CVE-2017-2308
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 XML External Entity Injection vulnerability in Juniper Networks Junos Space versions prior to 16.1R1 may allow an authenticated user to read arbitrary files on the device.
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 confidenceThis is an XML External Entity Injection (XXE) vulnerability in Juniper Networks Junos Space network management platform. An authenticated attacker can craft malicious XML requests containing external entity references that the vulnerable XML parser processes, allowing arbitrary file read access on the affected device.

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.
-
Confirm Junos Space installationIdentify if Junos Space network management platform is deployed in your environment. This is typically a standalone appliance or virtual machine used for network infrastructure management.Affected if Junos Space is installed and is version 16.1 or earlier
-
Determine installed Junos Space versionAccess the Junos Space web interface (usually via HTTPS) and navigate to the About or System Information page to view the software version. Alternatively, use the CLI and run 'show version' or 'show software version' if you have CLI access.Affected if The displayed version is 16.1 or any version prior to 16.1R1
-
Verify XML processing is enabledCheck if Junos Space XML API or XML processing features are active. This is typically enabled by default as it is required for the network management functionality. Look for XML API endpoints or XML-related services in the system configuration.Affected if XML processing features are enabled (this is the default configuration)
-
Confirm authentication mechanismsReview the Junos Space authentication configuration to determine what user authentication methods are configured (local database, LDAP, RADIUS, etc.) and verify which authenticated users have access to XML functionality.Affected if Authenticated users have access to XML request functionality
Your environment is affected if Junos Space version is 16.1 or earlier AND XML processing features are enabled, which allows an authenticated attacker to exploit XXE and read arbitrary files on the device.
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 Junos Space to version 16.1R1 or later to obtain the patch for this vulnerability. As a compensating control, disable unnecessary XML processing features and restrict access to trusted authenticated users only.
