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.
