CVE-2026-0747: Remote Desktop Manager Info Disclosure

CVE-2026-0747 Overview

CVE-2026-0747 is an Information Exposure vulnerability affecting the TeamViewer entry dashboard component in Devolutions Remote Desktop Manager. The vulnerability exists in versions 2025.3.24.0 through 2025.3.28.0 on Windows platforms and allows sensitive password information to be exposed due to a defective masking feature. An external observer can view passwords displayed on screen through physical observation or during screen sharing sessions.

Critical Impact

Passwords stored in TeamViewer entries can be inadvertently exposed to unauthorized observers through the defective masking feature, potentially compromising credential security during screen sharing or physical proximity scenarios.

Affected Products

• Devolutions Remote Desktop Manager 2025.3.24.0 (Windows)
• Devolutions Remote Desktop Manager 2025.3.25.0 through 2025.3.27.0 (Windows)
• Devolutions Remote Desktop Manager 2025.3.28.0 (Windows)

Technical Details for CVE-2026-0747

Vulnerability Analysis

This vulnerability falls under CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor). The TeamViewer entry dashboard component in Devolutions Remote Desktop Manager contains a defective password masking feature that fails to properly obscure sensitive credential information when displayed on screen.

Password masking is a fundamental security control designed to prevent visual exposure of credentials. When this control fails, any password displayed in the TeamViewer entry dashboard becomes visible in plaintext rather than being obscured with asterisks or other masking characters. This creates an opportunity for credential theft through visual observation.

The attack requires local access, meaning an attacker must either have physical proximity to view the screen directly or be participating in a screen sharing session where the affected dashboard is visible. While this limits the attack surface compared to remote exploitation, the impact is significant in collaborative or open office environments where screen sharing is common.

Root Cause

The root cause of this vulnerability is a defective implementation of the password masking feature in the TeamViewer entry dashboard component. The masking mechanism fails to properly obscure password fields, resulting in credentials being displayed in a readable format instead of being hidden behind masking characters. This represents an implementation flaw in the user interface security controls.

Attack Vector

The attack vector is local (AV:L), requiring the attacker to have visual access to the victim's screen. Exploitation scenarios include:

1. Physical Observation: An attacker in physical proximity to the victim can observe the unmasked password displayed in the TeamViewer entry dashboard
2. Screen Sharing Sessions: During remote collaboration, video conferences, or screen sharing presentations, participants can capture or view exposed credentials
3. Screen Recording: If the user records their screen while the vulnerable dashboard is displayed, the password becomes permanently captured in the recording

The vulnerability requires user interaction (UI:R), specifically that the victim must navigate to the TeamViewer entry dashboard where the password is displayed. No privileges are required on the victim's system for the attacker to observe the exposed information.

Detection Methods for CVE-2026-0747

Indicators of Compromise

• Monitor for installations of Devolutions Remote Desktop Manager versions 2025.3.24.0 through 2025.3.28.0 in your environment
• Review screen sharing and video conferencing logs for sessions where Remote Desktop Manager was visible
• Check for any reported incidents involving credential exposure or unauthorized access to systems managed via TeamViewer entries
• Audit password access and changes for accounts stored in affected Remote Desktop Manager installations

Detection Strategies

• Implement software inventory scanning to identify systems running vulnerable versions of Devolutions Remote Desktop Manager
• Configure endpoint detection rules to alert on the presence of Remote Desktop Manager executables with vulnerable version signatures
• Deploy data loss prevention (DLP) tools to monitor screen sharing applications for potential credential exposure patterns
• Establish user awareness programs to encourage reporting of suspected credential exposure incidents

Monitoring Recommendations

• Track Remote Desktop Manager version deployments across the enterprise using software asset management tools
• Monitor for TeamViewer credential-related authentication anomalies that may indicate compromised credentials
• Implement logging for Remote Desktop Manager application access and dashboard navigation events where possible
• Review screen recording policies and stored recordings for potential credential exposure

How to Mitigate CVE-2026-0747

Immediate Actions Required

• Update Devolutions Remote Desktop Manager to a version newer than 2025.3.28.0 that contains the fix for the defective masking feature
• Rotate any passwords that may have been exposed through the TeamViewer entry dashboard during screen sharing sessions or physical observation
• Notify users of the vulnerability and advise against displaying the TeamViewer entry dashboard during screen sharing until patched
• Review access logs for any suspicious activity on accounts whose credentials were stored in the affected component

Patch Information

Devolutions has released a security advisory addressing this vulnerability. Users should consult the Devolutions Security Advisory DEVO-2026-0002 for specific patch information and upgrade instructions. Updating to a version beyond 2025.3.28.0 will resolve the password masking defect.

Workarounds

• Avoid accessing the TeamViewer entry dashboard when screen sharing or in environments where unauthorized individuals may observe the screen
• Use Remote Desktop Manager's alternative credential viewing methods if available that are not affected by the masking defect
• Temporarily remove or relocate sensitive credentials from TeamViewer entries until the patch can be applied
• Implement privacy screens on workstations in shared office environments to limit physical observation attacks
