OfficeScanXG (12.0) CP 1708ReadmeWindowsNow
11.0 SP1 CP 6426ReadmeWindowsNow
Please note: this is the minimum version(s) of the patch and/or build required to address the issue. Trend Micro highly encourages customers to obtain the latest version of the product if there is a newer one available than the one listed in this bulletin.

Customers are encouraged to visit Trend Micro’s Download Center to obtain prerequisite software (such as Service Packs and other patches) before applying any of the solutions above.

Vulnerability Details

These CPs resolve multiple vulnerabilities in Trend Micro OfficeScan 11.0 and XG (12.0)* in which a remote attacker could potentially attain code execution on vulnerable installations:

  • Pre-authorization Start Remote Process
  • Information Disclosure
  • Host Header Injection
  • Unauthenticated Access Control
  • Man-in-the-Middle (MITM) Remote Code Execution
  • Memory Corruption Privilege Escalation
In addition, some additional issues were addressed that improve OfficeScan's handling of items that could potentially be abused by manipulating Image File Execution Options (IFEO) which is an OS feature, and improvement of some .php files to fend off server side request forgeries.

Due to the nature of any vulnerability, customers are highly encouraged to update to the latest build or patch as soon as possible.

*Please note that not all vulnerabilities listed above apply to both OfficeScan 11 and XG, however, it is strongly recommended that the CPs are applied to both versions to resolve any and all potential issues.

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.
