In Apache Ignite versions from 2.6.0 and before 2.17.0, configured Class Serialization Filters are ignored for some Ignite endpoints. This vulnerability allows attackers to exploit the system by manually crafting an Ignite message containing a vulnerable object whose class is present in the Ignite server classpath. If such a message is sent to Ignite server endpoints, the deserialization by the Ignite server may result in the execution of arbitrary code on the Apache Ignite server side.
The severity of this vulnerability is classified as critical, with a CVSS score of 9.5. The high severity indicates a significant risk to organizations, particularly those that rely on Apache Ignite for their application infrastructure. The exploitation status is currently analyzed, but there have been no confirmed public exploits available.
Organizations should prioritize patching immediately. The potential impact includes unauthorized access to sensitive data, integrity compromise, and availability concerns due to service disruption. It is crucial for organizations to assess their exposure and implement mitigation strategies.
Given the critical nature of this vulnerability, timely remediation is essential for maintaining the security posture of affected systems.
Vulnerability Details
The vulnerability is classified under CWE-502, indicating an issue related to deserialization of untrusted data. This classification highlights the specific weakness that allows for the exploitation of the system. The affected product is Apache Ignite, with the vulnerability present in versions ranging from 2.6.0 to before 2.17.0.
The vulnerability was published on February 14, 2025, and has been analyzed for its impact and exploitability. Apache Ignite users should take note of this critical vulnerability and assess their current version against the published details.
Technical Analysis
The root cause of this vulnerability stems from the incorrect handling of Class Serialization Filters in Apache Ignite. Specifically, when certain Ignite endpoints are configured, these filters are ignored, allowing potentially malicious objects to be deserialized by the server. This creates a significant attack vector, as attackers can exploit network access to send crafted messages to the server.
The attack complexity is considered low, as attackers do not require high privileges or user interaction to exploit this vulnerability. The impact on confidentiality, integrity, and availability is rated as high, meaning successful exploitation could lead to severe consequences for an organization.
Risk & Impact Analysis
Risk to organizations includes the potential for arbitrary code execution, which could lead to unauthorized access, data breaches, and service disruptions. The blast radius for this vulnerability is significant, as many organizations rely on Apache Ignite for critical application infrastructure. Organizations that are unaware of their Ignite deployment may face unexpected risks, emphasizing the importance of proactive vulnerability management.
The urgency for organizations to address this vulnerability is high given its critical CVSS score. Organizations should assess their systems for exposure and prioritize remediation as part of their ongoing security efforts.
