Description Preview
TeamViewer Remote versions 15.41 through 15.42.7 for Windows and macOS contain a vulnerability where an improper authorization check of local device settings allows unprivileged users to modify basic configuration settings even when those options were intentionally locked by administrators. This security flaw enables unauthorized users to make unwanted changes to the TeamViewer configuration, potentially undermining security controls and administrative policies set for the application.
Overview
This vulnerability (CVE-2023-0837) affects TeamViewer Remote versions 15.41 through 15.42.7 on both Windows and macOS platforms. The issue stems from insufficient authorization checks when validating user permissions to modify local device settings. When administrators lock certain configuration options to prevent changes, this protection mechanism can be bypassed by unprivileged users, allowing them to modify settings that should be restricted. This could lead to unauthorized configuration changes that may impact security posture, operational functionality, or compliance with organizational policies. The vulnerability specifically affects basic local device settings within the TeamViewer application.
Remediation
To address this vulnerability, organizations should:
- Update TeamViewer Remote to version 15.43 or later, which contains the fix for this vulnerability.
- Verify that all TeamViewer installations across the organization have been updated.
- Review any TeamViewer configurations that may have been altered during the vulnerable period.
- Consider implementing additional access controls or monitoring for TeamViewer usage if possible.
- Follow the principle of least privilege by restricting which users have access to TeamViewer.
- Monitor for any unusual activity or configuration changes in TeamViewer installations.
