Can you explain this vulnerability to me?
This vulnerability is an improper access control issue in the TeamViewer Full and Host clients (Windows, macOS, Linux) before version 15.74.5. It allows an authenticated user in a remote session to bypass additional access controls configured with the “Allow after confirmation” setting. Essentially, even though local confirmation is expected before certain actions, an attacker who is already authenticated via ID/password, Session Link, or Easy Access can exploit this flaw to gain unauthorized access without that local confirmation.
How can this vulnerability impact me? :
The impact of this vulnerability is that an authenticated remote user could gain unauthorized access to a system or perform actions without the expected local confirmation. This could lead to a compromise of confidentiality, integrity, and availability of the affected system, as indicated by the CVSS score which rates the impact as high in these areas.
