Trend Micro Deep Security: Improper Neutralization of Special Elements used in a Command
CVE-2024-51503 is a high-severity improper neutralization of special elements used in a command vulnerability in Trend Micro Deep Security from Trend Micro, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists version 20.0.1-21510 as the first without the flaw, so updating Trend Micro Deep Security to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 3.97% chance of exploitation within 30 days, which is in the top 9.36% of all scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Trend Micro Deep Security to 20.0.1-21510 or a later version.
- Read the advisory on success.trendmicro.com for workarounds and exact fixed builds.

Official description
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.

The underlying weakness: Improper Neutralization of Special Elements used in a Command
The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.
How developers prevent this class of flaw
- If at all possible, use library calls rather than external processes to recreate the desired functionality.
- If possible, ensure that all external commands called from the program are statically created.
- Run time: Run time policy enforcement may be used in an allowlist fashion to prevent use of any non-sanctioned commands.
