The email media type OAuth form passes the Authorization endpoint value to window.open() without validating the URL scheme, so a javascript: URL is executed in the browser. This means a crafted media type configuration, deliverable as an import file, runs arbitrary JavaScript as...
The Perl SNMP trap receiver script shipped with Zabbix does not properly neutralize the ZBXTRAP record delimiter in trap content. This means someone able to send SNMP traps can inject a record targeting another host, resulting in a loss of integrity.
Zabbix Server and Proxy accept the active agent heartbeat message regardless of the configured PSK or certificate authentication. This means someone with access to the Zabbix trapper port can report an arbitrary host using an active agent as available, resulting in a loss of inte...
Host search in Frontend allows filtering by fields that are not displayed, including stored IPMI and PSK credentials. A user with read access can guess a credential and see from the search result whether the guess was right, letting them uncover it.
The Zabbix Server/Proxy has a vulnerability where binary items can crash the Server/Proxy on certain NULL byte input leading to potential loss of availability. This only affects deployments where MySQL/MariaDB database is used as the Zabbix database.
The JavaScript preprocessing (Duktape) engine on Zabbix server has a vulnerability where a limited administrator is able to read raw heap data potentially resulting in leaked data from other running preprocessors not available to said administrator.
When Zabbix Agent was installed on Windows into a custom installation directory, the installer did not verify whether the selected directory had secure access permissions. If the target directory allowed unauthorized users to modify its contents, an attacker could place a malicio...
An authenticated administrator is able to crash Zabbix server or proxy by creating specifically crafted preprocessing/script item JavaScript scripts, leading to potential denial of service.
The Zabbix API host.get action can be exploited by authenticated users to extract a host's PSK key leading to potential loss of data integrity.
A Zabbix administrator is able to read out of bounds memory by utilizing a flaw in script item/preprocessing (JavaScript) HttpRequest logic, leading to potential confidentiality loss.
An authenticated user is able to cause disproportionate CPU load on the Frontend webserver by sending specifically crafted requests to the Frontend validate.api.exists action, leading to potential denial of service.
In Zabbix 7.4 the cryptographic key used for signing Frontend sessions has been erroneously written to the database seed. Currently the only known exploitation scenario is for deployments that utilize both - SAML authentication and guest users. In such cases the key can be used t...
The frontend validatate.api.exists action can be exploited by authenticated users to extract plaintext user macro values leading to potential loss of confidentiality.
An unauthenticated user is able to cause disproportionate CPU load on the Frontend webserver by sending specifically crafted requests to the Frontend popup.testtriggerexpr action, leading to potential denial of service.
Prototype pollution vulnerability in searchParamsToObject() is leading to a persistent XSS in Maps. URL parameter processing was not filtering dangerous properties like proto, combined with jQuery's unsafe element creation that traversed the prototype chain.
Zabbix API and Frontend login lockout mechanism has a flaw where several unsuccessful login requests are not properly counted towards the block counter if sent simultaneously, potentially allowing for more password guesses than intended.
The email media OAuth field 'Client secret' cannot be read after saving, but a Super Admin can leak it by setting a malicious 'Token endpoint'. Changes were made to reset the client secret upon changing the token endpoint.
The Item history widget (in Zabbix 7.0+) or the Plain text widget (in Zabbix 6.0) can execute injected JavaScript when HTML display is enabled. This can allow an attacker to perform unauthorized actions depending on which user opens a dashboard containing these widgets. The malic...
A user able to connect to Agent 2 can inject an Oracle TNS connection string via the 'service' parameter. This can lead to Agent 2 connecting to an attacker-controlled server and leaking Oracle database credentials if they are saved in a named session.
An authenticated (non-super) administrator can create a maintenance period with a JavaScript payload that is executed by any user that opens tooltip for that maintenance period in the Host navigator widget. This can allow the attacker to perform unauthorized actions depending on...
Zabbix Agent 2 Docker plugin does not properly sanitize the 'docker.container_info' parameters when forwarding them to the Docker daemon. An attacker capable of invoking Agent 2 can read arbitrary files from running Docker containers by injecting them via the Docker archive API.
An unauthenticated attacker can exploit the Frontend 'validate' action to blindly instantiate arbitrary PHP classes. The impact depends on environment setup but appears limited at this time.
A low privilege Zabbix user with API access can exploit a blind SQL injection vulnerability in include/classes/api/CApiService.php to execute arbitrary SQL selects via the sortfield parameter. Although query results are not returned directly, an attacker can exfiltrate arbitrary...
Host and event action script input is validated with a regex (set by the administrator), but the validation runs in multiline mode. If ^ and $ anchors are used in user input validation, an injected newline lets authenticated users bypass the check and inject shell commands.
For performance reasons Zabbix Server/Proxy reuses JavaScript (Duktape) contexts (used in script items, JavaScript reprocessing, Webhooks). This can lead to confidentiality loss where a regular (non-super) Zabbix administrator leaks data for hosts they do not have access to. A fi...
