Description Preview

A security vulnerability exists in the USB vHub component of Teradici PCOIP Software Agent versions prior to 21.07.0. The vulnerability allows the vHub driver to accept commands from any program without proper authorization checks, potentially enabling attackers to elevate privileges by manipulating program execution flow within the driver.

Overview

The vulnerability affects the USB vHub component in Teradici PCOIP Software Agent versions prior to 21.07.0. The issue stems from insufficient validation of commands sent to the vHub driver, allowing unauthorized programs to interact with it. An attacker who successfully exploits this vulnerability could potentially execute arbitrary code with elevated privileges by altering the program execution flow within the driver. This represents a significant security risk as it could lead to complete system compromise if exploited successfully.

Remediation

To address this vulnerability, organizations should take the following actions:

  1. Update Teradici PCOIP Software Agent to version 21.07.0 or later, which contains the fix for this vulnerability.
  2. If immediate updating is not possible, consider implementing network segmentation to limit access to affected systems.
  3. Monitor systems for suspicious activities that might indicate exploitation attempts.
  4. Apply the principle of least privilege to minimize the potential impact of exploitation.
  5. Contact Teradici support for additional guidance if needed.
