The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3717 advisory.

  • A stored XSS has been found in the Zabbix web application in the Maps element if a URL field is set with spaces before URL. (CVE-2023-32721)

  • Request to LDAP is sent before user permissions are checked. (CVE-2023-32723)

  • The vulnerability is caused by improper check for check if RDLENGTH does not overflow the buffer in response from DNS server. (CVE-2023-32726)

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