Some vulnerabilities have been discovered in the ZABBIX PHP frontend, which can be exploited by malicious people to conduct SQL injection attacks.
1) Input passed via the "user" JSON parameter to api_jsonrpc.php is not properly sanitised before being used in a SQL query in include/db.inc.php script. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
2) Input passed via the "nav_time" parameter to events.php is not properly sanitised before being used in an SQL query in api/classes/cevents.php script. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
The vulnerabilities are confirmed in version 1.8.1. Prior versions may also be affected.
