In the src/libs/zbxembed/browser.c file, the es_browser_ctor method retrieves a heap pointer from the Duktape JavaScript engine. This heap pointer is subsequently utilized by the browser_push_error method in the src/libs/zbxembed/browser_error.c file. A use-after-free bug can…

The webdriver for the Browser object expects an error object to be initialized when the webdriver_session_query function fails. But this function can fail for various reasons without an error description and then the wd->error will be NULL and trying to read from it will result…

When the webdriver for the Browser object downloads data from a HTTP server, the data pointer is set to NULL and is allocated only in curl_write_cb when receiving data. If the server's response is an empty document, then wd->data in the code below will remain NULL and an attempt…

Execution time for an unsuccessful login differs when using a non-existing username compared to using an existing one.

Zabbix allows to configure SMS notifications. AT command injection occurs on "Zabbix Server" because there is no validation of "Number" field on Web nor on Zabbix server side. Attacker can run test of SMS providing specially crafted phone number and execute additional AT…

When exporting media types, the password is exported in the YAML in plain text. This appears to be a best practices type issue and may have no actual impact. The user would need to have permissions to access the media types and therefore would be expected to have access to these…

The researcher is showing that it is possible to leak a small amount of Zabbix Server memory using an out of bounds read in src/libs/zbxmedia/email.c

Setting SMS media allows to set GSM modem file. Later this file is used as Linux device. But due everything is a file for Linux, it is possible to set another file, e.g. log file and zabbix_server will try to communicate with it as modem. As a result, log file will be broken…

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.

When a URL is added to the map element, it is recorded in the database with sequential IDs. Upon adding a new URL, the system retrieves the last sysmapelementurlid value and increments it by one. However, an issue arises when a user manually changes the sysmapelementurlid value…

zabbix_agentd 1.1.4 in ZABBIX before 1.4.3 runs "UserParameter" scripts with gid 0, which might allow local users to gain privileges.

Multiple SQL injection vulnerabilities in chart_bar.php in the frontend in Zabbix before 1.8.22, 2.0.x before 2.0.14, and 2.2.x before 2.2.8 allow remote attackers to execute arbitrary SQL commands via the (1) itemid or (2) periods parameter.

The Frontend in Zabbix before 1.8.20rc2, 2.0.x before 2.0.11rc2, and 2.2.x before 2.2.2rc1 allows remote "Zabbix Admin" users to modify the media of arbitrary users via unspecified vectors.

libs/zbxmedia/eztexting.c in Zabbix 1.8.x before 1.8.18rc1, 2.0.x before 2.0.8rc1, and 2.1.x before 2.1.2 does not properly set the CURLOPT_SSL_VERIFYHOST option for libcurl, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.

Zabbix before 1.8.19rc1, 2.0 before 2.0.10rc1, and 2.2 before 2.2.1rc1 allows remote Zabbix servers and proxies to execute arbitrary commands via a newline in a flexible user parameter.
