TITLE:
LetoDMS Local File Inclusion and Cross-Site Request Forgery
Vulnerabilities

SECUNIA ADVISORY ID:
SA38237

VERIFY ADVISORY:
http://secunia.com/advisories/38237/

DESCRIPTION:
Some vulnerabilities have been discovered in LetoDMS, which can be
exploited by malicious users and malicious people to disclose
sensitive information and by malicious people to conduct cross-site
request forgery attacks.

1) Input passed to the "lang" parameter in op/op.Login.php 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 and URL-encoded NULL bytes.

2) 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 e.g. change user details, delete
users, delete documents, delete folders, add arbitrary categories,
add arbitrary groups, change folder access permissions, change notify
list for folders, or move folders by tricking a logged in user into
visiting a malicious web site.

The vulnerabilities are confirmed in version 1.7.2. Other versions
may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly verified. Do
not browse untrusted websites or follow untrusted links while logged
in to the application.
