CVE-2017-2825
An attacker can set up a Man-in-the-Middle server to alter trapper requests made between an active Zabbix proxy and Server to trigger this vulnerability.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.17%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
In the trapper functionality of Zabbix Server 2.4.x, specifically crafted trapper packets can pass database logic checks, resulting in database writes. An attacker can set up a Man-in-the-Middle server to alter trapper requests made between an active Zabbix proxy and Server to trigger this vulnerability.
