CVE-2023-0623
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 · uneditedCscape Envision RV version 4.60 is vulnerable to an out-of-bounds write vulnerability when parsing project (i.e. HMI) files. The product lacks proper validation of user-supplied data, which could result in writes past the end of allocated data structures. An attacker could leverage these vulnerabilities to execute arbitrary code in the context of the current process.
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 confidenceCscape Envision RV version 4.60 contains an out-of-bounds write vulnerability during HMI project file parsing. The application fails to properly validate user-supplied data length or bounds before writing to memory structures, allowing a malformed project file to trigger writes beyond allocated buffer boundaries. Successful exploitation enables arbitrary code execution in the context of the current process.

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 Cscape Envision RV installationCheck your system for the presence of Cscape Envision RV software - look for the application in installed programs or search for executable files related to Cscape Envision RVAffected if The software is installed on the system
-
Verify installed version numberDetermine the exact version of Cscape Envision RV installed - check the application's about dialog, installed programs details, or version property of the executableAffected if The installed version is exactly 4.60
-
Confirm .csp file handling capabilityDetermine if the Cscape Envision RV application is configured to open or parse .csp project files - check file associations or recent file activityAffected if The application can process .csp project files and has been used to open such files
You are affected if Cscape Envision RV version 4.60 is installed and the application is capable of opening or parsing .csp project files, as the vulnerability is triggered during malformed project file processing.
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.
From vendor dataImplement robust input validation and bounds checking on all user-supplied data during file parsing operations; validate file structure, sizes, and offsets before processing. Avoid opening untrusted .csp project files until a vendor patch is applied.
