  desc["english"] = "

  Overview: Apache Tomcat Server is running on this host and that is prone to
  security bypass vulnerability.

  Vulnerability Insight:
  Flaw in the application is due to the synchronisation problem when checking
  IP addresses. This could allow user from a non permitted IP address to gain
  access to a context that is protected with a valve that extends
  RemoteFilterValve including the standard RemoteAddrValve and RemoteHostValve
  implementations.

  Impact: Successful attempt could lead to remote code execution and attacker
  can gain access to context of the filtered value.

  Impact Level: Application

  Affected Software/OS:
  Apache Tomcat version 4.1.x - 4.1.31, and 5.5.0

  Fix: Upgrade to Apache Tomcat version 4.1.32, or 5.5.1, or later,
  http://archive.apache.org/dist/tomcat/
