Secunia

A weakness and some vulnerabilities have been reported in Ringtail CaseBook, which can be exploited by malicious people to gain knowledge of certain information and conduct cross-site scripting attacks.

1) An error caused due to the application returning different error responses depending on whether or not a valid username is supplied, can can be exploited to enumerate valid usernames.

2) Input passed to the "user" parameter in "login.asp" isn't 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.

3) Input passed to the "users" parameter in "login.asp" isn't 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.

4) Input passed to the "inline" parameter in "riv_install.asp" 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.
