CVE-2024-7249
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 · uneditedComodo Firewall Link Following Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of Comodo Firewall. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the cmdagent executable. By creating a symbolic link, an attacker can abuse the application to delete a file. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM. Was ZDI-CAN-21794.
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 confidenceThis is a link following local privilege escalation vulnerability in Comodo Firewall's cmdagent.exe. An attacker with existing low-privileged code execution can create a symbolic link to manipulate the application into deleting an arbitrary file, which can be leveraged to escalate privileges to SYSTEM context and execute arbitrary code.

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.
-
Verify Comodo Firewall installationCheck for the presence of Comodo Firewall on the system by looking for the installation directory (typically C:\Program Files\COMODO\ or C:\Program Files (x86)\COMODO\) or by querying the Windows registry under HKLM\SOFTWARE\COMODO or HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for Comodo entriesAffected if Comodo Firewall is installed on the system
-
Check installed Comodo Firewall versionLocate the cmdagent.exe file (typically in C:\Program Files\COMODO\Comodo Firewall\ or C:\Program Files (x86)\COMODO\Comodo Firewall\) and right-click to view Properties, or query the registry uninstall key, or run 'wmic product where "name like '%Comodo%'" get version'Affected if The installed version is exactly 12.2.2.8012
-
Verify cmdagent.exe is present and executableConfirm cmdagent.exe exists in the Comodo Firewall installation directory and check if the process is running using Task Manager or 'tasklist | findstr cmdagent'Affected if cmdagent.exe exists and is running with elevated privileges
-
Inspect file deletion behavior through symlink manipulationAs a low-privileged user, create a test symbolic link using 'mklink testlink.txt targetfile.txt' in a directory where cmdagent has write access, then observe if cmdagent can be induced to follow the link and delete the target fileAffected if A low-privileged user can create symbolic links in directories used by cmdagent and the application follows those links to perform file operations
The system is affected if Comodo Firewall version 12.2.2.8012 is installed and cmdagent.exe is running with permissions that allow a low-privileged attacker to create symbolic links in its working directories.

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 dataApply the vendor-supplied patch or update Comodo Firewall to the latest version. As an interim control, restrict write access to directories where cmdagent operates and monitor for suspicious symbolic link creation.
