Amazon Linux AMI : tomcat6 (ALAS-2016-681)

high Nessus Plugin ID 90274

Language:

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)

The session-persistence implementation was discovered to mishandle session attributes, which allows remote authenticated users to bypass intended SecurityManager restrictions and execute arbitrary code in a privileged context via a web application that places a crafted object in a session. (CVE-2016-0714)

It was discovered that org.apache.catalina.manager.StatusManagerServlet was not placed on the org/apache/catalina/core/RestrictedServlets.properties list, which allows remote authenticated users to bypass intended SecurityManager restrictions and read arbitrary HTTP requests, and consequently discover session ID values, via a crafted web application.
(CVE-2016-0706)

Solution

Run 'yum update tomcat6' to update your system.
