Description
In Apache Ignite versions from 2.6.0 and before 2.17.0, configured Class Serialization Filters are ignored for some Ignite endpoints. The vulnerability could be exploited if an attacker manually crafts an Ignite message containing a vulnerable object whose class is present in the Ignite server classpath and sends it to Ignite server endpoints. Deserialization of such a message by the Ignite server may result in the execution of arbitrary code on the Apache Ignite server side.

Comprehensive Technical Analysis of EUVD-2025-4892
1. Vulnerability Assessment and Severity Evaluation
The vulnerability described in EUVD-2025-4892 affects Apache Ignite versions from 2.6.0 to 2.17.0. The issue arises from the improper handling of Class Serialization Filters, which can be bypassed for certain Ignite endpoints. This allows an attacker to send a crafted message containing a vulnerable object, leading to arbitrary code execution on the server side upon deserialization.
Severity Evaluation:
- Base Score: 9.5 (Critical)
- Base Score Vector: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H
The high base score indicates a critical vulnerability due to the potential for remote code execution (RCE) without requiring user interaction or privileges. The attack complexity is low, and the impact on confidentiality, integrity, and availability is high.
2. Potential Attack Vectors and Exploitation Methods
Attack Vectors:
- Network-Based Attack: An attacker can exploit this vulnerability over the network by sending a specially crafted message to the Ignite server.
- Man-in-the-Middle (MitM): If an attacker can intercept and modify network traffic, they could inject malicious serialized objects.
Exploitation Methods:
- Crafted Message: The attacker crafts an Ignite message containing a serialized object that, when deserialized, executes arbitrary code.
- Classpath Manipulation: The attacker ensures that the vulnerable class is present in the Ignite server's classpath to facilitate the exploitation.
3. Affected Systems and Software Versions
Affected Software:
- Apache Ignite versions from 2.6.0 to 2.17.0
Affected Systems:
- Any system running the affected versions of Apache Ignite, including but not limited to:
- Enterprise data grids
- Distributed caching systems
- In-memory computing platforms
4. Recommended Mitigation Strategies
Immediate Mitigation:
- Upgrade: Upgrade to Apache Ignite version 2.17.0 or later, which includes the fix for this vulnerability.
- Patch Management: Ensure that all systems running Apache Ignite are regularly updated and patched.
Additional Mitigation:
- Network Segmentation: Isolate Ignite servers from untrusted networks to reduce the attack surface.
- Firewall Rules: Implement strict firewall rules to limit access to Ignite endpoints.
- Input Validation: Enhance input validation and sanitization for all incoming messages.
- Monitoring and Logging: Implement robust monitoring and logging to detect and respond to suspicious activities.
5. Impact on European Cybersecurity Landscape
The vulnerability poses a significant risk to organizations using Apache Ignite within the European Union. Given the critical nature of the vulnerability, it could lead to:
- Data Breaches: Unauthorized access to sensitive data.
- Service Disruptions: Compromised systems leading to downtime and service interruptions.
- Compliance Issues: Potential violations of GDPR and other regulatory requirements due to data breaches.
Sector-Specific Impact:
- Financial Services: High risk due to the use of in-memory computing for real-time data processing.
- Healthcare: Potential exposure of sensitive patient data.
- Telecommunications: Risk of service disruptions and data breaches.
6. Technical Details for Security Professionals
Vulnerability Details:
- Root Cause: Improper handling of Class Serialization Filters, allowing bypass for certain endpoints.
- Exploitation: Deserialization of a crafted message leads to arbitrary code execution.
Detection and Response:
- Intrusion Detection Systems (IDS): Configure IDS to detect unusual network traffic patterns indicative of exploitation attempts.
- Incident Response: Develop and test incident response plans specific to deserialization vulnerabilities.
- Code Review: Conduct thorough code reviews to identify and mitigate similar vulnerabilities in other parts of the system.
References:
Conclusion: The vulnerability in Apache Ignite versions from 2.6.0 to 2.17.0 is critical and requires immediate attention. Organizations should prioritize upgrading to the patched version and implement additional security measures to mitigate the risk.
