Privilege Escalation via Argument Injection in TeamViewer Clients

CVE-2025-0065

What is CVE-2025-0065?

CVE-2025-0065 is a privilege escalation vulnerability identified in TeamViewer Clients, specifically affecting versions prior to 15.62 on Windows operating systems. TeamViewer is a widely-used remote access and support software that facilitates online collaboration and remote support for users and organizations. The vulnerability arises from improper handling of argument delimiters within the TeamViewer service component, allowing an attacker who has already gained local, unprivileged access to elevate their privileges. This can negatively impact an organization by potentially granting unauthorized users heightened access, compromising sensitive data and system integrity.

Technical Details

The core issue of CVE-2025-0065 lies in the improper neutralization of argument delimiters within the TeamViewer_service.exe component. This flaw permits an attacker to craft input that can manipulate the execution environment of the TeamViewer service, leading to a situation where they can execute commands or access resources that are typically restricted. The vulnerability is specifically present in versions of TeamViewer prior to 15.62 for the Windows platform, necessitating immediate action to shield affected systems from exploitation.

Potential Impact of CVE-2025-0065

1. Unauthorized Access to Sensitive Data: If exploited, an attacker could potentially gain access to confidential information, such as organizational data, customer records, and sensitive files, leading to data breaches and possible regulatory non-compliance.

2. System Compromise: The ability to elevate privileges could allow an attacker full control over the affected machine, raising significant risks for the entire network. This may enable further attacks within the organization, including lateral movement to other systems.

3. Operational Disruption: Successful exploitation may cause disruptions in TeamViewer services, affecting remote support operations and collaborative efforts. This could lead to significant downtime and hinder business continuity, ultimately impacting productivity.
