Detailsinfo

A vulnerability classified as problematic has been found in Juniper Junos up to 12.1x46 on SRX (Router Operating System). Affected is an unknown code of the component flowd Service. The manipulation as part of a URL 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 availability. CVE summarizes:

The Enhanced Web Filtering (EWF) in Juniper Junos before 10.4R15, 11.4 before 11.4R9, 12.1 before 12.1R7, 12.1X44 before 12.1X44-D20, 12.1X45 before 12.1X45-D10, and 12.1X46 before 12.1X46-D10, as used in the SRX Series services gateways, allows remote attackers to cause a denial of service (flow daemon crash and restart) via a crafted URL.

The weakness was published 04/09/2014 as JSA10622 / PR 877830 / KB16765 as confirmed advisory (Website). The advisory is available at kb.juniper.net. The public release has been coordinated with the vendor. This vulnerability is traded as CVE-2014-2714 since 04/01/2014. 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 certain type of URL can cause the flow daemon (flowd) process to crash and restart. Repeated crashes of the flowd process can represent a sustained denial of service condition for SRX Series devices.
