-- Vulnerability Details:
This vulnerability allows remote attackers to execute remote code on
vulnerable installations of IBM Cognos Server. Proper authentication is
not required to exploit this vulnerability.

The specific flaw exists due to a hidden manager-level account with a
default password defined in the user configuration of the bundled Tomcat
server. This server can be reached via HTTP on TCP port 19300. A
malicious attacker can use this account to manage or deploy a servlet
onto the server. By abusing this ability a remote attacker can execute
arbitrary code under the context of the user running the Tomcat server.

-- Vendor Response:
IBM has issued an update to correct this vulnerability. More
