CVE-2023-47199: Vulnerability in Trend Micro, Inc. Trend Micro Apex One
An origin validation vulnerability in the Trend Micro Apex One security agent could allow a local attacker to escalate privileges on affected installations. Please note: an attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. This vulnerability is similar to, but not identical to, CVE-2023-47193.
AI Analysis
Technical Summary
CVE-2023-47199 is a high-severity vulnerability affecting Trend Micro Apex One 2019 (version 14.0) security agents. The flaw stems from improper origin validation within the Apex One agent, which can be exploited by a local attacker to escalate privileges on the affected system. Specifically, the vulnerability allows an attacker who already has the ability to execute code with low privileges on the target machine to elevate their privileges, potentially gaining administrative or SYSTEM-level access. This escalation can lead to full control over the endpoint, compromising confidentiality, integrity, and availability of the system. The vulnerability is categorized under CWE-346, which relates to origin validation errors that can lead to security bypasses. The CVSS v3.1 base score is 7.8, reflecting high severity, with the vector indicating local attack vector (AV:L), low attack complexity (AC:L), requiring low privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Although no known exploits are reported in the wild yet, the vulnerability's nature and impact make it a significant risk for organizations using the affected Trend Micro Apex One version. It is also noted that this vulnerability is similar but not identical to CVE-2023-47193, suggesting a pattern of origin validation issues in this product line. No patch links are currently provided, indicating that organizations must monitor vendor advisories closely for updates or mitigations.
Potential Impact
For European organizations, the impact of CVE-2023-47199 could be substantial, especially for those relying on Trend Micro Apex One 2019 for endpoint protection. Successful exploitation would allow attackers to gain elevated privileges on endpoints, potentially bypassing security controls and enabling further lateral movement, data exfiltration, or deployment of ransomware. This could compromise sensitive personal data protected under GDPR, leading to regulatory penalties and reputational damage. Critical infrastructure sectors such as finance, healthcare, and government entities in Europe, which often deploy Trend Micro solutions, could face operational disruptions and increased risk of targeted attacks. The local attack vector means that initial compromise must occur through other means (e.g., phishing, malware), but once foothold is established, this vulnerability facilitates privilege escalation, making incident containment more difficult. The high impact on confidentiality, integrity, and availability underscores the risk of full system compromise, data loss, or service outages.
Mitigation Recommendations
European organizations should take immediate steps to mitigate this vulnerability. First, they must verify if their Apex One installations are running the affected 2019 (14.0) version and prioritize upgrading to the latest version or applying vendor-provided patches once available. In the absence of patches, organizations should implement strict endpoint security hygiene: restrict local user permissions to the minimum necessary, enforce application whitelisting to prevent unauthorized code execution, and deploy endpoint detection and response (EDR) solutions to monitor for suspicious privilege escalation attempts. Network segmentation and limiting lateral movement can reduce the impact of a compromised endpoint. Additionally, organizations should conduct regular vulnerability assessments and penetration tests focusing on privilege escalation vectors. User training to prevent initial low-privilege code execution (e.g., phishing awareness) is also critical. Monitoring vendor advisories for updates on this CVE and related vulnerabilities (such as CVE-2023-47193) is essential to apply timely fixes.
