# Exploit Title: Zabbix all version / Multiple Vulnerabilities # Exploit Author: TaurusOmar # Twitter:@TaurusOmar # # Date: Jul 23th, 2021 # CVSS: 3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:L/A:L # Version: Zabbix [1.x, 2.x, 3.x, 4,x 5.x] # Risk: High (9.0) # Vendor Homepage: # Tested on: Arch Linux # Greetz: PwnEc # Software Description: Zabbix is the ultimate enterprise-level software designed for real-time monitoring of millions of metrics collected from tens of thousands of servers, virtual machines and network devices. With encryption support it is possible to secure communications between separate Zabbix components (such as Zabbix server, proxies, agents and command-line utilities) using Transport Layer Security (TLS) protocol v.1.2. Certificate-based and pre-shared key-based encryption is supported. Encryption is optional and configurable for individual components. # 1.)
