CVE-2023-32727 is a security vulnerability in Zabbix server that was disclosed on December 18, 2023. The vulnerability affects multiple versions of Zabbix server including versions 4.0.0-4.0.49, 5.0.0-5.0.38, 6.0.0-6.0.22, 6.4.0-6.4.7, and early alpha versions of 7.0.0. This vulnerability allows an attacker with privileges to configure Zabbix items to execute arbitrary code on the Zabbix server through the icmpping() function (Zabbix Advisory).

The vulnerability is classified as CWE-20 (Improper Input Validation) and has received a CVSS v3.1 base score of 7.2 (High) from NIST with a vector string of CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H. Zabbix assigned a slightly lower CVSS score of 6.8 (Medium) with a vector string of CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:H/I:H/A:H. The vulnerability specifically involves the icmpping() function, which can be manipulated to include malicious commands (NVD).

If exploited, this vulnerability allows attackers to execute arbitrary code on the affected Zabbix server, potentially leading to complete system compromise. The impact is particularly severe as it affects confidentiality, integrity, and availability of the system, all rated as High in the CVSS scoring (NVD).

Fixed versions have been released for all affected versions: 4.0.50 for 4.0.x, 5.0.39 for 5.0.x, 6.0.23rc1 for 6.0.x, 6.4.8rc1 for 6.4.x, and 7.0.0alpha7 for the 7.0 alpha series. Users are advised to upgrade to these patched versions to mitigate the vulnerability (Zabbix Advisory).
