CVE-2022-2969
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 · uneditedDelta Industrial Automation DIALink versions prior to v1.5.0.0 Beta 4 uses an external input to construct a pathname intended to identify a file or directory located underneath a restricted parent directory. However, the software does not properly neutralize special elements within the pathname, which can cause the pathname to resolve to a location outside of the restricted directory.
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 confidenceDelta Industrial Automation DIALink versions before v1.5.0.0 Beta 4 contains a path traversal vulnerability where external input is used to construct file paths without proper sanitization of special elements like '../', allowing attackers to access files outside the restricted directory.

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.
-
Identify DIALink installation and versionLocate the DIALink application on the system and determine its installed version number (check application properties, About dialog, installed programs listing, or version file within the installation directory)Affected if The installed version is any release before v1.5.0.0 Beta 4, or is exactly version 1.5.0.0 (the vulnerable versions)
-
Confirm the application uses external input for file pathsExamine DIALink configuration, logs, or documentation to determine if the application accepts external input (user-provided paths, network requests, configuration parameters) to construct file paths for operationsAffected if The application processes external input to build file paths without documented sanitization of path traversal sequences like '../'
-
Check for path traversal protectionReview application security settings, logs, or available documentation for any path validation mechanisms that prevent directory traversalAffected if No path traversal protection (such as validation against '../' sequences or directory boundary checks) is configured or present
The environment is affected if DIALink version is below v1.5.0.0 Beta 4 (or equals 1.5.0.0) AND the application processes external input to construct file paths without proper path traversal validation.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scoped1.5.0.0
Upgrade DIALink to v1.5.0.0 Beta 4 or later. Implement proper path validation ensuring the constructed path remains within the intended directory boundaries, rejecting any input containing traversal sequences.
v1.5.0.0 Beta 4
- Obtain Delta Industrial Automation DIALink version 1.5.0.0 Beta 4 or later from the official vendor source
- Back up existing DIALink configurations and data before upgrading
- Uninstall the current affected version (versions < 1.5.0.0 or = 1.5.0.0)
- Install version 1.5.0.0 Beta 4 or later
- Verify the installation was successful and confirm the path traversal vulnerability is resolved
