CVE-2019-16102
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 · uneditedSilver Peak EdgeConnect SD-WAN before 8.1.7.x has an SNMP service with a public value for rocommunity and trapcommunity.
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 confidenceThe Silver Peak EdgeConnect SD-WAN appliance exposes an SNMP service (versions 1/2c) with the default 'public' community string configured for both read-only (rocommunity) and trap (trapcommunity) roles. This hardcoded credential allows unauthenticated remote attackers to retrieve sensitive network topology, device configuration, and system information via standard SNMP queries, or potentially manipulate SNMP settings if write access is enabled.

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 Silver Peak EdgeConnect SD-WAN deviceQuery SNMP sysDescr.1 (or log into CLI and run 'show system info') to confirm the device is a Silver Peak Unity EdgeConnect SD-WAN applianceAffected if Device is confirmed as a Silver Peak EdgeConnect SD-WAN model
-
Check installed firmware versionQuery SNMP hrSWInstalledName or access CLI and run 'show version' to retrieve the exact firmware build numberAffected if Firmware version equals exactly 8.1.4.9_65644
-
Verify SNMP service is enabledCheck if UDP port 161 is listening (e.g., 'netstat -an | grep 161' or SNMP scan of the device)Affected if SNMP service is running and accessible on the network
-
Confirm default community string is activeSend an SNMP GET request using community string 'public' to snmp/sysDescr.1 or snmp/sysName.1Affected if SNMP queries succeed with the default 'public' community string (meaning unauthenticated access is possible)
The environment is affected if the device is a Silver Peak EdgeConnect SD-WAN running firmware version 8.1.4.9_65644 with SNMP enabled and responding to the default 'public' community string.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scopedUpgrade EdgeConnect firmware to version 8.1.7.x or later, and replace default SNMP community strings with unique, complex values (or migrate to SNMPv3 with authentication/encryption). If SNMP is not required, disable the service.
8.1.7.x or later
- 1. Upgrade Unity EdgeConnect SD-WAN firmware to version 8.1.7 or later to remediate the default SNMP community string vulnerability
