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
idreamsoft iCMS 7.0.11 allows admincp.php?app=config Directory Traversal, resulting in execution of arbitrary PHP code from a ZIP file.

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

idreamsoft iCMS 7.0.11 contains a directory traversal vulnerability in admincp.php?app=config that allows authenticated administrators to traverse filesystem directories and write/extract arbitrary files, including PHP code from ZIP archives, leading to remote code execution.

MitigationImplement strict input validation on file path parameters to prevent directory traversal sequences (..). Additionally, validate and sanitize ZIP extraction paths to ensure extracted files remain within intended directories. Consider restricting admin access and applying principle of least privilege.

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. Confirm iCMS version installed
    Locate and read the version file or header in the iCMS installation directory. Common paths include a version.php, about.php, or check the footer/meta of admin pages. Compare the version number to 7.0.11.
    Affected if The installed version is exactly 7.0.11
  2. Verify admincp.php exists
    Check for the presence of admincp.php in the web root or admin directory of the iCMS installation.
    Affected if admincp.php exists and is accessible via the web server
  3. Confirm app=config parameter handling exists
    Inspect the source code of admincp.php to verify it processes an 'app' parameter and specifically contains logic for 'config' application handling.
    Affected if The code contains an app parameter handler that routes to config functionality
  4. Check for ZIP extraction functionality
    Examine the config handling code for functions that process file uploads, ZIP archives, or file extraction operations that accept user-controlled paths.
    Affected if The code contains ZIP extraction or file write operations that use path parameters controllable by the user
  5. Verify administrator authentication is required
    Review the access control logic in admincp.php to confirm that administrator authentication is enforced before allowing the vulnerable file operation.
    Affected if The vulnerable endpoint requires only authenticated administrator access (not publicly exposed)

Your environment is affected if you are running iCMS version 7.0.11 with admincp.php accessible to authenticated administrators and the config app contains the vulnerable ZIP extraction/file write logic.
