How To Fix CVE-2024-52046 - A Critical RCE Vulnerability in Apache MINA Object Serialization Decoder
Apache MINA, a widely used network application framework for building high-performance and scalable network applications, has recently been found to have a critical remote code execution (RCE) vulnerability. Tracked as CVE-2024-52046 and carrying a maximum CVSS score of 10.0, this vulnerability poses a significant risk to organizations using vulnerable versions of the Apache MINA library. Security professionals, DevSecOps teams, and application security experts must take immediate action to protect their systems from potential exploitation.
About Apache MINA
Apache MINA (Multipurpose Infrastructure for Network Applications) is an abstract, event-driven asynchronous I/O API that simplifies network programming across various transport protocols like TCP/IP and UDP/IP. It provides a flexible framework for developing network applications, making it popular among developers for creating high-performance networked services.
Summary of the Vulnerability
CVE ID: CVE-2024-52046
Description: Critical remote code execution vulnerability in Apache MINA's ObjectSerializationDecoder
CVSS Score: 10.0 (Critical)
CVSS Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H
The vulnerability stems from the ObjectSerializationDecoder in Apache MINA, which uses Java's native deserialization protocol to process incoming serialized data. The decoder lacks necessary security checks and defenses, allowing attackers to exploit the deserialization process by sending specially crafted malicious serialized data, potentially leading to remote code execution.
Impact of the Vulnerability
The critical nature of CVE-2024-52046 cannot be overstated. An attacker can potentially execute arbitrary code on systems using vulnerable versions of Apache MINA by sending maliciously crafted serialized data. This vulnerability is particularly dangerous because it requires no user interaction and can be exploited remotely, giving attackers complete control over the target system.
The potential impacts include:
Unauthorized remote code execution
Complete system compromise
Data theft or manipulation
Potential use as an entry point for further network infiltration

mmediate Remediation Steps
Upgrade to Patched Versions:
Apache MINA 2.0.27
Apache MINA 2.1.10
Apache MINA 2.2.4
2. Explicitly Configure Deserialization: Use one of these methods to restrict deserialized classes:
3. Default Deny Configuration: By default, the decoder will now reject all classes unless explicitly allowed.
// Accept classes matching a specific matcher
decoder.accept(ClassNameMatcher classNameMatcher)
// Accept classes matching a regex pattern
decoder.accept(Pattern pattern)
// Accept classes using wildcard patterns
decoder.accept(String... patterns)Mitigation Strategies
Implement strict input validation
Use allowlisting for permitted serialized classes
Consider alternative serialization mechanisms
Regularly update dependencies
Conclusion
CVE-2024-52046 represents a critical security vulnerability that requires immediate attention from security professionals. By understanding the vulnerability, checking affected systems, and applying the recommended fixes, organizations can protect themselves from potential remote code execution attacks.
Stay vigilant, keep your systems updated, and prioritize security in your network applications.
