Security readout for executives and security teams
Plain-English summary
CVE-2020-37074 is a critical buffer overflow in LizardSystems Remote Desktop Audit 2.3.0.157. A crafted computer-list import file can cause code execution during the Add Computers Wizard import process. This matters most where administrators use this tool on systems with privileged access to remote desktop inventory data.
Executive priority
Prioritize discovery and containment if this tool is used by IT administrators. Public exploit information and potential code execution raise business risk, but current sources do not prove active exploitation or name a patch.
Technical view
The issue is reported as CWE-120 in Remote Desktop Audit 2.3.0.157. Sources describe an SEH-based buffer overflow triggered by importing a crafted file in the Add Computers Wizard, enabling arbitrary code execution. The supplied CVSS is 9.8 with network attack vector, but the description indicates file import is involved.
Likely exposure
Exposure appears limited to organizations running LizardSystems Remote Desktop Audit version 2.3.0.157, especially on administrator workstations. The sources do not identify other affected versions or CPEs.
Exploitation context
A public ExploitDB entry exists, so proof-of-concept exploit information is public. The source bundle does not show CISA KEV listing or confirmed active exploitation. The described trigger involves importing a malicious file, so operational exposure depends on how the tool is used.
Researcher notes
Evidence is sufficient for affected product, version, vulnerability class, and public exploit availability. Evidence is incomplete on fixed versions, vendor advisory status, active exploitation, and whether user interaction is required despite the supplied UI:N CVSS vector.
Mitigation direction
- Identify any installations of Remote Desktop Audit 2.3.0.157.
- Check LizardSystems guidance for fixed versions or vendor-recommended remediation.
- Avoid importing untrusted computer-list files into the Add Computers Wizard.
- Restrict tool use to hardened, least-privilege administrator workstations.
- Remove or isolate the software if no vendor fix is available.
Validation and detection
- Inventory endpoints for LizardSystems Remote Desktop Audit installations.
- Confirm installed version numbers, focusing on 2.3.0.157.
- Review logs and user reports for unexpected crashes during file import.
- Verify whether users import computer lists from external or untrusted sources.
- Track vendor and CVE references for updated remediation details.
