Vulnerability Details

CVE-2022-23619Installer Uncontrolled Search Path Element Local Privilege Escalation Vulnerability 
CVSSv3: 6.5: AV:L/AC:L/PR:H/UI:R/S:U/C:H/I:H/A:H
An installer search patch element vulnerability in Trend Micro Portable Security 3.0 and 2.0 could allow a local attacker to place an arbitrarily generated DLL file in an installer folder to elevate local privileges.

Please note: an attacker must first obtain the ability to execute high-privileged code on the target system in order to exploit this vulnerability.


Mitigating Factors

Exploiting these type of vulnerabilities generally require that an attacker has access (physical or remote) to a vulnerable machine. In addition to timely application of patches and updated solutions, customers are also advised to review remote access to critical systems and ensure policies and perimeter security is up-to-date.

However, even though an exploit may require several specific conditions to be met, Trend Micro strongly encourages customers to update to the latest builds as soon as possible.
