CVESeverityCVSSPublishedSummary
CVE-2024-42327CRITICAL9.9Nov 27, 2024A non-admin user account on the Zabbix frontend with the default User role, or with any other role that gives API access can exploit this vulnerability. An SQLi exists in the CUser class in the addRelatedObjects function, this function is being called from the CUser.get function which is available for every user who has API access.
CVE-2023-32722CRITICAL9.6Oct 12, 2023The zabbix/src/libs/zbxjson module is vulnerable to a buffer overflow when parsing JSON files via zbx_json_open.
CVE-2024-42330CRITICAL9.1Nov 27, 2024The 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.
CVE-2024-36461CRITICAL9.1Aug 12, 2024Within Zabbix, users have the ability to directly modify memory pointers in the JavaScript engine.
CVE-2024-22120CRITICAL9.1May 17, 2024Zabbix server can perform command execution for configured scripts. After command is executed, audit entry is added to "Audit Log". Due to "clientip" field is not sanitized, it is possible to injection SQL into "clientip" and exploit time based blind SQL injection.
CVE-2023-32724CRITICAL9.1Oct 12, 2023Memory pointer is in a property of the Ducktape object. This leads to multiple vulnerabilities related to direct memory access and manipulation.
CVE-2024-36466HIGH8.8Nov 28, 2024A bug in the code allows an attacker to sign a forged zbx_session cookie, which then allows them to sign in with admin permissions.
CVE-2023-29450HIGH8.5Jul 13, 2023JavaScript pre-processing can be used by the attacker to gain access to the file system (read-only access on behalf of user "zabbix") on the Zabbix Server or Zabbix Proxy, potentially leading to unauthorized access to sensitive data.
CVE-2024-36460HIGH8.1Aug 12, 2024The front-end audit log allows viewing of unprotected plaintext passwords, where the passwords are displayed in plain text.
CVE-2023-32721HIGH7.6Oct 12, 2023A 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-2025-27240HIGH7.5Sep 12, 2025A Zabbix adminitrator can inject arbitrary SQL during the autoremoval of hosts by inserting malicious SQL in the 'Visible name' field.
CVE-2024-45699HIGH7.5Apr 2, 2025The endpoint /zabbix.php?action=export.valuemaps suffers from a Cross-Site Scripting vulnerability via the backurl parameter. This is caused by the reflection of user-supplied data without appropriate HTML escaping or output encoding. As a result, a JavaScript payload may be injected into the above endpoint causing it to be executed within the context of the victim's browser.
CVE-2024-36467HIGH7.5Nov 27, 2024An authenticated user with API access (e.g.: user with default User role), more specifically a user with access to the user.update API endpoint is enough to be able to add themselves to any group (e.g.: Zabbix Administrators), except to groups that are disabled or having restricted GUI access.
CVE-2024-36463MEDIUM6.5Nov 26, 2024The implementation of atob in "Zabbix JS" allows to create a string with arbitrary content and use it to access internal properties of objects.
CVE-2024-22121MEDIUM6.1Aug 12, 2024A non-admin user can change or remove important features within the Zabbix Agent application, thus impacting the integrity and availability of the application.
CVE-2023-29458MEDIUM5.9Jul 13, 2023Duktape is an 3rd-party embeddable JavaScript engine, with a focus on portability and compact footprint. When adding too many values in valstack JavaScript will crash. This issue occurs due to bug in Duktape 2.6 which is an 3rd-party solution that we use.
CVE-2023-29449MEDIUM5.9Jul 13, 2023JavaScript preprocessing, webhooks and global scripts can cause uncontrolled CPU, memory, and disk I/O utilization. Preprocessing/webhook/global script configuration and testing are only available to Administrative roles (Admin and Superadmin). Administrative privileges should be typically granted to users who need to perform tasks that require more control over the system. The security risk is limited because not all users have this level of access.
CVE-2024-22119MEDIUM5.5Feb 9, 2024The cause of vulnerability is improper validation of form input field “Name” on Graph page in Items section.
CVE-2023-29452MEDIUM5.5Jul 13, 2023 Currently, geomap configuration (Administration -> General -> Geographical maps) allows using HTML in the field “Attribution text” when selected “Other” Tile provider.
