Description

An Improper Input Validation vulnerability in Juniper Tunnel Driver (jtd) and ICMP module of Juniper Networks Junos OS Evolved allows an unauthenticated attacker within the MPLS administrative domain to send specifically crafted packets to the Routing Engine (RE) to cause a Denial of Service (DoS). 

When specifically crafted transit MPLS IPv4 packets are received by the Packet Forwarding Engine (PFE), these packets are internally forwarded to the RE. Continued receipt of these packets may create a sustained Denial of Service (DoS) condition.

This issue affects Juniper Networks Junos OS:

  • All versions before 21.2R3-S8-EVO;
  • from 21.4-EVO before 21.4R3-S6-EVO;
  • from 22.2-EVO before 22.2R3-S4-EVO;
  • from 22.3-EVO before 22.3R3-S3-EVO;
  • from 22.4-EVO before 22.4R3-EVO;
  • from 23.2-EVO before 23.2R2-EVO.
  • from 23.4-EVO before 23.4R1-S1-EVO.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
