The ObjectSerializationDecoder in Apache MINA utilizes Java's native deserialization protocol to process incoming serialized data but lacks the necessary security checks and defenses. This vulnerability allows attackers to exploit the deserialization process by sending specially crafted malicious serialized data, potentially leading to remote code execution (RCE) attacks. Organizations using affected versions of MINA must take immediate action.
With a CVSS score of 10, this vulnerability is classified as critical. The severity is particularly concerning as it indicates the potential for significant impact to confidentiality, integrity, and availability. The risk to organizations includes unauthorized access and control over affected systems, making the urgency for defenders to address this vulnerability immediately.
Despite the lack of known exploits at this time, the critical nature of the vulnerability necessitates that organizations prioritize patching. The vulnerability affects MINA core versions 2.0.X, 2.1.X, and 2.2.X, with fixes planned in the releases 2.0.27, 2.1.10, and 2.2.4.
To mitigate risks, organizations must not only upgrade to the latest version of the MINA core library but also implement specific security measures to ensure that only approved classes are accepted by the ObjectSerializationDecoder.
Vulnerability Details
The ObjectSerializationDecoder's inherent vulnerabilities stem from its reliance on Java’s deserialization protocol without sufficient security checks. Attackers can exploit this lack of validation to execute arbitrary code remotely, posing a severe risk to applications that utilize this library.
The affected product, Apache MINA, is widely used in various applications, and organizations must remain vigilant about the components they utilize. The vulnerability was published on December 25, 2024, and is classified under CWE-502.
Technical Analysis
The root cause of this vulnerability is the failure to validate incoming serialized data adequately. Attackers may leverage this weakness through a network attack vector with low complexity, requiring no privileges or user interaction. The confidentiality, integrity, and availability impacts are all rated high, indicating that exploitation could lead to severe consequences.
Risk & Impact Analysis
The real-world deployment risk associated with this vulnerability is substantial. Organizations using vulnerable versions of Apache MINA face the threat of remote code execution, which could lead to unauthorized access to sensitive data and system control. Given the potential blast radius, organizations must prioritize remediation based on the CVSS score indicating critical severity.

Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The vulnerability affects MINA core versions 2.0.X, 2.1.X, and 2.2.X. Organizations should upgrade to versions 2.0.27, 2.1.10, and 2.2.4 to mitigate this vulnerability. If version information is missing: 'All versions prior to vendor patch.'
Mitigation & Remediation
To mitigate this vulnerability, organizations must not only upgrade to the latest version of the Apache MINA core library but also explicitly allow the classes that the decoder will accept in the ObjectSerializationDecoder instance. This can be done using methods such as accept(ClassNameMatcher), accept(Pattern), or accept(String... patterns). For more detailed guidance, organizations can refer to our application security assessment resources.
Detection Guidance
Organizations should monitor for log indicators that may signify attempts to exploit this vulnerability, such as unusual serialized data patterns. Behavioral anomalies in the application that utilizes the MINA framework should also be logged and analyzed to detect potential exploitation attempts.
AppSecure Threat Intelligence Insight
