EulerOS 2.0 SP1 : tomcat (EulerOS-SA-2016-1049)

high Nessus Plugin ID 99812

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the tomcat packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 - The Expression Language (EL) implementation in Apache Tomcat 6.x before 6.0.44, 7.x before 7.0.58, and 8.x before 8.0.16 does not properly consider the possibility of an accessible interface implemented by an inaccessible class, which allows attackers to bypass a SecurityManager protection mechanism via a web application that leverages use of incorrect privileges during EL evaluation.(CVE-2014-7810)

 - Session fixation vulnerability in Apache Tomcat 7.x before 7.0.66, 8.x before 8.0.30, and 9.x before 9.0.0.M2, when different session settings are used for deployments of multiple versions of the same web application, might allow remote attackers to hijack web sessions by leveraging use of a requestedSessionSSL field for an unintended request, related to CoyoteAdapter.java and Request.java.(CVE-2015-5346)

 - Apache Tomcat through 8.5.4, when the CGI Servlet is enabled, follows RFC 3875 section 4.1.18 and therefore does not protect applications from the presence of untrusted client data in the HTTP_PROXY environment variable, which might allow remote attackers to redirect an application's outbound HTTP traffic to an arbitrary proxy server via a crafted Proxy header in an HTTP request, aka an 'httpoxy' issue. NOTE: the vendor states 'A mitigation is planned for future releases of Tomcat, tracked as CVE-2016-5388' in other words, this is not a CVE ID for a vulnerability.(CVE-2016-5388)

 - It was discovered that the Tomcat packages installed configuration file /usr/lib/tmpfiles.d/tomcat.conf writeable to the tomcat group. A member of the group or a malicious web application deployed on Tomcat could use this flaw to escalate their privileges.(CVE-2016-5425)

 - It was discovered that the Tomcat packages installed certain configuration files read by the Tomcat initialization script as writeable to the tomcat group.
 A member of the group or a malicious web application deployed on Tomcat could use this flaw to escalate their privileges.(CVE-2016-6325)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected tomcat packages.
