Apache Tomcat < 4.1.40 / 5.5.28 / 6.0.20 Multiple Vulnerabilities

Medium Nessus Plugin ID 46753


The remote Apache Tomcat server is affected by multiple vulnerabilities.


According to its self-reported version number, the Apache Tomcat server listening on the remote host is prior to 4.1.40, 5.5.28, or 6.0.20. It is, therefore, affected by the following vulnerabilities :

- The remote server is affected by a directory traversal vulnerability if a RequestDispatcher obtained from a Request object is used. A specially crafted value for a request parameter can be used to access potentially sensitive configuration files or other files, e.g., files in the WEB-INF directory. (CVE-2008-5515)

- The remote server is affected by a denial of service vulnerability if configured to use the Java AJP connector. An attacker can send a malicious request with invalid headers which causes the AJP connector to be put into an error state for a short time. This behavior can be used as a denial of service attack. (CVE-2009-0033)

- The remote server is affected by a username enumeration vulnerability if configured to use FORM authentication along with the 'MemoryRealm', 'DataSourceRealm', or 'JDBCRealm' authentication realms. (CVE-2009-0580)

- The remote server is affected by a script injection vulnerability if the example JSP application, 'cal2.jsp', is installed. An unauthenticated, remote attacker can exploit this issue to inject arbitrary HTML or script code into a user's browser to be executed within the security context of the affected site.

- The remote server is vulnerable to unauthorized modification of 'web.xml', 'context.xml', or TLD files of arbitrary web applications. This vulnerability allows the XML parser, used to process the XML and TLD files, to be replaced. (CVE-2009-0783)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.


Upgrade to Apache Tomcat version 4.1.40 / 5.5.28 / 6.0.20 or later.
