Amazon Linux AMI : tomcat8 (ALAS-2016-658)

Medium Nessus Plugin ID 89839

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

A directory traversal vulnerability in RequestUtil.java was discovered which allows remote authenticated users to bypass intended SecurityManager restrictions and list a parent directory via a /..
(slash dot dot) in a pathname used by a web application in a getResource, getResourceAsStream, or getResourcePaths call.
(CVE-2015-5174)

The Mapper component processes redirects before considering security constraints and Filters, which allows remote attackers to determine the existence of a directory via a URL that lacks a trailing / (slash) character. (CVE-2015-5345)

It was found that the expression language resolver evaluated expressions within a privileged code section. A malicious web application could use this flaw to bypass security manager protections. (CVE-2014-7810)

Solution

Run 'yum update tomcat8' to update your system.
