This flaw could potentially lead to unauthorized access to hidden properties of objects, putting sensitive data at risk.
The exploitation status for this vulnerability is currently unknown, with no public exploits confirmed. However, given its critical nature, organizations should prioritize patching immediately. The risk to organizations includes potential unauthorized access and data exposure, making timely remediation essential.
This vulnerability highlights the importance of secure coding practices, particularly in encoding user inputs and outputs. As the cyber threat landscape evolves, vulnerabilities like CVE-2024-42330 demonstrate the need for continuous monitoring and proactive security measures.
Organizations using Zabbix must remain vigilant and ensure they are utilizing the latest version to mitigate this risk effectively. The urgency for defenders cannot be overstated, as the potential impact on confidentiality, integrity, and availability is significant.
In summary, CVE-2024-42330 represents a critical risk for Zabbix users. Organizations should act swiftly to address this vulnerability and enhance their overall security posture.
Vulnerability Details
The HttpRequest object allows to get the HTTP headers from the server's response after sending the request. The problem is that the returned strings are created directly from the data returned by the server and are not correctly encoded for JavaScript. This allows to create internal strings that can be used to access hidden properties of objects.
This vulnerability has a CVSS score of 9.1, classified as critical due to its potential impact on confidentiality, integrity, and availability. It affects all versions of Zabbix prior to the vendor patch, specifically those between versions 5.0.0 to 5.4.6, 6.0.0 to 6.0.34, 6.4.0 to 6.4.19, and 7.0.0 to 7.0.4.
Technical Analysis
The root cause of CVE-2024-42330 lies in the improper handling of HTTP headers by the HttpRequest object. The vulnerability is categorized under CWE-134, indicating improper encoding. The attack vector is network-based, meaning an attacker can exploit this vulnerability remotely without requiring local access.
The attack complexity is low, with high privileges required to exploit this vulnerability. No user interaction is necessary, allowing attackers to execute their attack without any action from the victim. The impact on confidentiality, integrity, and availability is categorized as high, emphasizing the serious risks involved.
Risk & Impact Analysis
Organizations using Zabbix face significant risks due to CVE-2024-42330. The potential for unauthorized access can lead to data breaches and exploitation of sensitive information. The blast radius of this vulnerability is extensive, affecting any instance of Zabbix in use.
Given the critical severity of this vulnerability and its potential to be exploited, organizations should assess their exposure and prioritize remediation efforts. The urgency is underscored by the potential for attackers to leverage this vulnerability to gain unauthorized access to sensitive systems.
