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 · unedited
Juniper Junos OS 12.1X44 before 12.1X44-D50, 12.1X46 before 12.1X46-D35, 12.1X47 before 12.1X47-D25, 12.3 before 12.3R9, 12.3X48 before 12.3X48-D10, 13.2 before 13.2R7, 13.3 before 13.3R5, 14.1R3 before 14.1R3-S2, 14.1 before 14.1R4, 14.2 before 14.2R2, and 15.1 before 15.1R1 allows remote attackers to cause a denial of service (NULL pointer dereference and RDP crash) via a large number of BGP-VPLS advertisements with updated BGP local preference values.

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 confidence

A NULL pointer dereference vulnerability exists in the Routing Protocol Process (RDP) of Juniper Junos OS. When processing a large number of BGP-VPLS advertisements with updated BGP local preference values, the RDP crashes due to the NULL pointer dereference, causing a denial of service.

MitigationUpgrade Junos OS to versions beyond the fixed releases (12.1X44-D50, 12.1X46-D35, 12.1X47-D25, 12.3R9, 12.3X48-D10, 13.2R7, 13.3R5, 14.1R3-S2, 14.1R4, 14.2R2, or 15.1R1). If immediate upgrade is not possible, consider filtering or rate-limiting suspicious BGP-VPLS updates as a temporary workaround.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed Junos OS version
    Execute 'show version' or 'show system information' on the Junos device CLI
    Affected if The installed version matches any of: 12.1X44, 12.1X46, 12.1X47, 12.3, 12.3X48, 13.2, 13.3, 14.1, 14.1X53, 14.2, or 15.1
  2. Verify BGP-VPLS is configured
    Run 'show configuration protocols bgp' and search for 'family vpls' or 'family inet-vpls' under the BGP configuration hierarchy
    Affected if BGP-VPLS family is enabled and configured on the device
  3. Confirm RDP process stability
    Execute 'show system crash' or review the system log file via 'show log messages' for recent routing protocol daemon (rpd) crash entries
    Affected if The rpd process has crashed with a NULL pointer dereference error, or crash dumps reference the RDP component

The device is affected if it runs a vulnerable Junos version AND has BGP-VPLS configured, potentially showing rpd crash evidence in system logs.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade Junos OS to versions beyond the fixed releases (12.1X44-D50, 12.1X46-D35, 12.1X47-D25, 12.3R9, 12.3X48-D10, 13.2R7, 13.3R5, 14.1R3-S2, 14.1R4, 14.2R2, or 15.1R1). If immediate upgrade is not possible, consider filtering or rate-limiting suspicious BGP-VPLS updates as a temporary workaround.
