CVE-2024-47193 is a vulnerability identified in WithSecure's security products for macOS, specifically Elements Agent for Mac versions prior to 24.3, MDR before 24.3, and Elements Client Security for Mac before 16.10. The flaw enables a remote denial of service (DoS) attack, where an attacker with low privileges can cause the security software to crash or become unresponsive, thereby disrupting its protective functions. The CVSS 3.1 base score is 5.5, indicating a medium severity level. The vector string AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H indicates that the attack requires local access, low attack complexity, and low privileges, with no user interaction needed. The scope remains unchanged, and the impact is solely on availability, with no confidentiality or integrity loss. The vulnerability likely arises from improper handling of certain inputs or requests within the software, leading to resource exhaustion or application failure. No public exploit code or active exploitation has been reported, but the risk remains for environments where attackers can gain local access. The vulnerability affects the availability of critical endpoint protection components on Mac systems, potentially leaving them exposed to other threats if the security agent is incapacitated.

The primary impact of CVE-2024-47193 is the disruption of endpoint security services on affected Mac systems, resulting in a denial of service. This can lead to temporary loss of protection, increasing the risk of subsequent attacks such as malware infections or unauthorized access. Organizations relying on WithSecure's Mac security products may experience interruptions in security monitoring and response capabilities. While the vulnerability does not expose sensitive data or allow privilege escalation, the loss of availability can degrade overall security posture. Enterprises with large Mac deployments, especially those in regulated industries or with high security requirements, may face operational challenges and increased risk exposure during exploitation. The requirement for local access limits remote exploitation, but insider threats or attackers who have gained foothold on endpoints could leverage this vulnerability to disable security controls. The absence of known exploits reduces immediate risk but does not eliminate the potential for future attacks.

To mitigate CVE-2024-47193, organizations should promptly update all affected WithSecure Elements Agent for Mac, MDR, and Elements Client Security for Mac installations to versions 24.3 or later (for Elements Agent and MDR) and 16.10 or later (for Elements Client Security). In environments where immediate patching is not feasible, restrict local access to Mac endpoints by enforcing strict access controls and monitoring for unusual activity. Employ endpoint detection and response (EDR) solutions to detect attempts to disrupt security agents. Regularly audit and harden user privileges to minimize the risk of low-privilege attackers exploiting this vulnerability. Additionally, maintain comprehensive logging and alerting to identify potential denial of service attempts against security software. Coordinate with WithSecure support for any available workarounds or additional guidance. Finally, incorporate this vulnerability into incident response plans to ensure rapid recovery if exploitation occurs.
