Fortinet Discovers Zabbix Cross-Site Scripting Vulnerability
Fortinet's FortiGuard Labs discovered a cross-site scripting (XSS) vulnerability in Zabbix. The vulnerability exists because Zabbix fails to validate the data from users. It allows remote attackers to inject malicious script/HTML code.
Zabbix is an open source enterprise monitoring software for networks and applications, created in Latvia by Alexei Vladishev. It is designed to monitor and track the status of various network services, servers, and other network hardware.
The XSS vulnerability exists due to insufficiently sanitizing user-supplied data in HTTP request sent to actionconf.php so that remote attackers can exploit it to launch a reflected XSS attack by enticing target users to visit a malicious URL.
