This update for zabbix fixes the following issues :

Updated to version 3.0.31.

  + CVE-2020-15803: Fixed an XSS in the URL Widget     (boo#1174253).

Multiple vulnerabilities were discovered in Zabbix, a network monitoring solution. An attacker may enumerate valid users and redirect to external links through the zabbix web frontend.

CVE-2019-15132

Zabbix 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-2020-15803

Zabbix allows stored XSS in the URL Widget. This fix was mistakenly dropped in previous upload 1:3.0.31+dfsg-0+deb9u1.

This update also includes several other bug fixes and improvements.
For more information please refer to the upstream changelog file.

For Debian 9 stretch, these problems have been fixed in version 1:3.0.32+dfsg-0+deb9u1.

We recommend that you upgrade your zabbix packages.

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.

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3390 advisory.

  - 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 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)

  - An authenticated user can create a link with reflected XSS payload for actions' pages, and send it to     other users. Malicious code has access to all the same objects as the rest of the web page and can make     arbitrary modifications to the contents of the page being displayed to a victim. This attack can be     implemented with the help of social engineering and expiration of a number of factors - an attacker should     have authorized access to the Zabbix Frontend and allowed network connection between a malicious server     and victim's computer, understand attacked infrastructure, be recognized by the victim as a trustee and     use trusted communication channel. (CVE-2022-24349)

  - An authenticated user can create a link with reflected Javascript code inside it for services' page and     send it to other users. The payload can be executed only with a known CSRF token value of the victim,     which is changed periodically and is difficult to predict. Malicious code has access to all the same     objects as the rest of the web page and can make arbitrary modifications to the contents of the page being     displayed to a victim during social engineering attacks. (CVE-2022-24917)

  - An authenticated user can create a link with reflected Javascript code inside it for graphs' page and send     it to other users. The payload can be executed only with a known CSRF token value of the victim, which is     changed periodically and is difficult to predict. Malicious code has access to all the same objects as the     rest of the web page and can make arbitrary modifications to the contents of the page being displayed to a     victim during social engineering attacks. (CVE-2022-24919)

  - An authenticated user can create a link with reflected Javascript code inside it for the graphs page and     send it to other users. The payload can be executed only with a known CSRF token value of the victim,     which is changed periodically and is difficult to predict. (CVE-2022-35230)

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)
