A critical vulnerability identified as CVE-2024-37288 affects Elastic's Kibana component. This vulnerability allows arbitrary code execution due to a deserialization issue when Kibana parses a specially crafted YAML document. The severity of this vulnerability is underscored by its CVSS score of 9.9, indicating a critical risk to organizations utilizing affected versions of Kibana.
Risk to organizations includes potential unauthorized access and control over the Kibana server, especially for users employing Elastic Security's built-in AI tools and those who have configured an Amazon Bedrock connector.
As of now, there are no public exploits confirmed for this vulnerability, but its critical nature necessitates immediate attention. Organizations should prioritize patching to prevent any potential exploitation.
Given the impact and severity of this vulnerability, organizations using Kibana should address it in their priority patch cycle.
Vulnerability Details
CVE-2024-37288 is a deserialization issue in Kibana that can lead to arbitrary code execution when processing a YAML document with a crafted payload. This vulnerability specifically affects users leveraging Elastic Security’s built-in AI tools. The version affected is Kibana 8.15.0 and later.
The CVSS score for this vulnerability is 9.9, indicating a critical severity level. The vulnerability's attack vector is categorized as NETWORK, with a low attack complexity, requiring low privileges, and no user interaction needed. The impacts on confidentiality, integrity, and availability are all rated as high.
Technical Analysis
The root cause of this vulnerability lies in the insecure handling of YAML documents within Kibana. Attackers may exploit this flaw by sending specially crafted documents that the application does not properly validate, leading to arbitrary code execution on the server.
The attack vector is network-based, allowing remote exploitation. The attack complexity is considered low, as the exploitation does not require sophisticated techniques. Privileges required are low, meaning that even users with minimal access can carry out the attack. User interaction is not needed, amplifying the risk.
If successfully exploited, the impacts are grave, leading to high confidentiality, integrity, and availability losses.
Risk & Impact Analysis
The real-world deployment risk associated with this vulnerability is significant, particularly for organizations utilizing Kibana in operational environments. Attackers may leverage this flaw to gain unauthorized access, potentially leading to data breaches or service disruptions.
Organizations should be aware of the potential blast radius if this vulnerability is exploited, as it could compromise the entire Kibana instance and any connected data sources or services.
Given the CVSS score and the critical nature of this vulnerability, organizations must act swiftly. It is crucial to address this vulnerability in the priority patch cycle to mitigate the potential risks.
