------------------------------------------------------------------------- Debian LTS Advisory DLA-3984-1 [email protected] https://www.debian.org/lts/security/ Tobias Frost December 07, 2024 https://wiki.debian.org/LTS
-------------------------------------------------------------------------

Package : zabbix Version : 1:5.0.45+dfsg-1+deb11u1 CVE ID : CVE-2024-36464 CVE-2024-42330 CVE-2024-42331 CVE-2024-42332 CVE-2024-42333 Debian Bug : 1088689

Several security vulnerabilities have been discovered in zabbix, a network monitoring solution, potentially among other effects allowing denial of service, information disclosure, use-after-free or remote code inclusion.

CVE-2024-36464

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.

CVE-2024-42330

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.

CVE-2024-42331

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.

CVE-2024-42332

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.

CVE-2024-42333

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

For Debian 11 bullseye, these problems have been fixed in version 1:5.0.45+dfsg-1+deb11u1.

We recommend that you upgrade your zabbix packages.
