CVE-2025-57741 is a vulnerability classified under CWE-732 (Incorrect Permission Assignment for Critical Resource) affecting Fortinet's FortiClientMac software versions 7.0.0, 7.2.0 through 7.2.11, and 7.4.0 through 7.4.3. The vulnerability allows a local attacker to hijack LaunchDaemons due to improper permission settings on critical system resources. LaunchDaemons on macOS run with elevated privileges and are used to start system or application services. By exploiting this misconfiguration, an attacker with limited user privileges can replace or manipulate the LaunchDaemon configuration or executable, causing arbitrary code or commands to run with higher privileges, effectively escalating their access rights on the system. The CVSS v3.1 score of 7.0 reflects a high severity, with attack vector local (AV:L), low attack complexity (AC:L), requiring low privileges (PR:L), and no user interaction (UI:N). The impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H), indicating that successful exploitation could lead to full system compromise. Although no known exploits are currently reported in the wild, the vulnerability is publicly disclosed and should be addressed promptly. The vulnerability affects multiple major FortiClientMac versions, indicating a broad impact on users of this endpoint security product on macOS platforms.

The impact of CVE-2025-57741 is significant for organizations using FortiClientMac on macOS devices. Successful exploitation allows a local attacker to gain elevated privileges, potentially leading to full system compromise. This can result in unauthorized access to sensitive data, disruption of security controls, and the ability to install persistent malware or backdoors. The high impact on confidentiality, integrity, and availability means that attackers could exfiltrate data, modify or delete critical files, or disrupt system operations. In enterprise environments, this could undermine endpoint security, facilitate lateral movement, and compromise broader network security. The vulnerability is particularly concerning in organizations with shared or multi-user macOS systems, or where endpoint security is critical for regulatory compliance and threat defense. Although exploitation requires local access, the ease of privilege escalation makes it a valuable attack vector for insiders or attackers who have gained initial foothold through other means.

To mitigate CVE-2025-57741, organizations should immediately upgrade FortiClientMac to the latest patched versions once available from Fortinet. Until patches are applied, restrict local user permissions to the minimum necessary and monitor for suspicious modifications to LaunchDaemon configurations or binaries. Implement strict file system permissions and integrity monitoring on LaunchDaemon directories (/Library/LaunchDaemons and /System/Library/LaunchDaemons). Employ endpoint detection and response (EDR) solutions capable of detecting anomalous process launches or privilege escalations. Conduct regular audits of installed software versions and privilege assignments on macOS endpoints. Educate users about the risks of local privilege escalation and enforce policies that limit local administrative access. Additionally, consider isolating critical macOS systems and applying network segmentation to limit the impact of potential compromises. Finally, maintain robust incident response plans to quickly address any detected exploitation attempts.
