Arbitrary File Deletion via IOCTL in IObit Malware Fighter 6.2 IMFForceDelete.sys

IdentifiersCVE-2019-6494CWE-732

A vulnerability in the IMFForceDelete.sys driver of IObit Malware Fighter 6.2 allows a low privileged user to send IOCTL 0x8016E000 with a user-defined string specifying a file path. The driver will then delete the specified file, bypassing standard access controls and permissions. This allows arbitrary file deletion on the system by any local user.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

A local attacker can delete any file on the system, including critical system files or files belonging to other users, leading to potential denial of service, privilege escalation, or system instability.

Mitigation

If you can’t patch tonight, do this now.

Restrict access to the vulnerable driver to trusted users only. Monitor for and block suspicious IOCTL requests to IMFForceDelete.sys. Remove or disable the driver if not required until a patched version is available.

Remediation

Patch, then assume compromise.

Update to a version of IObit Malware Fighter where IMFForceDelete.sys properly validates user privileges and restricts file deletion operations to authorized users only. Ensure that the driver does not allow arbitrary file paths from unprivileged users.
