CVE-2025-64992 is a vulnerability identified in TeamViewer DEX (formerly 1E DEX), specifically affecting versions prior to 25. The flaw exists in the 1E-Nomad-PauseNomadJobQueue instruction, where improper input validation allows authenticated users possessing Actioner privileges to perform command injection. This vulnerability is categorized under CWE-20, which relates to improper input validation. An attacker exploiting this flaw can inject arbitrary commands that execute remotely with elevated privileges on devices connected to the TeamViewer DEX platform. The vulnerability requires the attacker to be authenticated with Actioner-level permissions and involves user interaction, which somewhat limits the attack surface. The CVSS v3.1 score of 6.8 reflects a medium severity, with high impact on confidentiality, integrity, and availability due to the potential for remote code execution. No public exploit code or active exploitation has been reported to date. The vulnerability highlights the risk of insufficient input sanitization in remote management tools, which can lead to privilege escalation and system compromise. The lack of an official patch at the time of reporting necessitates immediate mitigation through access control and monitoring.

For European organizations, this vulnerability poses a significant risk, particularly for enterprises relying on TeamViewer DEX for remote device management and IT operations. Successful exploitation could lead to unauthorized command execution, potentially compromising sensitive data, disrupting operations, or enabling lateral movement within networks. Critical sectors such as finance, healthcare, manufacturing, and government agencies that use TeamViewer DEX to manage distributed devices are especially vulnerable. The medium severity rating reflects the requirement for authenticated access and user interaction, but the elevated privileges needed mean that insider threats or compromised credentials could be leveraged effectively. The impact on confidentiality, integrity, and availability is high, as attackers could execute arbitrary commands, modify system configurations, or disrupt services. Given the widespread use of TeamViewer products in Europe, a successful attack could have broad operational and reputational consequences.

1. Immediately restrict Actioner privileges to only trusted and essential personnel to reduce the risk of exploitation. 2. Implement strict input validation and command filtering at the application layer where possible, even before official patches are released. 3. Monitor logs and audit trails for unusual command execution patterns or unauthorized access attempts within TeamViewer DEX. 4. Employ network segmentation to isolate devices managed via TeamViewer DEX, limiting the potential spread of an attack. 5. Enforce multi-factor authentication (MFA) for all users with Actioner privileges to reduce the risk of credential compromise. 6. Stay informed on vendor advisories and apply official patches or updates as soon as they become available. 7. Conduct regular security training for administrators to recognize and report suspicious activities related to remote management tools. 8. Consider deploying endpoint detection and response (EDR) solutions to detect anomalous command execution on managed devices.
