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 · uneditedUnitronics Unistream Unilogic – Versions prior to 1.35.227 - CWE-23: Relative Path Traversal
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 confidenceA relative path traversal vulnerability (CWE-23) in Unitronics Unistream Unilogic versions prior to 1.35.227 allows attackers to access files outside the intended directory by manipulating path traversal sequences (e.g., ../). This high-severity (CVSS 8.8) flaw could enable unauthorized read access to sensitive system files.

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 Unilogic installation versionLocate the installed Unilogic software on the system and determine its version number. This can typically be found in the Windows Add/Remove Programs list, the program's Help > About menu, or the executable file properties.Affected if The installed version is prior to 1.35.227 (for example, 1.35.200, 1.34.x, or earlier)
-
Verify version comparison against affected rangeCompare the identified version against the known vulnerable range: any version less than 1.35.227 is affected.Affected if The version number is below 1.35.227 (the first fixed release)
-
Confirm file access functionality is in useDetermine if the Unilogic application or any project deployed from it handles file path parameters, as the path traversal vulnerability affects file access operations.Affected if The system processes user-supplied or derived file paths without strict validation, which would trigger the vulnerable code path
You are affected if the installed Unilogic version is any release prior to 1.35.227 and the application handles file path operations.
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 · scoped1.35.227
Upgrade Unilogic to version 1.35.227 or later. If immediate patching is not feasible, implement strict input validation on file path parameters and restrict file system access permissions to limit exposure.
Unilogic version 1.35.227
- 1. Obtain Unilogic version 1.35.227 or later from the official Unitronics website or authorized distribution channels
- 2. Back up all existing Unilogic project files and configurations before upgrading
- 3. Uninstall the current version of Unilogic if necessary
- 4. Install Unilogic version 1.35.227 or newer
- 5. Verify the installation by checking the software version in the About or Help section
- 6. Reopen and validate existing projects function correctly after the upgrade
