Detailsinfo

A vulnerability, which was classified as problematic, was found in Apache Tomcat Security Manager up to 6.0.39/7.0.53/8.0.5 (Application Server Software). Affected is some unknown functionality of the component XSLT Handler. The manipulation with an unknown input leads to a access control vulnerability. CWE is classifying the issue as CWE-264. This is going to have an impact on confidentiality, and integrity. CVE summarizes:

java/org/apache/catalina/servlets/DefaultServlet.java in the default servlet in Apache Tomcat before 6.0.40, 7.x before 7.0.53, and 8.x before 8.0.4 does not properly restrict XSLT stylesheets, which allows remote attackers to bypass security-manager restrictions and read arbitrary files via a crafted web application that provides an XML external entity declaration in conjunction with an entity reference, related to an XML External Entity (XXE) issue.

The bug was discovered 02/27/2014. The weakness was released 03/27/2014 with Tomcat Security Team as Fixed in Apache Tomcat 8.0.5 as confirmed release notes (Website). The advisory is available at tomcat.apache.org. This vulnerability is traded as CVE-2014-0096 since 12/03/2013. It is possible to launch the attack remotely. A authentication is required for exploitation. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1068 by the MITRE ATT&CK project. The advisory points out:

The default servlet allows web applications to define (at multiple levels) an XSLT to be used to format a directory listing. When running under a security manager, the processing of these was not subject to the same constraints as the web application. This enabled a malicious web application to bypass the file access constraints imposed by the security manager via the use of external XML entities.

The vulnerability was handled as a non-public zero-day exploit for at least 28 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 79670 (F5 Networks BIG-IP : Apache Tomcat vulnerability (SOL15428)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family F5 Networks Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 185089 (HP-UX Apache Server Suite Multiple Vulnerabilities (HPSBUX03102)).

Upgrading to version 6.0.41, 7.0.54 or 8.0.8 eliminates this vulnerability. A possible mitigation has been published immediately after the disclosure of the vulnerability. The release notes contains the following remark:

This was fixed in revisions 1578610 and 1578611.
