Known Vulnerabilities Affecting Zabbix 5.0 (LTS)

| CVE | Severity | CVSS | Published | Summary |
|---|---|---|---|---|
| CVE-2024-42330 | CRITICAL | 9.1 | Nov 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. |
| CVE-2023-32724 | CRITICAL | 9.1 | Oct 12, 2023 | Memory pointer is in a property of the Ducktape object. This leads to multiple vulnerabilities related to direct memory access and manipulation. |
| CVE-2021-27927 | HIGH | 8.8 | Mar 3, 2021 | 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-2023-32723 | HIGH | 8.5 | Oct 12, 2023 | Request to LDAP is sent before user permissions are checked. |
| CVE-2023-29450 | HIGH | 8.5 | Jul 13, 2023 | JavaScript 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-2024-36460 | HIGH | 8.1 | Aug 12, 2024 | The front-end audit log allows viewing of unprotected plaintext passwords, where the passwords are displayed in plain text. |
| CVE-2023-32721 | HIGH | 7.6 | Oct 12, 2023 | A 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-2024-36467 | HIGH | 7.5 | Nov 27, 2024 | An 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-2021-46088 | HIGH | 7.2 | Jan 27, 2022 | Zabbix 4.0 LTS, 4.2, 4.4, and 5.0 LTS is vulnerable to Remote Code Execution (RCE). Any user with the "Zabbix Admin" role is able to run custom shell script on the application server in the context of the application user. |
| CVE-2024-36463 | MEDIUM | 6.5 | Nov 26, 2024 | The implementation of atob in "Zabbix JS" allows to create a string with arbitrary content and use it to access internal properties of objects. |
| CVE-2022-23133 | MEDIUM | 6.3 | Jan 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. |
| CVE-2024-22121 | MEDIUM | 6.1 | Aug 12, 2024 | A non-admin user can change or remove important features within the Zabbix Agent application, thus impacting the integrity and availability of the application. |
| CVE-2020-15803 | MEDIUM | 6.1 | Jul 17, 2020 | 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-2023-29458 | MEDIUM | 5.9 | Jul 13, 2023 | Duktape 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-2023-29449 | MEDIUM | 5.9 | Jul 13, 2023 | JavaScript 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-2024-22119 | MEDIUM | 5.5 | Feb 9, 2024 | The cause of vulnerability is improper validation of form input field “Name” on Graph page in Items section. |
| CVE-2019-15132 | MEDIUM | 5.3 | Aug 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. |
| CVE-2023-29451 | MEDIUM | 4.7 | Jul 13, 2023 | Specially crafted string can cause a buffer overrun in the JSON parser library leading to a crash of the Zabbix Server or a Zabbix Proxy. |
| CVE-2024-22114 | MEDIUM | 4.3 | Aug 12, 2024 | User with no permission to any of the Hosts can access and view host count & other statistics through System Information Widget in Global View Dashboard. |
| CVE-2022-35230 | LOW | 3.7 | Jul 6, 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. |
