Security readout for executives and security teams
Plain-English summary
CVE-2021-47828 affects BOOTP Turbo 2.0.0.1253 on Windows. A misconfigured service path can let a local low-privileged attacker get code run as LocalSystem after startup or reboot. This is mainly a privilege-escalation risk on systems where the product is installed.
Executive priority
Treat this as a high-priority internal hardening issue, especially on shared Windows servers or systems with many local users. It is not described as remotely exploitable, but successful abuse could give full system-level control of an affected host.
Technical view
The issue is CWE-428, an unquoted Windows service path in BOOTP Turbo’s bootpt.exe service configuration. The CVSS 4.0 score is 8.5 with local attack vector, low complexity, low privileges required, and high impact to confidentiality, integrity, and availability of the vulnerable system.
Likely exposure
Exposure is limited to Windows hosts running Weird-Solutions BOOTP Turbo version 2.0.0.1253 with the affected service installed. Organizations should prioritize systems where local users, service accounts, or attackers could write to relevant path locations.
Exploitation context
The source bundle lists an ExploitDB entry, indicating public exploit information exists. The CVE is not listed as KEV in the provided data, so active exploitation is not established here. Exploitation requires local access and is triggered through service startup or reboot conditions.
Researcher notes
Evidence supports a local privilege escalation in BOOTP Turbo 2.0.0.1253 via unquoted service path. Public exploit reference exists, but active exploitation is not evidenced by KEV or the provided sources. Patch status is unclear from the bundle; rely on vendor guidance for definitive remediation.
Mitigation direction
- Inventory BOOTP Turbo installations and identify version 2.0.0.1253.
- Check Weird-Solutions guidance for an update, configuration fix, or supported remediation.
- Remove or disable BOOTP Turbo where it is not operationally required.
- Restrict local write access on affected hosts to trusted administrators only.
- Increase monitoring for unexpected service changes or suspicious startup persistence.
Validation and detection
- Confirm whether BOOTP Turbo 2.0.0.1253 is installed on Windows hosts.
- Review the BOOTP Turbo service configuration for an unquoted executable path.
- Check whether non-administrative users can write to relevant parent directories.
- Verify service hardening after applying vendor guidance or configuration changes.
- Document affected hosts, remediation status, and remaining operational exceptions.
