CVE-2017-8020
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 · uneditedAn issue was discovered in EMC ScaleIO 2.0.1.x. A buffer overflow vulnerability in the SDBG service may potentially allow a remote unauthenticated attacker to execute arbitrary commands with root privileges on an affected server.
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 ScaleIO installation and versionRun command to query installed ScaleIO version, such as checking RPM/Deb packages with 'rpm -qa | grep -i scaleio' or inspecting installation directories for version filesAffected if The installed version is 2.0.1.0, 2.0.1.1, 2.0.1.2, or 2.0.1.3
-
Locate the SDBG serviceCheck for the SDBG binary or service - common paths include /opt/scaleio/sdbg or check running processes with 'ps aux | grep -i sdbg'Affected if The SDBG service is present on the system
-
Verify SDBG service is runningCheck if the SDBG process is active by running 'ps aux | grep sdbg' or checking systemd/system service statusAffected if The SDBG process is currently running
-
Check SDBG network exposureInspect listening ports and firewall rules to determine if SDBG service is exposed to network access - use 'netstat -tlnp | grep sdbg' or 'ss -tlnp' to identify listening ports and interfacesAffected if SDBG service is listening on a network-accessible interface (0.0.0.0 or external IP) rather than only localhost
You are affected if ScaleIO version is exactly 2.0.1.0, 2.0.1.1, 2.0.1.2, or 2.0.1.3 AND the SDBG service is running and network-accessible.

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 available vendor patches for ScaleIO 2.0.1.x. If patches are unavailable, restrict network access to the SDBG service and consider disabling it if not required for operations.
