CVE-2025-24150 is a command injection vulnerability identified in Apple Safari's Web Inspector tool, fixed in Safari 18.3, iOS 18.3, iPadOS 18.3, and macOS Sequoia 15.3. The vulnerability stems from improper handling when copying URLs from the Web Inspector, which can lead to execution of arbitrary commands on the host system. This flaw is categorized under CWE-77, indicating improper neutralization of special elements in OS commands. The CVSS v3.1 score of 8.8 reflects a high-severity issue with network attack vector, low attack complexity, requiring privileges but no user interaction, and impacting confidentiality, integrity, and availability. An attacker with limited privileges who can access Web Inspector could exploit this vulnerability to execute commands, potentially leading to full system compromise. Although no public exploits are known, the vulnerability poses a significant risk especially in development environments where Web Inspector is used. The issue was addressed by improving file handling and sanitization in the affected Safari versions. Due to the nature of the vulnerability, it could be leveraged for privilege escalation or lateral movement within networks.

The vulnerability allows an attacker with limited privileges to execute arbitrary commands on affected systems, threatening confidentiality by potentially exposing sensitive data, integrity by altering system or application behavior, and availability by disrupting services or causing system crashes. Organizations relying on Safari for development or debugging are particularly at risk, as Web Inspector access is required for exploitation. The flaw could be used to escalate privileges or move laterally within corporate networks, increasing the scope of compromise. Given the widespread use of Apple devices globally, especially in enterprise and creative sectors, the impact could be substantial if exploited. The absence of required user interaction lowers the barrier for exploitation once an attacker has limited access, increasing urgency for mitigation.

1. Immediately update all Apple Safari browsers and affected operating systems (iOS, iPadOS, macOS) to versions 18.3 or later where the vulnerability is patched. 2. Restrict access to Web Inspector features to trusted users only, ideally disabling it in production or sensitive environments. 3. Implement strict privilege separation and limit user permissions to reduce the risk of exploitation by low-privilege users. 4. Monitor system logs and command execution patterns for anomalies indicative of command injection attempts. 5. Employ endpoint detection and response (EDR) solutions capable of detecting suspicious command execution originating from Safari processes. 6. Educate developers and IT staff about the risks of using debugging tools like Web Inspector in unsecured contexts. 7. Consider network segmentation to isolate development environments from critical infrastructure to limit lateral movement opportunities.
