Tracked as CVE-2024-52046, the vulnerability carries a CVSS score of 10.0. It affects versions 2.0.X, 2.1.X, and 2.2.X. "The ObjectSerializationDecoder in Apache MINA uses Java's
Analysis Summary
# Vulnerability: Apache MINA Remote Code Execution via Unsafe Deserialization
## CVE Details
- CVE ID: CVE-2024-52046
- CVSS Score: 10.0 (Critical)
- CWE: (Not explicitly listed, but related to Deserialization of Untrusted Data)
## Affected Systems
- Products: Apache MINA Java network application framework
- Versions: 2.0.X, 2.1.X, and 2.2.X
- Configurations: Exploitation is contingent on invoking the `IoBuffer#getObject()` method in combination with specific classes like `ProtocolCodecFilter` and `ObjectSerializationCodecFactory`.
## Vulnerability Description
The vulnerability exists within the `ObjectSerializationDecoder` component of Apache MINA. It fails to implement adequate security checks when processing incoming serialized data using Java's native deserialization protocol. This flaw allows an unauthenticated attacker to send specially crafted, malicious serialized data, leading to potential Remote Code Execution (RCE) upon deserialization.
## Exploitation
- Status: Details on active exploitation status are not provided, but a Critical RCE suggests high interest.
- Complexity: Likely Medium to High, as specific configurations involving `IoBuffer#getObject()` and related classes are required.
- Attack Vector: Network (due to deserialization of incoming network data).
## Impact
- Confidentiality: High
- Integrity: High
- Availability: High
## Remediation
### Patches
- Users must upgrade to patched versions released by the Apache Software Foundation. (Specific fixed versions are not detailed in the summary but implied by the release of the advisory).
### Workarounds
- Users must explicitly configure and allow-list the specific classes that the decoder is permitted to accept within the `ObjectSerializationDecoder` instance, using one of the three newly introduced methods. Upgrading alone is insufficient without this configuration change.
## Detection
- Detection methods are not explicitly detailed, but monitoring for unexpected deserialization payloads targeting the `ObjectSerializationDecoder` within MINA applications would be key.
