Trend Micro Deep Security Agent: Insufficient Use of Symbolic Constants
CVE-2024-36358 is a high-severity insufficient use of symbolic constants vulnerability in Trend Micro Deep Security Agent from Trend Micro, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user.
