CVE reference:CVE-2006-0439
CVE-2006-0440


Description:
Aliaksandr Hartsuyeu has discovered a security issue in Text Rider, which can be exploited by malicious people to disclose sensitive information and potentially compromise a vulnerable system.

The problem is that user credentials are stored in the "data/userlist.txt" file inside the web root. This can be exploited to disclose usernames and encrypted passwords.

This can further be exploited to access the administration section (cookie-based authentication uses encrypted passwords) where arbitrary files can be uploaded to a location inside the web root. It is also possible to edit config.php and insert arbitrary PHP code.

The security issue has been confirmed in version 2.4. Other versions may also be affected.

Solution:
Restrict web access to the "data" directory (e.g. with a .htaccess file).

Provided and/or discovered by:
Aliaksandr Hartsuyeu
