A security vulnerability exists in the Proxy Plug-in for certain Sun ONE and Java System Application Server products when the plug-in is used with a supported web server, such as Sun Java System Web Server, Apache Web Server or Microsoft Internet Information Server (IIS). This vulnerability may allow a "Man-in-the-Middle" condition to be exploited and possibly compromise data privacy between the client and the server.

Note: Though not impossible, it will be difficult to carry out this exploit from outside the firewall in front of the web server.

This issue can occur in the following releases:

SPARC Platform

• Sun ONE Application Server 7
• Sun Java System Application Server 7 2004Q2
• Sun Java System Application Server Enterprise Edition 8.1 2005 Q1 without (file-based) patch 119169-03 or (SVR4) patch 119166-11

    Unable to communicate with admin server, getting version locally.
    Version = Sun Java System Application Server Enterprise Edition 8.1
    (build b43-fcs)
    Command version executed successfully.

(Where <AS_INSTALL> is the installation directory of the Application Server)
