Recent Zabbix Frontend Security Vulnerabilities
HttpRequest Header Encoding Flaw Enables Prototype Pollution in Edge JS
CVE-2024-42330
9.1 - Critical
- November 27, 2024
The HttpRequest object allows to get the HTTP headers from the server's response after sending the request. The problem is that the returned strings are created directly from the data returned by the server and are not correctly encoded for JavaScript. This allows to create internal strings that can be used to access hidden properties of objects.
Use of Externally-Controlled Format String

CVE-2023-32725
8.8 - High
- December 18, 2023
The website configured in the URL widget will receive a session cookie when testing or executing scheduled reports. The received session cookie can then be used to access the frontend as the particular user.
Reliance on Cookies without Validation and Integrity Checking

CVE-2023-30958
6.1 - Medium
- August 03, 2023
A security defect was identified in Foundry Frontend that enabled users to potentially conduct DOM XSS attacks if Foundry's CSP were to be bypassed. This defect was resolved with the release of Foundry Frontend 6.225.0.
XSS
Reflected XSS via action form field in web app (CVE-2023-29457)
CVE-2023-29457
6.3 - Medium
- July 13, 2023
Reflected XSS attacks, occur when a malicious script is reflected off a web application to the victim's browser. The script can be activated through Action form fields, which can be sent as request to a website with a vulnerability that enables execution of malicious scripts.
Improper Input Validation
Reflected XSS via URL in unknown web app
CVE-2023-29455
5.4 - Medium
- July 13, 2023
Reflected XSS attacks, also known as non-persistent attacks, occur when a malicious script is reflected off a web application to the victim's browser. The script is activated through a link, which sends a request to a website with a vulnerability that enables execution of malicious scripts.
Improper Input Validation
CVE-2023-29454: Stored XSS in Unknown Web Application
CVE-2023-29454
5.4 - Medium
- July 13, 2023
Stored or persistent cross-site scripting (XSS) is a type of XSS where the attacker first sends the payload to the web application, then the application saves the payload (e.g., in a database or server-side text files), and finally, the application unintentionally executes the payload for every victim visiting its web pages.
Improper Input Validation
URL Validation Scheme Vulnerability: Untrusted Input Parsing
CVE-2023-29456
5.7 - Medium
- July 13, 2023
URL validation scheme receives input from a user and then parses it to identify its various components. The validation scheme can ensure that all URL components comply with internet standards.
Improper Input Validation
Zabbix Frontend IP Bypass in Admin Maintenance Mode
CVE-2022-43515
5.3 - Medium
- 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.
Improper Input Validation
An authenticated user can create a link with reflected Javascript code inside it for the graphs page and send it to other users
CVE-2022-35230
3.7 - Low
- July 06, 2022
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.
XSS
An authenticated user can create a link with reflected Javascript code inside it for the discovery page and send it to other users
CVE-2022-35229
3.7 - Low
- July 06, 2022
An authenticated user can create a link with reflected Javascript code inside it for the discovery 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.
XSS
An authenticated user can create a link with reflected XSS payload for actions pages, and send it to other users
CVE-2022-24349
4.6 - Medium
- March 09, 2022
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
An authenticated user can create a link with reflected Javascript code inside it for services page and send it to other users
CVE-2022-24917
3.7 - Low
- March 09, 2022
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.
XSS
An authenticated user can create a link with reflected Javascript code inside it for items page and send it to other users
CVE-2022-24918
3.7 - Low
- March 09, 2022
An authenticated user can create a link with reflected Javascript code inside it for items 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.
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
3.7 - Low
- March 09, 2022
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.
XSS
In the case of instances where the SAML SSO authentication is enabled (non-default), session data can be modified by a malicious actor
CVE-2022-23131
9.1 - Critical
- January 13, 2022
In the case of instances where the SAML SSO authentication is enabled (non-default), session data can be modified by a malicious actor, because a user login stored in the session was not verified. Malicious unauthenticated actor may exploit this issue to escalate privileges and gain admin access to Zabbix Frontend. To perform the attack, SAML authentication is required to be enabled and the actor has to know the username of Zabbix user (or use the guest account, which is disabled by default).
Authentication Bypass by Spoofing
After the initial setup process
CVE-2022-23134
3.7 - Low
- January 13, 2022
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.

An authenticated user can create a hosts group from the configuration with XSS payload, which will be available for other users
CVE-2022-23133
6.3 - 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. When XSS is stored by an authenticated malicious actor and other users try to search for groups during new host creation, the XSS payload will fire and the actor can steal session cookies and perform session hijacking to impersonate users or take over their accounts.
