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 passwords.
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 to read from it will result in a crash.
There was discovered a use after free bug in browser.c in the es_browser_get_variant function
The reported vulnerability is a stack buffer overflow in the zbx_snmp_cache_handle_engineid function within the Zabbix server/proxy code. This issue occurs when copying data from session->securityEngineID to local_record.engineid without proper bounds checking.
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 with AT commands and small part for log file content will be leaked to UI.
An administrator with restricted permissions can exploit the script execution functionality within the Monitoring Hosts section. The lack of default escaping for script parameters enabled this user ability to execute arbitrary code via the Ping script, thereby compromising infrastructure.
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.
Uncontrolled resource consumption refers to a software vulnerability where a attacker or system uses excessive resources, such as CPU, memory, or network bandwidth, without proper limitations or controls. This can cause a denial-of-service (DoS) attack or degrade the performance of the affected system.
Within Zabbix, users have the ability to directly modify memory pointers in the JavaScript engine.
The front-end audit log allows viewing of unprotected plaintext passwords, where the passwords are displayed in plain text.
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 commands on modem.
A non-admin user can change or remove important features within the Zabbix Agent application, thus impacting the integrity and availability of the application.
Zabbix 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.
The cause of vulnerability is improper validation of form input field “Name” on Graph page in Items section.
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.
Reflected XSS attacks, occur when a malicious script is reflected off a web application to the victim's browser. The script can be activated through Action form fields, which can be sent as request to a website with a vulnerability that enables execution of malicious scripts.
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.
URL validation scheme receives input from a user and then parses it to identify its various components. The validation scheme can ensure that all URL components comply with internet standards.
Stored or persistent cross-site scripting (XSS) is a type of XSS where the attacker first sends the payload to the web application, then the application saves the payload (e.g., in a database or server-side text files), and finally, the application unintentionally executes the payload for every victim visiting its web pages.
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.
