A vulnerability was found in Juniper Junos (Router Operating System) (the affected version unknown). It has been rated as problematic. Affected by this issue is an unknown part of the component NG-mVPN. The manipulation as part of a Malformed Packet leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. Impacted is availability. CVE summarizes:

An unexpected status return value weakness in the Next-Generation Multicast VPN (NG-mVPN) service of Juniper Networks Junos OS allows attacker to cause a Denial of Service (DoS) condition and core the routing protocol daemon (rpd) process when a specific malformed IPv4 packet is received by the device running BGP. This malformed packet can be crafted and sent to a victim device including when forwarded directly through a device receiving such a malformed packet, but not if the malformed packet is first de-encapsulated from an encapsulated format by a receiving device. Continued receipt of the malformed packet will result in a sustained Denial of Service condition. This issue affects: Juniper Networks Junos OS 15.1 versions prior to 15.1F6-S12, 15.1R7-S2; 15.1X49 versions prior to 15.1X49-D150 on SRX Series; 15.1X53 versions prior to 15.1X53-D68, 15.1X53-D235, 15.1X53-D495, 15.1X53-D590; 16.1 versions prior to 16.1R3-S10, 16.1R4-S12, 16.1R6-S6, 16.1R7-S2; 16.2 versions prior to 16.2R2-S7; 17.1 versions prior to 17.1R2-S9, 17.1R3; 17.2 versions prior to 17.2R1-S7, 17.2R2-S6, 17.2R3; 17.3 versions prior to 17.3R2-S4, 17.3R3.

The weakness was released 10/09/2019. This vulnerability is handled as CVE-2019-0066 since 10/11/2018. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. There are neither technical details nor an exploit publicly available. The current price for an exploit might be approx. USD $5k-$25k (estimation calculated on 01/05/2024).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
