TSplus Remote Work 16.0.0.0 has weak permissions for .exe, .js, and .html files under the %PROGRAMFILES(X86)%TSplus-RemoteWorkClientswww folder. This may enable privilege escalation if a different local user modifies a file. NOTE: CVE-2023-31067 and CVE-2023-31068 are only about the TSplus Remote Access product, not the TSplus Remote Work product.

Weakness

During installation, installed file permissions are set to allow anyone to modify those files.

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.
