AlienVault OTX Vulnerabilities

AlienVault OTX Malware

zabbix

An authenticated user in Zabbix can cause disproportionate CPU load, potentially impacting system performance. This vulnerability affects multiple specific Ubuntu package versions of Zabbix. The issue does not involve user interaction or network attack vectors beyond authenticated access. The severity is assessed as medium based on the potential impact on resource consumption.

CVE-2026-23934 describes a vulnerability in Zabbix where an authenticated user can trigger disproportionate CPU load. The vulnerability requires low attack complexity and no user interaction but does require privileges of a logged-in user. It does not affect confidentiality, integrity, or availability directly but may degrade system performance due to excessive CPU usage. The affected versions are specific Ubuntu package builds of Zabbix across multiple LTS releases. No known exploits are reported in the wild, and no patch links are provided in the data.

Zabbix's API and frontend login lockout mechanism has a flaw where multiple simultaneous unsuccessful login attempts are not properly counted towards the lockout threshold. This can potentially allow an attacker to make more password guesses than intended before being blocked. The vulnerability has a medium severity with a CVSS score of 3.7, indicating limited impact primarily on integrity. No specific affected versions or patches are currently provided.

The vulnerability in Zabbix's API and frontend login lockout mechanism involves improper counting of simultaneous unsuccessful login requests towards the block counter. This flaw can allow attackers to bypass the intended lockout restrictions by sending multiple login attempts concurrently, thus increasing the number of password guesses allowed. The CVSS score of 3.7 reflects a network attack vector with high attack complexity, no privileges required, no user interaction, and limited impact on integrity only. There is no indication of confidentiality or availability impact. No known exploits are reported in the wild, and no patch or remediation details are provided in the available data.
