The remote SUSE Linux SUSE15 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2022:0036-1 advisory.

  • Zabbix before 3.0.32rc1, 4.x before 4.0.22rc1, 4.1.x through 4.4.x before 4.4.10rc1, and 5.x before 5.0.2rc1 allows stored XSS in the URL Widget. (CVE-2020-15803)

  • In Zabbix from 4.0.x before 4.0.28rc1, 5.0.0alpha1 before 5.0.10rc1, 5.2.x before 5.2.6rc1, and 5.4.0alpha1 before 5.4.0beta2, the CControllerAuthenticationUpdate controller lacks a CSRF protection mechanism. The code inside this controller calls diableSIDValidation inside the init() method. An attacker doesn’t have to know Zabbix user login credentials, but has to know the correct Zabbix URL and contact information of an existing user with sufficient privileges. (CVE-2021-27927)

  • After the initial setup process, some steps of setup.php file are reachable not only by super- administrators, but by unauthenticated users as well. Malicious actor can pass step checks and potentially change the configuration of Zabbix Frontend. (CVE-2022-23134)

Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
