Apache Tomcat 7.0.x < 7.0.17 Multiple Vulnerabilities

medium Nessus Network Monitor Plugin ID 5996


The remote web server is affected by multiple vulnerabilities.


According to its self-reported version number, the instance of Apache Tomcat 7.x listening on the remote host is prior to 7.0.17. It is, therefore, affected by the following vulnerabilities:

- An error handling issue exists related to the MemoryUserDatabase that allows user passwords to be disclosed through log files. (CVE-2011-2204)

- If loaded before other web applications, a malicious web application can potentially access or modify the web.xml, context.xml, and TLD files of other web applications on the system. (CVE-2011-2481)

- An input validation error exists that allows a local attacker to either bypass security or carry out denial of service attacks when the APR or NIO connectors are enabled. (CVE-2011-2526)

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


Upgrade to Apache Tomcat 7.0.19 or later. Note that versions 7.0.17 and 7.0.18 are not affected but were never officially released.
