Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match

prevent

Directly mitigates the vulnerability by requiring timely patching of TeamViewer to version 15.62 or later as recommended in the vendor security bulletin.

RA-5 Vulnerability Monitoring and Scanning partial match

preventdetect

Enables identification of systems with vulnerable TeamViewer versions through scanning, facilitating targeted remediation of the argument injection flaw.

AC-6 Least Privilege partial match

prevent

Limits the impact of privilege escalation from argument injection by ensuring the TeamViewer service and user accounts operate with least privilege.

MITRE ATT&CK Enterprise TechniquesAI

Why these techniques?

Local argument injection into TeamViewer service directly enables exploitation for privilege escalation (T1068) from unprivileged local access to SYSTEM-level control.

NVD Description

Improper Neutralization of Argument Delimiters in the TeamViewer_service.exe component of TeamViewer Clients prior version 15.62 for Windows allows an attacker with local unprivileged access on a Windows system to elevate privileges via argument injection.

Deeper analysisAI

CVE-2025-0065 involves improper neutralization of argument delimiters (CWE-88) in the TeamViewer_service.exe component of TeamViewer Clients prior to version 15.62 for Windows. Published on January 28, 2025, the vulnerability enables argument injection, with a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its potential for significant impact on system confidentiality, integrity, and availability.

An attacker requires local unprivileged access on a targeted Windows system to exploit this flaw. With low attack complexity and no user interaction needed, they can inject malicious arguments into the service process, achieving privilege escalation from a low-privileged account to higher privileges, potentially granting full system control.

TeamViewer's security bulletin (TV-2025-1001) at https://www.teamviewer.com/en/resources/trust-center/security-bulletins/tv-2025-1001/ addresses the vulnerability, recommending an update to TeamViewer Client version 15.62 or later to mitigate the argument injection risk.
