CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability classified as critical has been found in Zabbix up to 2.0.17/2.2.12/3.0.2 (Network Management Software). Affected is some unknown functionality of the file userparameter_mysql.conf of the component Configuration Script. The manipulation of the argument mysql.size with an unknown input leads to a sql injection vulnerability. CWE is classifying the issue as CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

The mysql user parameter configuration script (userparameter_mysql.conf) in the agent in Zabbix before 2.0.18, 2.2.x before 2.2.13, and 3.0.x before 3.0.3, when used with a shell other than bash, allows context-dependent attackers to execute arbitrary code or SQL commands via the mysql.size parameter.

The bug was discovered 05/03/2016. The weakness was disclosed 01/23/2017 by Timo Lindfors as EDB-ID 39769 as confirmed exploit (Exploit-DB). The advisory is shared for download at exploit-db.com. This vulnerability is traded as CVE-2016-4338 since 04/27/2016. It is possible to launch the attack remotely. A authentication is required for exploitation. Technical details and a public exploit are known. The MITRE ATT&CK project declares the attack technique as T1505.

A public exploit has been developed by Timo Lindfors and been published even before and not after the advisory. The exploit is shared for download at exploit-db.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 224 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 95816 (GLSA-201612-42 : Zabbix: Multiple vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Gentoo Local Security Checks and running in the context l.

Upgrading to version 2.0.18 eliminates this vulnerability. A possible mitigation has been published even before and not after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at Exploit-DB (39769), Tenable (95816) and SecurityFocus (BID 89631†). VulDB is the best source for vulnerability data and more expert information about this specific topic.
