Cross-site scripting (XSS) vulnerability in PortalApp 4.0 allows remote attackers to inject arbitrary web script or HTML via the keywords parameter to (1) forums.asp and (2) content.asp.
PortalApp 4.0 does not require authentication for (1) forums.asp and (2) content.asp, which allows remote attackers to create and delete forums, topics, and replies.
PortalApp stores sensitive information under the web root with insufficient access control, which allows remote attackers to download a database via a direct request for 8691.mdb, a different vector than CVE-2004-1786.
