 ------------------------------------------------------------------------- Debian LTS Advisory DLA-4131-1 [email protected] https://www.debian.org/lts/security/ Tobias Frost April 19, 2025 https://wiki.debian.org/LTS
 -------------------------------------------------------------------------

 Package : zabbix Version : 1:5.0.46+dfsg-1+deb11u1 CVE ID : CVE-2024-36469 CVE-2024-42325 CVE-2024-45699 CVE-2024-45700 Debian Bug :

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

 CVE-2024-36469

 Execution time for an unsuccessful login differs when using a non-existing username compared to using an existing one.

 CVE-2024-42325

 Zabbix API user.get returns all users that share common group with the calling user. This includes media and other information, such as login attempts, etc.

 CVE-2024-45699

 The endpoint /zabbix.php?action=export.valuemaps suffers from a Cross-Site Scripting vulnerability via the backurl parameter. This is caused by the reflection of user-supplied data without appropriate HTML escaping or output encoding. As a result, a JavaScript payload may be injected into the above endpoint causing it to be executed within the context of the victim's browser.

 CVE-2024-45700

 Zabbix server is vulnerable to a DoS vulnerability due to uncontrolled resource exhaustion. An attacker can send specially crafted requests to the server, which will cause the server to allocate an excessive amount of memory and perform CPU-intensive decompression operations, ultimately leading to a service crash.

 For Debian 11 bullseye, these problems have been fixed in version 1:5.0.46+dfsg-1+deb11u1.

 We recommend that you upgrade your zabbix packages.
