TITLE:
Testlink Cross-Site Scripting and File Inclusion Vulnerabilities

SECUNIA ADVISORY ID:
SA38201

VERIFY ADVISORY:
http://secunia.com/advisories/38201/

DESCRIPTION:
Prashant Khandelwal has discovered some vulnerabilities in Testlink,
which can be exploited by malicious users to disclose sensitive
information and by malicious people to conduct cross-site scripting
attacks.

1) Input passed to the "locale" parameter in
lib/usermanagement/userInfo.php (if "id", "firstName", "lastName",
"emailAddress", and "editUser" are set) is not properly verified
before being used to include files. This can be exploited to include
arbitrary files from local resources via directory traversal
attacks.

2) Input passed to the "order_by_role_dir", "order_by_login_dir", and
"user_order_by" parameters to lib/usermanagement/usersView.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.

The vulnerabilities are confirmed in version 1.8.5. Other versions
may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly verified and
sanitised.
