Jason Kratzer has reported some vulnerabilities in JSPWiki, which can be exploited by malicious people to disclose system information and conduct cross-site scripting and script insertion attacks.
1) Input passed to the "group" and "members" parameters in NewGroup.jsp, to the "edittime" parameter in Edit.jsp, to the "edittime", "author" and "link" parameters in Comment.jsp, to the "loginname", "wikiname", "fullname" and "email" parameters in UserPreferences.jsp and Login.jsp, to the "r1" and "r2" parameters in Diff.jsp, and to the "redirect" parameter in Login.jsp is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
2) Input passed via the "changenote" parameter is not properly sanitised before being displayed. This can be exploited to insert arbitrary HTML and script code, which is executed in a user's browser session in context of an affected site when the information of a specially crafted page is being viewed via PageInfo.jsp.
3) An error within the processing of the version parameter included in HTTP requests for attachments can be exploited to disclose the full path of the application.
The vulnerabilities are reported in versions prior to 2.4.104.
