CVE-2016-4523
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 · uneditedThe WAP interface in Trihedral VTScada (formerly VTS) 8.x through 11.x before 11.2.02 allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via unspecified vectors.
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 confidenceThe WAP interface in Trihedral VTScada versions 8.x through 11.x before 11.2.02 contains an out-of-bounds read vulnerability. Remote attackers can exploit this memory safety issue via unspecified vectors to cause a denial of service through application crash.

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.
-
Verify Trihedral VTScada installationLocate VTScada installation on the system by checking common installation directories or the program listing in the operating system's installed programs listAffected if VTScada is present on the system
-
Identify installed VTScada versionUse the system's installed programs list, or check VTScada-specific version information through its application properties or about dialog if accessibleAffected if The version returned is greater than or equal to 8.0.05 and less than 11.2.02
-
Determine if WAP interface is configuredReview VTScada configuration files or settings to check whether the WAP interface component has been enabled or set upAffected if The WAP interface is enabled or configured on the system
-
Assess network exposure of WAP interfaceCheck network configuration or firewall rules to determine if the WAP interface port is accessible from untrusted networksAffected if The WAP interface is reachable from external or untrusted network segments
The system is affected if Trihedral VTScada is installed with a version between 8.0.05 and 11.2.01 inclusive and the WAP interface is enabled or accessible.
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 · scoped11.2.02
Upgrade VTScada to version 11.2.02 or later. If immediate patching is not feasible, restrict network access to the WAP interface using firewalls or network segmentation to limit exposure to untrusted networks.
VTScada 11.2.02 or later
- Download VTScada version 11.2.02 or later from the official Trihedral/VTScada vendor website
- Review the upgrade documentation specific to your current VTScada version
- Backup the existing VTScada project files and database before initiating the upgrade
- Stop all VTScada services and related processes on the server
- Install VTScada 11.2.02 or later following the vendor's installation procedures
- Restart VTScada services after installation completes
- Verify that the WAP interface is functioning properly and the application is stable
