CVE reference:CVE-2008-5486
CVE-2008-5487


Description:
Some vulnerabilities have been reported in TurnkeyForms Text Link Sales, which can be exploited by malicious people to bypass certain security restrictions and by malicious users to conduct SQL injection attacks.

1) The application does not properly restrict access to the "admin.php" script. This can be exploited to gain administrative access to the application by requesting the script directly.

2) input passed to the "id" parameter in admin.php (when "a" is set to "users") is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

NOTE: This can further be exploited to execute arbitrary HTML and script code in a user's browser session via SQL error messages.

Solution:
Restrict access to the admin area (e.g. via ".htaccess").
Edit the source code to ensure that input is properly sanitised.
