CVSS v3.1 |
| 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. |
| 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 malicious DLL that could later be loaded by the application, resulting in DLL sideloading. The installer has been hardened to detect potentially unsafe installation directories and now requires explicit user confirmation before proceeding with installation in such locations. This reduces the risk of accidental installation into directories with inappropriate permissions while preserving compatibility with existing deployment scenarios. |
| 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 to forge valid session cookies, potentially leading to unauthorized access. For other Zabbix deployments this does not have a known impact. |
| 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. |
| An authenticated Zabbix user (User role) with template/host write permissions is able to create objects via the configuration.import API. This can lead to confidentiality loss by creating unauthorized hosts. Note that the User role is normally not sufficient to create and edit templates/hosts even with write permissions. |
| 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. |
| 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 malicious JavaScript would have to come from a monitored host controlled by the attacker. Note: the Item history widget is a replacement for the Plain text widget since Zabbix 7.0. |
| 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 which user opens the tooltip. |
| SQL injection vulnerability in the get_history_lastid function in the nodewatcher component in Zabbix Server before 1.6.8 allows remote attackers to execute arbitrary SQL commands via a crafted request, possibly related to the send_history_last_id function in zabbix_server/trapper/nodehistory.c. |
| Buffer overflow in ZABBIX before 1.1.5 has unknown impact and attack vectors related to "SNMP IP addresses." |
| The node_process_command function in Zabbix Server before 1.8 allows remote attackers to execute arbitrary commands via a crafted request. |
| zabbix_agentd in ZABBIX 1.4.4 allows remote attackers to cause a denial of service (CPU and connection consumption) via multiple vfs.file.cksum commands with a special device node such as /dev/urandom or /dev/zero. |
| The NET_TCP_LISTEN function in net.c in Zabbix Agent before 1.6.7, when running on FreeBSD or Solaris, allows remote attackers to bypass the EnableRemoteCommands setting and execute arbitrary commands via shell metacharacters in the argument to net.tcp.listen. NOTE: this attack is limited to attacks from trusted IP addresses. |
