CVE-2016-20059 Iobit CVE debrief

Who should care

System administrators and security professionals responsible for managing and securing IObit Malware Fighter installations, particularly version 4.3.1, should be aware of this vulnerability. This vulnerability can be exploited by local attackers, making it a significant concern for organizations using this software.

Technical summary

The vulnerability exists due to the unquoted service path in IMFservice and LiveUpdateSvc services of IObit Malware Fighter 4.3.1. Local attackers can exploit this by placing a malicious executable in the service path, which can be executed with LocalSystem privileges when the service restarts or the system reboots. This issue is particularly concerning for system administrators and security professionals, as it can lead to significant privilege escalation and potential system compromise. Affected product deployments should be identified, and owners assigned for follow-up. Official advisories and CVE records should be reviewed to validate affected scope, severity, and vendor guidance. Compensating controls, such as restricting write access to service paths and monitoring for suspicious activity, should be implemented.

Defensive priority

High priority should be given to patching or mitigating this vulnerability, as it can lead to significant privilege escalation and potential system compromise.

Recommended defensive actions

• Apply the latest patch or update from IObit to address the unquoted service path vulnerability.
• Implement compensating controls, such as restricting write access to service paths and monitoring for suspicious activity.
