CVE-2024-22116 is a critical vulnerability affecting Zabbix, a widely used open-source monitoring tool. This vulnerability allows an administrator with restricted permissions to exploit the script execution functionality within the Monitoring Hosts section. The lack of default escaping for script parameters enables this user ability to execute arbitrary code via the Ping script, thereby compromising infrastructure. With a CVSS score of 9.9, organizations should prioritize patching immediately.
The security implications of this vulnerability are severe. Attackers may leverage this flaw to gain unauthorized access to sensitive systems, leading to potential data breaches or service disruptions. The urgency for defenders is underscored by the vulnerability's critical nature and the ease with which it can be exploited.
Organizations utilizing affected versions of Zabbix, specifically versions 6.4.9 to 6.4.15 and various alpha, beta, and release candidate versions of 7.0.0, must act swiftly to remediate this vulnerability. Without prompt action, the risk to organizational infrastructure increases significantly.
As this vulnerability is known to the public, security practitioners need to remain vigilant and ensure that their systems are patched against this threat to maintain the integrity and availability of their services.
Vulnerability Details
The official description of CVE-2024-22116 states that an administrator with restricted permissions can exploit the script execution functionality within the Monitoring Hosts section. The lack of default escaping for script parameters enables this user to execute arbitrary code via the Ping script, thereby compromising infrastructure.
This vulnerability falls under the CWE-94 classification, which pertains to improper control of generation of code ('code injection'). With a CVSS score of 9.9, it is categorized as critical due to potential high impact on confidentiality, integrity, and availability.
The affected vendor is Zabbix, impacting the Zabbix product across specified versions. The vulnerability was published on August 12, 2024.
Technical Analysis
The root cause of CVE-2024-22116 lies in the inadequate escaping of script parameters within the Zabbix Monitoring Hosts feature. This oversight allows an attacker with low privileges to execute arbitrary code.
The attack vector is network-based (AV:N), with a low attack complexity (AC:L). Only low privileges (PR:L) are required to exploit this vulnerability, and no user interaction (UI:N) is necessary. The scope of the vulnerability changes (S:C), indicating that the exploitation impacts other components within the system.
The impacts are significant, affecting confidentiality (C:H), integrity (I:H), and availability (A:H), emphasizing the critical nature of this vulnerability.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2024-22116 is substantial. Organizations utilizing vulnerable Zabbix versions could face unauthorized access and exploitation of critical systems.
The potential blast radius encompasses all infrastructure monitored by the compromised Zabbix instance, posing a significant threat to data integrity and service availability. Given the critical CVSS score, organizations should address this vulnerability in their priority patch cycle.
The urgency assessment is critical, demanding immediate remediation efforts to mitigate exposure and prevent potential exploitation.
