CVE-2012-3021
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 · uneditedrifsrvd.exe in the Remote Interface Service in GE Intelligent Platforms Proficy Real-Time Information Portal 2.6 through 3.5 SP1 allows remote attackers to cause a denial of service (memory corruption and service crash) or possibly execute arbitrary code via long input data, a different vulnerability than CVE-2012-3010 and CVE-2012-3026.
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.

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 if rifsrvd.exe service is installedOpen Windows Services console (services.msc) and look for a service related to 'Remote Interface Service' or 'rifsrvd', or use command 'sc queryex type= service state= all' to list all services and search for rifsrvd or 'Real Time Information Portal'Affected if The rifsrvd.exe service is found and running on the system
-
Determine installed GE Proficy Real-Time Information Portal versionCheck Program Files for 'GE Intelligent Platforms' or 'Proficy' folder containing 'Real-Time Information Portal' and view the version property of the main executable, or check Add/Remove Programs for the installed versionAffected if The installed version matches 2.6, 3.0, or 3.5 (or falls within 2.6-3.5 SP1 range)
-
Verify rifsrvd.exe process is activeOpen Task Manager or use command 'tasklist /FI "IMAGENAME eq rifsrvd.exe"' to check if the Remote Interface Service process is runningAffected if rifsrvd.exe process is running
-
Check network exposure of Remote Interface ServiceReview firewall rules and network configuration to determine if port used by rifsrvd.exe (typically RPC or configured port) is exposed to untrusted networks, or use 'netstat -ano' to identify listening ports associated with the serviceAffected if The Remote Interface Service port is listening on an exposed network interface accessible from untrusted networks
The system is affected if GE Proficy Real-Time Information Portal versions 2.6, 3.0, or 3.5 is installed with the rifsrvd.exe Remote Interface Service running and accessible on the network.

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 vendor patches or upgrade to a patched version of the affected software; restrict network access to the Remote Interface Service to reduce attack surface.
