Description Preview

CVE-2023-1047 affects TechPowerUp RealTemp version 3.7.0.0, specifically in the WinRing0x64.sys library component. This critical vulnerability stems from improper initialization in the kernel driver, which could potentially allow local attackers to elevate privileges or execute arbitrary code with kernel-level permissions. The vulnerability has been publicly disclosed with proof-of-concept code available, increasing the risk of exploitation. This issue is particularly concerning as RealTemp is a popular hardware monitoring utility used to measure CPU temperature, and its kernel driver operates with high privileges.

Overview

The vulnerability in TechPowerUp RealTemp 3.7.0.0 involves the WinRing0x64.sys kernel driver that provides low-level hardware access capabilities. The driver contains improper initialization flaws that could be exploited by a local attacker to gain elevated system privileges. The issue is particularly dangerous because:

  1. The vulnerability has been publicly disclosed with exploit code available
  2. The affected driver runs with kernel-level privileges
  3. RealTemp is widely used for hardware monitoring on Windows systems
  4. Successful exploitation could lead to complete system compromise

Remediation

To mitigate this vulnerability, the following actions are recommended:

  1. Update to a newer version of RealTemp if available that addresses this vulnerability
  2. If no patch is available, consider uninstalling RealTemp 3.7.0.0 or disabling the WinRing0x64.sys driver when not in use
  3. Implement the principle of least privilege by restricting which users can access the affected software
  4. Monitor system activities for potential exploitation attempts
  5. Consider using alternative hardware monitoring tools that do not contain this vulnerability
  6. Apply standard security practices such as keeping systems updated and using endpoint protection solutions
