CVE-2023-1864
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 · uneditedFANUC ROBOGUIDE-HandlingPRO Versions 9 Rev.ZD and prior is vulnerable to a path traversal, which could allow an attacker to remotely read files on the system running the affected software.
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 confidenceFANUC ROBOGUIDE-HandlingPRO Versions 9 Rev.ZD and prior contains a path traversal vulnerability that allows remote attackers to read arbitrary files on the system by manipulating file path inputs using ../ sequences. This could expose sensitive system files, configuration data, or credentials.

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 installed ROBOGUIDE-HandlingPRO versionCheck the application's version information through the installed software list, about dialog, or version file in the installation directory. Compare against 9 Rev.ZD as the fixed reference point.Affected if The installed version is 9 Rev.ZD or any prior version (e.g., 9 Rev.ZC, 9 Rev.Y, etc.)
-
Locate the web service or file handling interfaceIdentify if ROBOGUIDE-HandlingPRO exposes a web server, API, or file upload/download functionality that processes file path inputs. Check for running services on common ports or application configuration files.Affected if A web interface or file handling service is exposed and accepts file path parameters
-
Test for path traversal vulnerabilityIf a file path input field is accessible (such as file open, file browse, or export functions), attempt to manipulate the input by inserting ../ sequences to reference files outside the expected directory.Affected if The application accepts ../ sequences in file path parameters and returns contents of files outside the intended directory scope
-
Review application logs for traversal attemptsExamine application and web server logs for evidence of path traversal patterns (such as ../ or ..\) in request parameters or file access logs.Affected if Logs show successful traversal to system files using ../ patterns
You are affected if ROBOGUIDE-HandlingPRO version is 9 Rev.ZD or earlier AND the system has a web interface or file handling feature that processes user-supplied file paths without proper validation.

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 · scoped9_rev.zd
Apply vendor patch when available. Until then, implement strict input validation on all file path parameters using allowlist approaches and canonicalize paths to prevent traversal sequences.
Any version newer than 9 Rev.ZD (contact FANUC for specific fixed release)
- Contact FANUC technical support to obtain the latest patched version of ROBOGUIDE-HandlingPRO
- Request and confirm the specific version number that addresses the path traversal vulnerability (CVE-2023-1864)
- Before upgrading, backup all existing projects and configuration data
- Uninstall the current affected version (9 Rev.ZD or prior)
- Install the patched version provided by FANUC
- Verify the installation by confirming the software version number
- Test that normal operations function correctly after upgrade
