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 WSO2 Carbon 4.4.5. It has been classified as problematic. Affected is an unknown part of the file downloadgz-ajaxprocessor.jsp. The manipulation of the argument logFile with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on confidentiality, and integrity. CVE summarizes:

Directory traversal vulnerability in the LogViewer Admin Service in WSO2 Carbon 4.4.5 allows remote authenticated administrators to read arbitrary files via a .. (dot dot) in the logFile parameter to downloadgz-ajaxprocessor.jsp.

The bug was discovered 08/13/2016. The weakness was shared 02/17/2017 by John Page (hyp3rlinx) as confirmed posting (Bugtraq). The advisory is shared for download at securityfocus.com. This vulnerability is traded as CVE-2016-4314 since 04/27/2016. The exploitability is told to be easy. It is possible to launch the attack remotely. A authentication is necessary for exploitation.
