Zabbix

A critical cross-site scripting (XSS) vulnerability has been identified in Zabbix, which a remote, unauthenticated attacker can exploit to execute malicious scripts within a user's browser session, potentially leading to unauthorized actions or data theft.

This brief describes how attackers exploit vulnerabilities in web applications to execute suspicious shell commands via web server processes on Linux, enabling persistence, discovery, credential access, and reverse shell establishment, which can lead to full system compromise and data exfiltration.

Identifies suspicious command executions via a web server on Linux systems, potentially indicating a vulnerability exploitation or remote shell access for persistence.

Multiple vulnerabilities in Zabbix versions 6.0.x before 6.0.45, 7.0.x before 7.0.24, and 7.4.x before 7.4.8 allow for data confidentiality breaches and remote cross-site scripting (XSS) attacks.
