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 10.4 before 10.4R16, 11.4 before 11.4R10, 12.1R before 12.1R8-S2, 12.1X44 before 12.1X44-D30, 12.1X45 before 12.1X45-D20, 12.1X46 before 12.1X46-D10, 12.2 before 12.2R7, 12.3 before 12.3R4-S2, 13.1 before 13.1R3-S1, 13.2 before 13.2R2, and 13.3 before 13.3R1 allows remote attackers to cause a denial of service (rdp crash) via a large BGP UPDATE message which immediately triggers a withdraw message to be sent, as demonstrated by a long AS_PATH and a large number of BGP Communities.

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

Denial of service vulnerability in Juniper Junos BGP routing daemon (rpd) where specially crafted large BGP UPDATE messages with long AS_PATH and many BGP Communities immediately followed by a withdraw message trigger a crash. This affects multiple Junos branches from 10.4 through 13.3.

MitigationUpgrade to the fixed Junos versions (10.4R16, 11.4R10, 12.1R8-S2, 12.1X44-D30, 12.1X45-D20, 12.1X46-D10, 12.2R7, 12.3R4-S2, 13.1R3-S1, 13.2R2, 13.3R1 or later). As interim mitigation, filter or rate-limit BGP updates from untrusted peers and implement AS_PATH and community length limits.

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 the Junos version
    Run 'show version' or 'request system version' on the Junos device to obtain the installed software version.
    Affected if The installed version matches one of the affected versions: 10.4, 11.4, 12.1, 12.2, 12.3, 13.1, 13.2, or 13.3 (including specific point releases listed in the CVE).
  2. Verify BGP routing daemon is enabled
    Run 'show bgp summary' or 'show routing-options dynamic-tcp-authentication' to confirm the rpd BGP process is active and configured.
    Affected if BGP is enabled and the device participates in BGP peering, as the vulnerability requires processing of BGP UPDATE messages.
  3. Confirm BGP peer configuration exists
    Run 'show bgp neighbor' to list configured BGP peers.
    Affected if There are configured BGP peers, particularly untrusted or external peers (eBGP), as the attack vector involves specially crafted messages from peers.
  4. Check for rpd crash logs
    Run 'show system core-dumps' and review system logs for recent rpd crashes or restarts, particularly those occurring after processing BGP updates.
    Affected if There are recent rpd crashes or restarts that coincide with BGP update processing, which may indicate exploitation of this vulnerability.

A user is affected if they run a vulnerable Junos version (10.4 through 13.3) with BGP enabled and have configured BGP peers, as the vulnerability is triggered by specially crafted BGP UPDATE messages from those peers.

Mitigation

Upgrade to the fixed Junos versions (10.4R16, 11.4R10, 12.1R8-S2, 12.1X44-D30, 12.1X45-D20, 12.1X46-D10, 12.2R7, 12.3R4-S2, 13.1R3-S1, 13.2R2, 13.3R1 or later). As interim mitigation, filter or rate-limit BGP updates from untrusted peers and implement AS_PATH and community length limits.
