Title
Improper Access Control in TeamViewer clients
Summary
Improper access control in the TeamViewer Full and Host clients (Windows, macOS, Linux) prior version 15.74.5 allows an authenticated user to bypass additional access controls with “Allow after confirmation” configuration in a remote session. An exploit could result in unauthorized access prior to local confirmation. The user needs to be authenticated for the remote session via ID/password, Session Link, or Easy Access as a prerequisite to exploit this vulnerability.
