Juniper Junos up to 13.2 BGP FlowSpec code

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability was found in Juniper Junos up to 13.2 (Router Operating System). It has been classified as problematic. This affects an unknown part of the component BGP FlowSpec Handler. The manipulation with an unknown input leads to a code vulnerability. CWE is classifying the issue as CWE-17. This is going to have an impact on availability.

The weakness was released 01/15/2015 as JSA10670 as confirmed advisory (Website). It is possible to read the advisory at kb.juniper.net. The advisory contains:

This issue was found during negative protocol testing and has not been seen in a production network.
This vulnerability is uniquely identified as CVE-2014-6386 since 09/11/2014. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. The technical details are unknown and an exploit is not publicly available. The advisory points out:
Receipt of a malformed BGP FlowSpec prefix may cause the router to trigger an assert (program??matic crash) when detecting a certain specification violation. Rather than simply flagging, logging, and/or dropping the packet, the routing process daemon (rpd) will crash and restart. ?

The vulnerability scanner Nessus provides a plugin with the ID 80958 , which helps to determine the existence of the flaw in a target environment. It is .

Upgrading to version 11.4R8, 12.1X44-D35, 12.1X45-D25, 12.1X46-D20, 12.1X47-D10, 12.2R9, 12.3R2-S3, 12.3R3, 13.1R4 or 13.2R1 eliminates this vulnerability. The advisory contains the following remark:

Only configure the FlowSpec NLRI to a known trusted BGP peer. Using MD5 authentication is also a good security practice. In addition to the recommendations listed above, it is good security practice to limit the exploitable attack surface of critical infrastructure networking equipment. Use access lists or firewall filters to limit access to the router via FlowSpec only from trusted, administrative networks or hosts.

The vulnerability is also documented in the databases at X-Force (100062), Tenable (80958), SecurityFocus (BID 72067†), SecurityTracker (ID 1031548†) and Vulnerability Center (SBV-48066†). Entries connected to this vulnerability are available at VDB-68632 and VDB-68630. Statistical analysis made it clear that VulDB provides the best quality for vulnerability data.
