CVE-2025-64993
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA command injection vulnerability was discovered in TeamViewer DEX (former 1E DEX), specifically within the 1E-ConfigMgrConsoleExtensions instructions. Improper input validation, allowing authenticated attackers with Actioner privileges to inject arbitrary commands. Exploitation enables remote execution of elevated commands on devices connected to the platform.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA command injection vulnerability exists in TeamViewer DEX's 1E-ConfigMgrConsoleExtensions due to improper input validation. Authenticated users with Actioner privileges can inject arbitrary commands, leading to elevated remote code execution on connected devices.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify TeamViewer DEX versionLocate TeamViewer Digital Employee Experience installation and check the installed version number (usually found in Add/Remove Programs, the application itself, or its installer).Affected if The installed version is below 29.0 (any version < 29.0).
-
Confirm 1E-ConfigMgrConsoleExtensions componentCheck if the 1E-ConfigMgrConsoleExtensions module is installed. This may appear in the TeamViewer DEX interface, installed programs list, or configuration files under the TeamViewer installation directory.Affected if The 1E-ConfigMgrConsoleExtensions component is present and installed.
-
Identify Actioner role assignmentsReview user role assignments within the TeamViewer DEX administrative console. Look for users or groups assigned the 'Actioner' privilege level in the role-based access control settings.Affected if Any user account is assigned the Actioner role, particularly if that account is accessible to more than one trusted administrator.
A user is affected if their TeamViewer DEX installation is version below 29.0, the 1E-ConfigMgrConsoleExtensions component is present, and users with Actioner privileges exist in the system.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped29.0
Implement strict input validation and sanitization for all user-supplied parameters in the 1E-ConfigMgrConsoleExtensions, preferably using allowlist validation and avoiding dynamic command construction.
TeamViewer DEX 29.0
- Back up all current TeamViewer DEX configuration data and settings before proceeding with the upgrade
- Download TeamViewer Digital Employee Experience version 29.0 or later from the official TeamViewer download portal
- Review TeamViewer DEX 29.0 release notes for any specific upgrade prerequisites or migration requirements
- Execute the upgrade process following the official TeamViewer DEX installation/upgrade documentation
- After upgrade completion, verify that the 1E-ConfigMgrConsoleExtensions component is functioning correctly
- Confirm that the improper input validation vulnerability is remediated by testing command injection prevention in the affected component
- Validate that users with Actioner privileges can no longer inject arbitrary commands through the 1E-ConfigMgrConsoleExtensions interface
