Memory Corruption
Templates do not properly consider backticks (`) as Javascript string delimiters, and do not escape them as expected
CVE-2023-29453
9.8 - Critical
- October 12, 2023
Templates do not properly consider backticks (`) as Javascript string delimiters, and do not escape them as expected. Backticks are used, since ES6, for JS template literals. If a template contains a Go template action within a Javascript template literal, the contents of the action can be used to terminate the literal, injecting arbitrary Javascript code into the Go template. As ES6 template literals are rather complex, and themselves can do string interpolation, the decision was made to simply disallow Go template actions from being used inside of them (e.g., "var a = {{.}}"), since there is no obviously safe way to allow this behavior. This takes the same approach as github.com/google/safehtml. With fix, Template. Parse returns an Error when it encounters templates like this, with an ErrorCode of value 12. This ErrorCode is currently unexported but will be exported in the release of Go 1.21. Users who rely on the previous behavior can re-enable it using the GODEBUG flag jstmpllitinterp=1, with the caveat that backticks will now be escaped. This should be used with caution.

CVE-2022-43515
9.8 - Critical
- December 05, 2022
Zabbix Frontend provides a feature that allows admins to maintain the installation and ensure that only certain IP addresses can access it. In this way, any user will not be able to access the Zabbix Frontend while it is being maintained and possible sensitive data will be prevented from being disclosed. An attacker can bypass this protection and access the instance using IP address not listed in the defined range.

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.
XSS
An authenticated user can create a link with reflected Javascript code inside it for graphs page and send it to other users
CVE-2022-24919
4.4 - Medium

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 victims computer, understand attacked infrastructure, be recognized by the victim as a trustee and use trusted communication channel.
XSS
Zabbix 4.0 LTS, 4.2, 4.4, and 5.0 LTS is vulnerable to Remote Code Execution (RCE)
CVE-2021-46088

CVE-2022-23131
9.8 - Critical
- January 13, 2022

CVE-2022-23133
5.4 - Medium
- January 13, 2022
An authenticated user can create a hosts group from the configuration with XSS payload, which will be available for other users.

An issue was discovered in zabbix.php?action=dashboard.view&dashboardid=1 in Zabbix through 4.4. An attacker can bypass the login page and access the dashboard page, and then create a Dashboard, Report, Screen, or Map without any Username/Password (i.e., anonymously). All created elements (Dashboard/Report/Screen/Map) are accessible by other users and by an admin.
Insecure Direct Object Reference / IDOR
Zabbix through 4.4.0alpha1 allows User Enumeration
CVE-2019-15132
5.3 - Medium
- August 17, 2019
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.
Side Channel Attack
