Support Incident Tracker (SiT!) 3.63 p1 - 'search.php?search_string' SQL Injection

source: https://www.securityfocus.com/bid/48896/info
  
Support Incident Tracker is prone to multiple SQL-injection vulnerabilities because the application fails to properly sanitize user-supplied input before using it in an SQL query.
  
A successful exploit could allow an attacker to compromise the application, access or modify data, or exploit vulnerabilities in the underlying database.
  
Support Incident Tracker 3.63p1 is vulnerable; other versions may also be affected.
