Synopsis
The remote Apache Tomcat server is affected by multiple vulnerabilities.
Description
According to its self-reported version number, the Apache Tomcat service running on the remote host is 6.0.x prior to 6.0.45. It is, therefore, affected by multiple vulnerabilities :
- An information disclosure vulnerability exists in the getResource(), getResourceAsStream(), and getResourcePaths() ServletContext methods due to a failure to properly sanitize user-supplied input. An unauthenticated, remote attacker can exploit this, via a crafted path traversal request, to gain access to the listing of directory contents. (CVE-2015-5174)
- An information disclosure vulnerability exists due to a failure to enforce access restrictions when handling directory requests that are missing trailing slashes. An unauthenticated, remote attacker can exploit this to enumerate valid directories. (CVE-2015-5345)
- An information disclosure vulnerability exists that allows a specially crafted web application to load the StatusManagerServlet. An attacker can exploit this to gain unauthorized access to a list of all deployed applications and a list of the HTTP request lines for all requests currently being processed. (CVE-2016-0706)
- A security bypass vulnerability exists due to a flaw in the StandardManager, PersistentManager, and cluster implementations that is triggered when handling persistent sessions. An unauthenticated, remote attacker can exploit this, via a crafted object in a session, to bypass the security manager and execute arbitrary code.
(CVE-2016-0714)
Note that Nessus has not attempted to exploit these issues but has instead relied only on the application's self-reported version number.
Solution
Upgrade to Apache Tomcat version 6.0.45 or later.
