Trend Micro Apex Central: Improper Control of Filename for Include/Require Statement in PHP Program
CVE-2023-52325 is a high-severity improper control of filename for include/require statement in PHP program vulnerability in Trend Micro Apex Central from Trend Micro, with a CVSS 3.1 base score of 7.5 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 8.0.0.6570 as the first without the flaw, so updating Trend Micro Apex Central to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 4.54% chance of exploitation within 30 days, which is in the top 8.29% of all scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Trend Micro Apex Central to 8.0.0.6570 or a later version.

Official description
A local file inclusion vulnerability in one of Trend Micro Apex Central's widgets could allow a remote attacker to execute arbitrary code on affected installations. Please note: this vulnerability must be used in conjunction with another one to exploit an affected system. In addition, an attacker must first obtain a valid set of credentials on target system in order to exploit this vulnerability.

The underlying weakness: Improper Control of Filename for Include/Require Statement in PHP Program
The PHP application receives input from an upstream component, but it does not restrict or incorrectly restricts the input before its usage in require, include, or similar functions.
How developers prevent this class of flaw
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
- When the set of acceptable objects, such as filenames or URLs, is limited or known, create a mapping from a set of fixed input values (such as numeric IDs) to the actual filenames or URLs, and reject all other inputs. For example, ID 1 could map to inbox.txt and ID 2 could map to profile.txt. Features such as the ESAPI AccessReferenceMap provide this capability.
- For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
