"The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 ESM host has packages installed that are affected by multiple
vulnerabilities as referenced in the USN-4767-1 advisory.

  - XML external entity (XXE) vulnerability in Zabbix 1.8.x before 1.8.21rc1, 2.0.x before 2.0.13rc1, 2.2.x
    before 2.2.5rc1, and 2.3.x before 2.3.2 allows remote attackers to read arbitrary files or potentially
    execute arbitrary code via a crafted DTD in an XML request. (CVE-2014-3005)

  - SQL injection vulnerability in Zabbix before 2.2.14 and 3.0 before 3.0.4 allows remote attackers to
    execute arbitrary SQL commands via the toggle_ids array parameter in latest.php. (CVE-2016-10134)

  - Zabbix before 2.2.21rc1, 3.x before 3.0.13rc1, 3.1.x and 3.2.x before 3.2.10rc1, and 3.3.x and 3.4.x
    before 3.4.4rc1 allows open redirect via the request parameter. (CVE-2016-10742)

  - The mysql user parameter configuration script (userparameter_mysql.conf) in the agent in Zabbix before
    2.0.18, 2.2.x before 2.2.13, and 3.0.x before 3.0.3, when used with a shell other than bash, allows
    context-dependent attackers to execute arbitrary code or SQL commands via the mysql.size parameter.
    (CVE-2016-4338)

  - An exploitable code execution vulnerability exists in the trapper command functionality of Zabbix Server
    2.4.X. A specially crafted set of packets can cause a command injection resulting in remote code
    execution. An attacker can make requests from an active Zabbix Proxy to trigger this vulnerability.
    (CVE-2017-2824)

  - In the trapper functionality of Zabbix Server 2.4.x, specifically crafted trapper packets can pass
    database logic checks, resulting in database writes. An attacker can set up a Man-in-the-Middle server to
    alter trapper requests made between an active Zabbix proxy and Server to trigger this vulnerability.
    (CVE-2017-2825)

  - Zabbix through 4.4.0alpha1 allows User Enumeration. With login requests, it is possible to enumerate
    application usernames based on the variability of server responses (e.g., the Login name or password is
    incorrect and No permissions for system access messages, or just blocking for a number of seconds).
    This affects both api_jsonrpc.php and index.php. (CVE-2019-15132)

  - Zabbix Server 2.2.x and 3.0.x before 3.0.31, and 3.2 allows remote attackers to execute arbitrary code.
    (CVE-2020-11800)

  - 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)

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