"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 has not tested for these issues but has instead
relied only on the application's self-reported version number.");
