CVE-2025-61156
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIncorrect access control in the kernel driver of ThreatFire System Monitor v4.7.0.53 allows attackers to escalate privileges and execute arbitrary commands via an insecure IOCTL.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA kernel driver in ThreatFire System Monitor v4.7.0.53 contains an insecure IOCTL (Input/Output Control) handler that lacks proper access control validation. This allows a local unprivileged attacker to send specially crafted IOCTL requests to the driver, escalating to kernel-level privileges and executing arbitrary system commands with full administrative rights.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check if ThreatFire System Monitor is installedSearch for ThreatFire in installed programs via Control Panel > Programs and Features, or check common installation paths such as C:\Program Files\ThreatFire or C:\Program Files (x86)\ThreatFireAffected if ThreatFire System Monitor is present on the system
-
Verify the installed versionRight-click the main ThreatFire executable (typically tf.exe or similar) and select Properties > Details to view the version, or check the Windows Registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for ThreatFire entriesAffected if The installed version matches 4.7.0.53
-
Check for the vulnerable kernel driverNavigate to C:\Windows\System32\drivers and look for the ThreatFire kernel driver file (commonly tf*.sys or similar naming pattern), or run 'driverquery /v' in an elevated command prompt to list loaded driversAffected if A ThreatFire kernel driver (.sys file) is present and loaded in memory
-
Identify running ThreatFire processesOpen Task Manager or run 'tasklist /fi "imagename eq tf*"' in Command Prompt to list active ThreatFire processesAffected if ThreatFire processes are actively running on the system
The environment is affected if ThreatFire System Monitor version 4.7.0.53 is installed and its kernel driver is loaded, as this enables the vulnerable IOCTL handler to be exploited.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataRemove or disable the ThreatFire System Monitor kernel driver if the software is no longer actively maintained. If continued use is required, contact the vendor for an updated patched version, or implement application whitelisting and restrict driver loading to prevent exploitation.
