Security readout for executives and security teams
Plain-English summary
Dynojet Power Core 2.3.0 Build 303 installs a Windows service with an unsafe service path. A person who already has local authenticated access could abuse this to run code with Local System privileges. This is not described as a remote internet attack, but it can turn a low-privilege workstation compromise into full system control.
Executive priority
Treat as high priority where Dynojet Power Core is installed on shared or user-accessible systems. The issue supports privilege escalation after initial local access, which can worsen endpoint compromise. Prioritize inventory first because affected deployments are likely specialized.
Technical view
CVE-2021-47773 is a CWE-428 unquoted service path issue in Dynojet Power Core’s DJ.UpdateService. The CVSS 4.0 score is 8.5. The attack vector is local, requires low privileges, needs no user interaction, and can impact confidentiality, integrity, and availability of the vulnerable host.
Likely exposure
Exposure is limited to Windows systems running Dynojet Power Core 2.3.0 Build 303 with the vulnerable DJ.UpdateService installed. Risk is highest on shared workstations, lab systems, or endpoints where non-admin users can log in locally.
Exploitation context
The source bundle references an ExploitDB entry, so public exploit information exists. The CVE is not listed as KEV in the provided data, and no cited source confirms active exploitation in the wild.
Researcher notes
Public details identify Dynojet Power Core 2.3.0 Build 303 and DJ.UpdateService. Sources do not name a vendor advisory, fixed version, or patch. Avoid assuming broader product impact without confirming installed version and service configuration.
Mitigation direction
- Identify hosts running Dynojet Power Core 2.3.0 Build 303.
- Check Dynojet guidance for an updated installer, patch, or service configuration fix.
- Restrict local interactive access to affected systems where practical.
- Remove or disable the software if it is not operationally required.
- Review service path configuration and directory permissions with endpoint hardening standards.
Validation and detection
- Inventory installed Dynojet Power Core versions and build numbers.
- Confirm whether DJ.UpdateService exists on each host.
- Review the service binary path for unquoted paths containing spaces.
- Check whether standard users can write to directories in the service path.
- Document affected hosts and track remediation status.
