A registry permissions vulnerability in the Trend Micro Apex One Data Loss Prevention (DLP) module could allow a local attacker with administrative credentials to bypass certain elements of the products anti-tampering mechanisms on affected installations. Please note: an attacker must first obtain administrative credentials on the target system in order to exploit this vulnerability.
Weakness
During installation, installed file permissions are set to allow anyone to modify those files.
Affected Software
| Name | Vendor | Start Version | End Version |
|---|---|---|---|
| Apex_one | Trendmicro | - (including) | - (including) |
| Apex_one | Trendmicro | 2019 (including) | 2019 (including) |
Potential Mitigations
- Compartmentalize the system to have “safe” areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
- Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
