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.

A vulnerability was found in Juniper Junos (Router Operating System). It has been classified as critical. Affected is an unknown code block of the component BGP UPDATE Message Handler. The manipulation with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as 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. This is going to have an impact on confidentiality, integrity, and availability.

The weakness was presented 10/08/2014 with Juniper as JSA10653 as confirmed advisory (Website). The advisory is available at kb.juniper.net. JSA10653 claims memory corruption possible but displays [7.8] AV:N/AC:L/Au:N/C:N/I:N/A:C but it must be [10.0] AV:N/AC:L/Au:N/C:C/I:C/A:C then. This vulnerability is traded as CVE-2014-3818 since 05/21/2014. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. The technical details are unknown and an exploit is not available. The advisory points out:

A BGP UPDATE containing a specifically crafted set of transitive attributes can cause corruption of memory ultimately leading to an RPD routing process crash and restart. The crash was only achieved through in-house routing protocol fuzz testing. This issue only affects routers supporting 4-byte AS numbers, introduced starting with Junos OS 9.1. Additionally, the router is only vulnerable if the BGP peer does not support 4-byte AS numbers.

The vulnerability scanner Nessus provides a plugin with the ID 78424 , which helps to determine the existence of the flaw in a target environment. It is .

Upgrading to version 11.4R11, 12.1R10, 12.1X44-D40, 12.1X46-D30, 12.1X47-D11, 12.1X47-D15, 12.1X48-D41, 12.1X48-D62, 12.2R8, 12.2X50-D70, 12.3R6, 13.1R4-S2, 13.1X49-D49, 13.1X50-D30, 13.2R4, 13.2X50-D20, 13.2X51-D25, 13.2X52-D15, 13.3R2 or 14.1R1 eliminates this vulnerability. A possible mitigation has been published immediately after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (96908) and Tenable (78424). See 67762, 67761, 67760 and 67759 for similar entries.
