrict network access to FortiWeb management interfaces to trusted administrators only, using network segmentation and firewall rules. 2. Enforce strong authentication and privilege management to minimize the number of users with high privileges on FortiWeb devices. 3. Monitor logs and network traffic for unusual command execution patterns or unauthorized access attempts. 4. Apply Fortinet security advisories and patches as soon as they become available for affected FortiWeb versions. 5. Consider deploying additional layers of security such as endpoint detection and response (EDR) on management workstations to detect potential credential compromise. 6. Conduct regular security audits and vulnerability assessments on FortiWeb appliances to identify and remediate configuration weaknesses. 7. Implement strict input validation and sanitization policies where possible in custom integrations with FortiWeb to reduce injection risks. 8. Prepare incident response plans specifically addressing potential FortiWeb compromise scenarios.
