TITLE:
e107 Cross-Site Request Forgery and Script Insertion

SECUNIA ADVISORY ID:
SA34169

VERIFY ADVISORY:
http://secunia.com/advisories/34169/

DESCRIPTION:
Some vulnerabilities have been discovered in e107, which can be
exploited by malicious people to conduct cross-site request forgery
attacks and malicious users to conduct script insertion attacks.

1) The application allows users to perform certain actions via HTTP
requests without performing any validity checks to verify the
requests. This can be exploited to manipulate site settings (e.g.
modify user permissions) by enticing a logged in administrator to
visit a malicious web page.

2) Input passed to the "userclass_name" and "userclass_description"
parameters in e107_admin/userclass2.php is not properly sanitised
before being used. This can be exploited to insert arbitrary HTML and
script code, which may be executed in a user's browser session in the
context of an affected site if the malicious user class is viewed.

The vulnerabilities are confirmed in version 0.7.14. Other versions
may also be affected.

SOLUTION:
Do not visit untrusted web sites while logged on to the application.
Edit the source code to ensure that input is properly sanitised.
