CVE-2024-58104 is a vulnerability identified in the Trend Micro Apex One Security Agent Plug-in User Interface Manager, specifically affecting version 2019 (14.0). The flaw allows a local attacker who already has the ability to execute low-privileged code on the target system to bypass existing security mechanisms and execute arbitrary code with elevated privileges. This vulnerability is classified under CWE-269, which relates to improper privilege management, indicating that the component fails to enforce proper access controls. The CVSS v3.1 base score is 7.3, reflecting a high severity due to the potential for complete compromise of confidentiality, integrity, and availability of the affected system. The attack vector is local (AV:L), requiring low privileges (PR:L) and user interaction (UI:R), with low attack complexity (AC:L). The vulnerability scope is unchanged (S:U), meaning the impact is limited to the vulnerable component's privileges. No public exploits have been reported, and no patches have been released at the time of publication. The vulnerability could enable attackers to escalate privileges and execute arbitrary code, potentially leading to full system compromise if combined with other attack vectors. Trend Micro Apex One is widely used in enterprise environments for endpoint security, making this vulnerability significant for organizations relying on this product for protection.

The potential impact of CVE-2024-58104 is substantial for organizations using Trend Micro Apex One 2019 (14.0). Successful exploitation allows an attacker with limited local access to escalate privileges and execute arbitrary code, potentially leading to full system compromise. This can result in unauthorized access to sensitive data (confidentiality breach), unauthorized modification or deletion of data (integrity breach), and disruption or denial of security services (availability breach). Enterprises relying on Apex One for endpoint protection may find their defenses bypassed, increasing the risk of further malware infections or lateral movement within networks. The requirement for local access and user interaction limits remote exploitation but does not eliminate risk, especially in environments where insider threats or compromised user accounts exist. The absence of known exploits in the wild currently reduces immediate risk but underscores the importance of proactive mitigation. The vulnerability could be leveraged in targeted attacks against high-value assets, particularly in sectors with stringent security requirements such as finance, healthcare, and government.

To mitigate CVE-2024-58104 effectively, organizations should implement the following specific measures: 1) Restrict local user permissions rigorously to minimize the ability of low-privileged users to execute arbitrary code; enforce the principle of least privilege across all endpoints. 2) Employ application whitelisting and endpoint detection and response (EDR) solutions to monitor and block suspicious local code execution attempts. 3) Harden system configurations to reduce attack surface, including disabling unnecessary local accounts and services. 4) Monitor logs and security alerts for unusual activities related to the Trend Micro Apex One Security Agent Plug-in User Interface Manager. 5) Prepare for timely deployment of official patches or updates from Trend Micro once released; subscribe to vendor advisories for immediate notification. 6) Conduct user awareness training to reduce risky behaviors that could facilitate local code execution or social engineering. 7) Consider network segmentation to limit lateral movement if a local compromise occurs. These steps go beyond generic advice by focusing on controlling local execution capabilities and proactive monitoring specific to the affected component.
