Vulnerability Details

These updates resolves the following in affected versions of Trend Micro Deep Security and Vulnerability Protection:

  1. CVE-2019-9488 (CVSSv3 6.8 - AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:N/A:N):  Affected versions of Trend Micro Deep Security Manager and Vulnerability Protection are vulnerable to a XML External Entity Attack.  However, for the attack to be possible, the attacker must have root/admin access to a protected host which is authorized to communicate with the Deep Security Manager (DSM).

    Due to the seriousness of this and any vulnerabilities, customers are highly encouraged to update to the latest build as soon as possible.

    In addition to the vulnerability discovered and addressed above, another potential issue was reported and is being given a Defense in Depth (DiD) credit:

  2. *Defense in Depth (DiD) Credit: It was reported that affected versions of Trend Micro Deep Security do not have integrity checking of deployed agent files to protect against potential tampering.  Fortunately, Trend Micro Deep Security on Windows has an Agent Self-Protection mechanism to protect against the modification of agent files.  More information can be found at the Deep Security Help Center: Enable or disable agent self-protection section.

    Mitigating Factors

    Exploiting these type of vulnerabilities generally require that an attacker has access (physical or remote) to a vulnerable machine. In addition to timely application of patches and updated solutions, customers are also advised to review remote access to critical systems and ensure policies and perimeter security is up-to-date.

    However, even though an exploit may require several specific conditions to be met, Trend Micro strongly encourages customers to update to the latest builds as soon as possible.
