CVE-2018-7511
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 · uneditedIn Eaton ELCSoft versions 2.04.02 and prior, there are multiple cases where specially crafted files could cause a buffer overflow which, in turn, may allow remote execution of arbitrary code.
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 confidenceIn Eaton ELCSoft versions 2.04.02 and prior, multiple buffer overflow vulnerabilities exist in file parsing functionality. Specially crafted files can trigger buffer overflow conditions, potentially allowing remote execution of arbitrary code.

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 ELCSoft installationLocate the Eaton ELCSoft application on the system. Check for the presence of ELCSoft program files, typically found in the installation directory (commonly C:\Program Files\Eaton\ELCSoft or similar path).Affected if ELCSoft software is installed on the system
-
Identify installed version numberAccess the application properties or about dialog within ELCSoft, or check the version information of the executable file (right-click the ELCSoft executable, select Properties, view the Details tab for Version).Affected if The exact version number cannot be determined or the version displayed is unclear
-
Compare version to affected rangeCompare the identified version against the affected range: any version prior to 2.04.02 is vulnerable. Versions 2.04.02 and prior are affected; versions greater than 2.04.02 are not.Affected if The installed version is lower than 2.04.02 (for example, 2.04.01, 2.04.00, 1.x.x, etc.)
-
Verify file parsing exposureSince this vulnerability is triggered through malicious file parsing, determine whether the system processes files through ELCSoft. Check if users can submit or import files into the application for processing.Affected if ELCSoft processes or imports external files and the version is below 2.04.02
The system is affected if Eaton ELCSoft is installed with a version number lower than 2.04.02 and the application processes external files, as this enables the buffer overflow vulnerability in file parsing to be exploited.

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 data2.04.02
Update ELCSoft to a patched version beyond 2.04.02 when available. Restrict file handling permissions and validate input files before processing. Network segmentation can limit exposure since CVSS indicates the attack vector may involve processing of malicious files.
