Descriptions

An issue was discovered in TeamViewer 14.2.2558. Updating the product as a non-administrative user requires entering administrative credentials into the GUI. Subsequently, these credentials are processed in Teamviewer.exe, which allows any application running in the same non-administrative user context to intercept them in cleartext within process memory. By using this technique, a local attacker is able to obtain administrative credentials in order to elevate privileges. This vulnerability can be exploited by injecting code into Teamviewer.exe which intercepts calls to GetWindowTextW and logs the processed credentials.

Se detectó un problema en TeamViewer versiones 14.2.2558. La actualización del producto como un usuario no administrativo requiere ingresar credenciales administrativas en la GUI. Posteriormente, estas credenciales se procesan en el archivo Teamviewer.exe, lo que permite que cualquier aplicación que sea ejecutada en el mismo contexto de usuario no administrativo las intercepte en texto sin cifrar dentro de la memoria del proceso. Mediante el uso de esta técnica, un atacante local puede obtener credenciales administrativas para elevar los privilegios. Esta vulnerabilidad puede ser explotada inyectando código en el archivo Teamviewer.exe que intercepta las llamadas a GetWindowTextW y registra las credenciales procesadas.
