Some vulnerabilities have been reported in JFFNMS, which can be exploited by malicious people to disclose sensitive information, manipulate certain data, and conduct cross-site scripting and SQL injection attacks.
1) Input passed to the "user" parameter in auth.php 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 to the "user" and "pass" parameters in auth.php is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
3) It is possible to view certain system information returned by the "phpinfo()" function by accessing the admin/adm/test.php script directly.
4) It is possible to view and modify configuration settings via the "admin/setup.php" script.
The vulnerabilities are reported in version 0.8.3. Other versions may also be affected.
Solution: Vulnerability #3 and the "user" parameter in vulnerability #2 have been fixed in version 0.8.4-pre2. Grant only trusted users access to the application.
Provided and/or discovered by: Tim Brown and an anonymous person.
