CVE-2024-51503 — Trendmicro Deep Security Agent security vulnerability

High CVSS 8.8

A security agent manual scan command injection vulnerability in the Trend Micro Deep Security 20 Agent could allow an attacker to escalate privileges and execute arbitrary code on an affected machine. In certain circumstances, attackers that have legitimate access to the domain may be able to remotely inject commands to other machines in the same domain. Please note: an attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability locally and must have domain user privileges to affect other machines.

Command, code, expression, and template injection

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace untrusted values to process execution, interpreters, evaluators, template engines, dynamic imports, and administrative scripting features.
  • Determine whether the affected path is reachable across each trust boundary and which service account or host privilege it inherits.
  • Review configuration for optional execution features, unsafe compatibility modes, and shell invocation.

Remediate safely

  • Replace string-built commands or evaluated code with fixed operations and structured argument APIs that do not invoke a shell.
  • Use strict allowlists for operation identifiers and reject unexpected input before it reaches any interpreter.
  • Update the affected component and add inert regression tests covering metacharacters, encoding variants, and alternate request paths.
