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
A CWE-22 Improper Limitation of a Pathname to a Restricted Directory ('Path Transversal') vulnerability exists in SCADAPack 7x Remote Connect (V3.6.3.574 and prior) which allows an attacker to place content in any unprotected folder on the target system using a crafted .RCZ 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 · high confidence

This is a path traversal vulnerability in SCADAPack 7x Remote Connect (versions prior to V3.6.3.575). The vulnerability allows attackers to craft malicious .RCZ files that, when processed by the application, can write content to arbitrary directories outside the intended restricted folder, bypassing directory limitation controls.

MitigationUpdate SCADAPack 7x Remote Connect to version V3.6.3.575 or later. If patching is not immediately possible, restrict or disable the processing of .RCZ files from untrusted sources and monitor for unauthorized file writes to system directories.

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. Determine installed version of SCADAPack 7x Remote Connect
    Open the application and navigate to Help > About, or check the installed programs list in Windows Control Panel > Programs and Features, to locate the exact version number
    Affected if The version listed is 3.6.3.574 or lower (any version prior to V3.6.3.575)
  2. Confirm .RCZ file processing is available
    Check if the application has the capability to import or process .RCZ configuration files - look for import/load options in the file menu or settings
    Affected if The application can import or load .RCZ files and the version is vulnerable as determined above
  3. Inspect recent file system activity for unauthorized writes
    Use Windows Event Viewer or file system monitoring tools to review recent write operations, particularly checking for files written outside the expected project/restricted directories
    Affected if Any .RCZ-related file write operations have created files in directories outside the intended restricted folder

A user is affected if they have SCADAPack 7x Remote Connect version 3.6.3.574 or earlier installed and the application processes .RCZ files from any source
