Security readout for executives and security teams
Plain-English summary
Remote Desktop Manager could leave MySQL-backed database sessions active after a user was deleted. A removed user might still reach data they should no longer access. The main business risk is confidentiality loss where user deletion is relied on to immediately revoke access.
Executive priority
Treat as a high-priority confidentiality issue for affected RDM environments. It undermines account deprovisioning, which can create audit, insider-risk, and data-exposure concerns.
Technical view
Devolutions Remote Desktop Manager 2022.3.7 and earlier has an access-control weakness involving MySQL data sources. Database connections tied to deleted users could remain active, allowing unauthorized data access. The CVE maps to CWE-284 and carries CVSS 3.1 score 7.5 for high confidentiality impact.
Likely exposure
Organizations using Remote Desktop Manager 2022.3.7 or earlier with MySQL data sources and deleted user accounts are the relevant exposure group.
Exploitation context
The source bundle does not show CISA KEV listing or any cited evidence of active exploitation. Exploitability details are limited to the CVE description and CVSS vector.
Researcher notes
Evidence is narrow but clear: affected versions are 2022.3.7 and prior, with MySQL data sources specifically named. The bundle does not provide exploit telemetry, proof-of-concept details, or explicit patch-version text beyond the affected range.
Mitigation direction
- Identify Remote Desktop Manager instances at version 2022.3.7 or earlier.
- Prioritize moving affected deployments off vulnerable versions per Devolutions guidance.
- Review MySQL data-source access after user deletion events.
- Terminate lingering database sessions for removed users where operationally safe.
- Check Devolutions advisory DEVO-2022-0008 for current remediation instructions.
Validation and detection
- Inventory Remote Desktop Manager versions and MySQL data-source configurations.
- Confirm whether deleted users had active database sessions after removal.
- Review access logs for removed users after deletion timestamps.
- Verify account removal now terminates access to protected data.
- Document compensating controls if upgrade timing is delayed.

Improper Access Control
Improper Access Control represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
