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 · unedited
Comodo Internet Security Pro Directory Traversal Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of Comodo Internet Security Pro. 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 update mechanism. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM. Was ZDI-CAN-19055.

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 confidence

A directory traversal vulnerability in the update mechanism of Comodo Internet Security Pro allows local attackers to manipulate user-supplied file paths that are not properly validated, enabling privilege escalation from a low-privileged user context to SYSTEM level and arbitrary code execution.

MitigationApply vendor-supplied patch for Comodo Internet Security Pro when available; until then, restrict user access to the update mechanism and monitor for suspicious file operations.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Verify Comodo Internet Security Pro is installed
    Check for the product in Add/Remove Programs, or look for installation directory (typically C:\Program Files\Comodo\ or C:\Program Files (x86)\Comodo\), or query registry key HKLM\SOFTWARE\Comodo\ or HKLM\SOFTWARE\WOW6432Node\Comodo
    Affected if Comodo Internet Security Pro is found on the system
  2. Check the installed version number
    Open the Comodo UI and navigate to About/Support, or check the registry value at HKLM\SOFTWARE\Comodo\Version or look for version info in the main executable file properties
    Affected if The installed version is exactly 12.2.4.8032
  3. Verify the update mechanism is present
    Look for update-related executables (cis.exe, cmdupd.exe, or similar in the Comodo installation folder) and check if the Comodo update service is registered (run services.msc and look for Comodo Update Service)
    Affected if The Comodo update service or update executables exist on the system
  4. Check user permissions on update mechanism
    Right-click the Comodo installation folder, go to Properties > Security, and verify if standard users have modify or write access to update-related folders and files
    Affected if Low-privileged users have write or modify permissions to update mechanism files or directories
  5. Inspect update log files for traversal attempts
    Check the Comodo installation logs folder (often in %ProgramData%\Comodo\ or within the installation directory) for recent update logs containing unusual path patterns like ..\ or ..\\
    Affected if Update logs show directory traversal patterns or unusual file path operations

The system is affected if Comodo Internet Security Pro version 12.2.4.8032 is installed and the update mechanism is accessible to low-privileged users, enabling potential privilege escalation.
