The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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 (CVE-2024-42333)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Fedora 40 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2024-bcdea6e995 advisory.

    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.
