CVE-2022-44653: n/a in Trend Micro, Inc. Trend Micro Apex One
A security agent directory traversal vulnerability in Trend Micro Apex One and Apex One as a Service 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.
AI Analysis
Technical Summary
CVE-2022-44653 is a directory traversal vulnerability identified in Trend Micro Apex One, both in its On-Premise (version 14.0) and SaaS (version 14.0) deployments. This vulnerability allows a local attacker, who already has the capability to execute low-privileged code on the affected system, to escalate their privileges by exploiting improper handling of directory paths within the security agent. Specifically, the flaw relates to CWE-22 (Improper Limitation of a Pathname to a Restricted Directory), where the software fails to properly sanitize or validate directory traversal sequences, enabling an attacker to access or manipulate files outside the intended directory scope. The vulnerability does not require user interaction but does require the attacker to have local access with low privileges. The CVSS v3.1 base score is 7.8 (high severity), with vector AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, indicating that the attack vector is local, attack complexity is low, privileges required are low, no user interaction is needed, and the impact on confidentiality, integrity, and availability is high. Although no known exploits are reported in the wild, the potential for privilege escalation could allow an attacker to gain administrative control over the system, bypass security controls, and potentially move laterally within a network. This vulnerability is significant because Trend Micro Apex One is widely deployed as an endpoint security solution, and compromise of this product could undermine the security posture of affected organizations.
Potential Impact
For European organizations, the impact of this vulnerability could be substantial. Trend Micro Apex One is commonly used in enterprise environments to provide endpoint protection, malware detection, and response capabilities. Successful exploitation could allow attackers to escalate privileges from a low-privileged user context to administrative levels, potentially disabling security controls, deploying malware, or exfiltrating sensitive data. This could lead to breaches of confidentiality, integrity, and availability of critical systems. Given the high impact on all three security pillars and the prevalence of Trend Micro products in sectors such as finance, healthcare, manufacturing, and government, exploitation could disrupt operations, cause data breaches, and result in regulatory non-compliance under GDPR. Additionally, since the vulnerability requires local code execution, it could be chained with other vulnerabilities or social engineering attacks to achieve full compromise. The lack of known exploits in the wild suggests the threat is currently theoretical but should be treated proactively due to the high severity and potential for rapid exploitation once a working exploit is developed.
Mitigation Recommendations
1. Apply official patches or updates from Trend Micro as soon as they become available; monitor vendor advisories closely since no patch links were provided in the initial disclosure. 2. Restrict local code execution privileges by enforcing strict application whitelisting and endpoint privilege management to minimize the risk of low-privileged code execution. 3. Implement robust endpoint detection and response (EDR) solutions to monitor for suspicious activities indicative of privilege escalation attempts. 4. Conduct regular audits of user privileges and remove unnecessary local access rights to limit the attack surface. 5. Employ network segmentation to isolate critical systems running Apex One, reducing the impact of potential lateral movement. 6. Educate users and administrators on the risks of executing untrusted code locally and enforce policies to prevent unauthorized software installations. 7. Utilize application control features within Apex One or complementary security products to prevent exploitation of directory traversal flaws. 8. Monitor system and security logs for anomalies related to file access patterns or privilege escalations that could indicate exploitation attempts.
