CVE-2018-7796
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 · uneditedA Buffer Error vulnerability exists in PowerSuite 2, all released versions (VW3A8104 & Patches), which could cause an overflow in the memcpy function, leading to corruption of data and program instability.
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 buffer overflow vulnerability exists in PowerSuite 2 (VW3A8104 and all patch versions) where improper bounds checking before a memcpy call allows data to exceed allocated buffer boundaries, leading to memory corruption and potential program instability.

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.
-
Confirm PowerSuite 2 installationLocate the PowerSuite 2 application on the system. Check for the executable VW3A8104 or the PowerSuite 2 program folder in typical installation directories (e.g., C:\Program Files\Schneider Electric\PowerSuite 2 or C:\Schneider Electric\PowerSuite 2).Affected if PowerSuite 2 (VW3A8104) is found installed on the system.
-
Identify installed versionRight-click the PowerSuite 2 executable, select Properties, then view the Details tab for version information. Alternatively, open PowerSuite 2 and navigate to Help > About to display the exact version and build number.Affected if The installed version cannot be determined or is any version of PowerSuite 2.
-
Verify version against affected rangeCompare the identified version number to the affected product designation (VW3A8104 and all patch versions). Schneider Electric lists this as all versions of PowerSuite 2.Affected if The version is VW3A8104 or any subsequent patch version of PowerSuite 2.
-
Confirm vulnerable functionality is in useThis buffer overflow occurs during memcpy operations within the application. The vulnerability is inherent to the software when processing data. No specific feature toggle is required; the flaw exists in the core application code when handling data that triggers the unbounded memcpy.Affected if PowerSuite 2 is installed and operational, meaning the vulnerable code path is present.
If PowerSuite 2 (VW3A8104) is installed at any version, the environment is affected by this vulnerability.

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 dataApply any available vendor patches for PowerSuite 2; if no patch exists, implement input validation and size checking before memcpy operations to ensure source data does not exceed destination buffer capacity.
