Summaryinfo

A vulnerability classified as critical was found in Apache Tomcat. This issue affects some unknown processing of the component JSP Upload Handler. Executing a manipulation can lead to code injection. This vulnerability is tracked as CVE-2013-4444. No exploit exists. Upgrading the affected component is advised.

Detailsinfo

A vulnerability has been found in Apache Tomcat (Application Server Software) and classified as critical. This vulnerability affects an unknown function of the component JSP Upload Handler. The manipulation with an unknown input leads to a code injection vulnerability. The CWE definition for the vulnerability is CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

Unrestricted file upload vulnerability in Apache Tomcat 7.x before 7.0.40, in certain situations involving outdated java.io.File code and a custom JMX configuration, allows remote attackers to execute arbitrary code by uploading and accessing a JSP file.

The weakness was disclosed 09/10/2014 by Pierre Ernst with Vmware as Bug CVE-201 as confirmed bug report (Bugzilla). The advisory is available at bugzilla.redhat.com. This vulnerability was named CVE-2013-4444 since 06/12/2013. The attack can be initiated remotely. The successful exploitation requires a single authentication. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1059 by the MITRE ATT&CK project. The advisory points out:

In very limited circumstances, it was possible for an attacker to upload a malicious JSP to a Tomcat server and then trigger the execution of that JSP. While Remote Code Execution would normally be viewed as a critical vulnerability, the circumstances under which this is possible are, in the view of the Tomcat security team, sufficiently limited that this vulnerability is viewed as important.

The vulnerability scanner Nessus provides a plugin with the ID 66428 (Apache Tomcat 7.0.x < 7.0.40 Multiple Vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Web Servers. The commercial vulnerability scanner Qualys is able to test this issue with plugin 175599 (Debian Security Update for tomcat7 (DSA 3447-1)). The advisory illustrates:

For this attack to succeed all of the following requirements must be met: 1. Using Oracle Java 1.7.0 update 25 or earlier (or any other Java implementation where java.io.File is vulnerable to null byte injection). 2. A web application must be deployed to a vulnerable version of Tomcat. 3. The web application must use the Servlet 3.0 File Upload feature. 4. A file location within a deployed web application must be writeable by the user the Tomcat process is running as. The Tomcat security documentation recommends against this. 5. A custom listener for JMX connections (e.g. the JmxRemoteListener that is not enabled by default) must be configured and be able to load classes from Tomcat's common class loader (i.e. the custom JMX listener must be placed in Tomcat's lib directory). 6. The custom JMX listener must be bound to an address other than localhost for a remote attack (it is bound to localhost by default). If the custom JMX listener is bound to localhost, a local attack will still be possible. Note that requirements 2 and 3 may be replaced with the following requirement: 7. A web application is deployed that uses Apache Commons File Upload 1.2.1 or earlier.

Upgrading to version 1470437 eliminates this vulnerability. The bug report contains the following remark:

This issue did not affect the versions of tomcat as shipped with Red Hat Enterprise Linux 5, 6, or 7 nor the versions of tomcat as shipped with JBoss Enterprise Web Server.

The vulnerability is also documented in the databases at X-Force (95876), Tenable (66428), SecurityFocus (BID 69728†), SecurityTracker (ID 1030834†) and Vulnerability Center (SBV-46086†). The entries VDB-13218, VDB-56096, VDB-56006 and VDB-56005 are pretty similar. Once again VulDB remains the best source for vulnerability data.
