According to its self-reported version number, the instance of Zabbix running on the remote host is 2.0.x prior to 2.0.21, 2.2.x prior to 2.2.18, 3.0.x prior to 3.0.9, or 3.2.x prior to 3.2.5. It is, therefore, affected by multiple vulnerabilities :
A remote code execution vulnerability exists in the trapper command functionality due to improper handling of trapper packets. An unauthenticated, remote attacker can exploit this, via a specially crafted set of trapper packets, to inject arbitrary commands and execute arbitrary code. (CVE-2017-2824 / TALOS-2017-0325)
A security bypass vulnerability exists in the trapper command functionality due to improper handling of trapper packets. A man-in-the-middle (MitM) attacker can exploit this, via a specially crafted trapper packet, to bypass database security checks and write arbitrary data to the database. (CVE-2017-2825 / TALOS-2017-0326)
Note that Nessus has not tested for these issues but has instead relied only on the applicationβs self-reported version number.
