tomplixsee has discovered some vulnerabilities in aliTalk, which can be exploited by malicious people to conduct SQL injection attacks.

1) Input passed to the "mohit" parameter in inc/receivertwo.php is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

2) Input passed to the "id" parameter in inc/usercp.php is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

Successful exploitation of this vulnerability allows e.g. changing passwords for arbitrary users.

3) Input passed to the "username" parameter in admin/index.php is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

Successful exploitation of this vulnerability allows e.g. logging in as administrator without valid administrator credentials, but requires knowledge of the administrator username.

4) Input passed to the "username" parameter in index.php is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

Successful exploitation of all vulnerabilities also require that "magic_quotes_gpc" is disabled.

The vulnerabilities are confirmed in version 1.9.1.1. Other versions may also be affected.
