Security readout for executives and security teams
Plain-English summary
Ivanti Endpoint Manager components through 2020.1.1 may load a missing Windows library from an unsafe search location. If an attacker can meet the required local conditions, vulnerable components may run attacker-controlled code with their privileges, potentially NT AUTHORITY\SYSTEM.
Executive priority
Treat this as high priority for environments using Ivanti Endpoint Manager because successful exploitation could elevate code execution to highly privileged Windows contexts. Urgency is lower if the product is absent or versions are confirmed remediated.
Technical view
CVE-2020-13771 is a DLL hijacking issue caused by Windows search-order reliance when ldiscn32.exe, IpmiRedirectionService.exe, LDAPWhoAmI.exe, and ldprofile.exe load a nonexistent library. The available record does not provide CVSS, CWE, patch details, or precise preconditions.
Likely exposure
Exposure is limited to Ivanti Endpoint Manager deployments through 2020.1.1 where the named components are present and DLL search-order preconditions can be satisfied.
Exploitation context
The source bundle does not show CISA KEV listing or active exploitation evidence. Public disclosure exists via the referenced advisory. Practical risk depends on attacker ability to influence DLL search locations and the privileges of the affected component.
Researcher notes
Evidence is incomplete in the provided bundle: no CVSS, CWE, vendor fix version, or exact prerequisite path is supplied. Validate version exposure first, then assess DLL search-path writeability and component privilege context.
Mitigation direction
- Inventory Ivanti Endpoint Manager versions and affected components.
- Check Ivanti guidance for fixed versions or supported remediation.
- Restrict write access to application and service search paths.
- Monitor affected hosts for unexpected library load activity.
- Prioritize remediation where vulnerable components run as SYSTEM.
Validation and detection
- Confirm whether Ivanti Endpoint Manager is installed through version 2020.1.1.
- Check for ldiscn32.exe, IpmiRedirectionService.exe, LDAPWhoAmI.exe, and ldprofile.exe.
- Review service accounts and privileges for affected components.
- Audit writable directories in relevant application search paths.
- Correlate endpoint telemetry for suspicious DLL loads near these processes.
