CVE-2019-16101
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 allows remote attackers to obtain potentially sensitive stack traces by sending incorrect JSON data to the REST API, such as the rest/json/banners URI.
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 · moderate confidenceThe Silver Peak EdgeConnect SD-WAN REST API does not properly handle malformed JSON input, causing the application to return verbose error messages including full stack traces. Attackers can send incorrect JSON data (e.g., to /rest/json/banners) to trigger these errors and gather potentially sensitive implementation details about the system.

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.
-
Check EdgeConnect firmware versionAccess the device CLI or admin web interface and run 'show version' or check the firmware version displayed in the system information pageAffected if The installed version is 8.1.4.9_65644 (exact match)
-
Verify REST API endpoint accessibilityAttempt to reach the REST API endpoints (e.g., GET https://<device>/rest/json/banners) from a network locationAffected if The REST API is reachable from untrusted networks (not restricted to internal networks)
-
Test for verbose error responseSend a malformed JSON request to the REST API, for example: curl -X POST https://<device>/rest/json/banners -d '{invalid json}' and observe the responseAffected if The response includes full stack traces, Java exception details, or internal implementation information
You are affected if your EdgeConnect firmware is version 8.1.4.9_65644 AND the REST API is accessible AND sending malformed JSON returns verbose error messages with stack traces.
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.
From vendor dataUpgrade to EdgeConnect version 8.1.7.x or later which addresses the improper error handling. As a temporary measure, restrict access to the REST API to trusted internal networks only.
