CVE-2016-0860
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 · uneditedBuffer overflow in the BwpAlarm subsystem in Advantech WebAccess before 8.1 allows remote attackers to cause a denial of service via a crafted RPC request.
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 confidenceBuffer overflow vulnerability in the BwpAlarm subsystem of Advantech WebAccess versions prior to 8.1. Remote attackers can exploit this via specially crafted RPC requests to cause a denial of service. The vulnerability is network-exploitable with low complexity and no authentication required.

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 Advantech WebAccess is installedCheck for WebAccess installation directories (commonly in C:\Advantech\WebAccess or C:\Program Files\Advantech\WebAccess) or look for the WebAccess service in Windows ServicesAffected if Advantech WebAccess software is found on the system
-
Determine the installed WebAccess versionRight-click the WebAccess executable or DLL file, select Properties, and check the Version tab. Alternatively, check the About or Version information within the WebAccess application interface if accessibleAffected if The version displayed is 8.0 or earlier (any version less than 8.1)
-
Verify if the BwpAlarm subsystem is presentCheck for the presence of BwpAlarm-related executables, DLLs, or services within the WebAccess installation directory. Look for files named BwpAlarm or similar patterns in the installation folderAffected if The BwpAlarm subsystem files or service exist in the WebAccess installation
-
Confirm RPC service availability for WebAccessCheck if the RPC service (typically using DCOM or port 4592/4593 commonly used by WebAccess RPC) is listening and accessible on the network. Use netstat -an to check for listening ports associated with WebAccessAffected if RPC ports for WebAccess are open and listening on network interfaces
A system is affected if Advantech WebAccess version 8.0 or earlier is installed with the BwpAlarm subsystem present and accessible, particularly if RPC services are exposed 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 dataUpgrade Advantech WebAccess to version 8.1 or later to remediate the buffer overflow vulnerability. If immediate upgrade is not feasible, consider network segmentation to restrict RPC access to the affected subsystem.
