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.

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.

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 occur at this stage if the wd->browser heap pointer is freed by garbage collection.

The researcher is showing that due to the way the SNMP trap log is parsed, an attacker can craft an SNMP trap with additional lines of information and have forged data show in the Zabbix UI. This attack requires SNMP auth to be off and/or the attacker to know the community/auth details. The attack requires an SNMP item to be configured as text on the target host.
