CVE-2016-2277
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 · uneditedIAB.exe in Rockwell Automation Integrated Architecture Builder (IAB) before 9.6.0.8 and 9.7.x before 9.7.0.2 allows remote attackers to execute arbitrary code via a crafted project file.
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 confidenceIAB.exe in Rockwell Automation Integrated Architecture Builder has a file parsing vulnerability that allows remote attackers to execute arbitrary code via a crafted project file. The application does not properly validate project file input before processing, enabling code execution.

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.
-
Locate IAB installation and executableSearch for IAB.exe in typical installation paths such as C:\Program Files\Rockwell Automation\Integrated Architecture Builder\ or C:\Program Files (x86)\Rockwell Automation\Integrated Architecture Builder\ and note the file location.Affected if IAB.exe exists in these directories and the application is used for processing project files.
-
Determine installed IAB versionRight-click on IAB.exe, select Properties, then view the Details tab to see the Product Version. Alternatively, open IAB and check Help > About Integrated Architecture Builder.Affected if The version is 9.6.0.7 or earlier, or exactly 9.7.0.0 or 9.7.0.1.
-
Verify project file import capability is accessibleLaunch IAB and navigate to File menu to confirm the Open or Import project file options are available. In vulnerable versions, the application processes project files without proper validation.Affected if Project file open/import functionality is present and the version falls within the affected ranges.
-
Check for recent project filesSearch for .iab, .iap, or other project file extensions in user directories that may have been used with IAB. Review file modification dates.Affected if The environment contains IAB project files and the IAB version is within the affected ranges.
A user is affected if Integrated Architecture Builder version is 9.6.0.7 or earlier, or exactly 9.7.0.0 or 9.7.0.1, and the application processes project files.

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 dataUpgrade IAB to version 9.6.0.8 or later (for 9.6.x branch) or 9.7.0.2 or later (for 9.7.x branch). Consider network segmentation and disabling file import features until patched.
