The MINA project is pleased to announce the MINA 2.2.4, 2.1.10 and
2.0.27 release.
**MINA** applications using unbounded deserialization may allow **RCE**
(see https://www.cve.org/CVERecord?id=CVE-2024-52046).
Affected versions:
- Apache MINA 2.0 through 2.0.26
- Apache MINA 2.1 through 2.1.9
- Apache MINA 2.2 through 2.2.3
Description:
The *ObjectSerializationDecoder* in Apache **MINA** uses 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.
This issue affects **MINA** core versions 2.0.X, 2.1.X and 2.2.X, and is
fixed by the releases 2.0.27, 2.1.10 and 2.2.4.
It's also important to note that an application using **MINA** core
library will only be affected if the *IoBuffer#getObject()* method is
called, and this specific method is potentially called when adding a
*ProtocolCodecFilter* instance using the
*ObjectSerializationCodecFactory* class in the filter chain. If your
application is specifically using those classes, you have to upgrade to
the latest version of **MINA** core library.
**Upgrading will not be enough: you also need to explicitly allow the
classes the decoder will accept in the *ObjectSerializationDecoder*
instance, using one of the three new methods:**
/**
* Accept class names where the supplied ClassNameMatcher matches for
* deserialization, unless they are otherwise rejected.
*
* @param classNameMatcher the matcher to use
*/
public void accept(ClassNameMatcher classNameMatcher)
/**
* Accept class names that match the supplied pattern for
* deserialization, unless they are otherwise rejected.
*
* @param pattern standard Java regexp
*/
public void accept(Pattern pattern)
/**
* Accept the wildcard specified classes for deserialization,
* unless they are otherwise rejected.
*
* @param patterns Wildcard file name patterns as defined by
*
org.apache.commons.io.FilenameUtils#wildcardMatch(String, String)
*/
public void accept(String... patterns)
By default, the decoder will reject *all* classes that will be present
in the incoming data.
Note: The **FtpServer**, **SSHd** and **Vysper** sub-project are not
affected by this issue.
