Security readout for executives and security teams
Plain-English summary
CVE-2020-24089 is a local denial-of-service issue in the IOBit Malware Fighter 8.0.2 driver ImfHpRegFilter.sys. The available sources do not show remote attack, data theft, privilege escalation, active exploitation, or a confirmed vendor fix.
Executive priority
Treat this as a targeted availability risk, not a confirmed breach vector. Prioritize finding version 8.0.2 installations and checking vendor guidance, especially where endpoint stability matters or untrusted local users can access the machine.
Technical view
The CVE describes CWE-400 resource exhaustion in ImfHpRegFilter.sys, a driver associated with IOBit Malware Fighter 8.0.2. Local attackers can trigger denial of service. The bundle provides no CVSS vector, affected CPEs, crash scope, exploit prerequisites, or remediation details.
Likely exposure
Exposure appears limited to systems running IOBit Malware Fighter version 8.0.2 with ImfHpRegFilter.sys present. The CVE record lists affected vendor and product as n/a, so asset validation must rely on installed software and driver inventory.
Exploitation context
The source bundle supports local attacker denial of service only. It does not support active exploitation, remote exploitation, authentication bypass, code execution, or privilege escalation. KEV status is false, and the GitHub reference should not be treated as evidence of in-the-wild exploitation.
Researcher notes
Evidence is sparse. The CVE record gives a local DoS description and CWE-400, but no CVSS, CPE, root-cause detail, patch statement, or verified exploit conditions. Do not broaden affected versions beyond IOBit Malware Fighter 8.0.2 without additional vendor evidence.
Mitigation direction
- Identify endpoints running IOBit Malware Fighter 8.0.2.
- Check IOBit vendor guidance for fixed versions or workarounds.
- Prioritize remediation on shared, kiosk, or high-availability Windows systems.
- Restrict local interactive access on systems where the product remains installed.
- Monitor for crashes involving ImfHpRegFilter.sys.
Validation and detection
- Inventory installed IOBit Malware Fighter versions across endpoints.
- Check for ImfHpRegFilter.sys on suspected Windows systems.
- Review endpoint crash logs for this driver name.
- Confirm whether vendor documentation names a fixed release.
- Track whether NVD, CVE, or vendor metadata adds CVSS or affected CPEs.

Uncontrolled Resource Consumption
Uncontrolled Resource Consumption represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
