Affected versions:
- Apache MINA 2.0 through 2.0.26 unknown
- 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 will be 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
* {@link
org.apache.commons.io.FilenameUtils#wildcardMatch(String, String)
FilenameUtils.wildcardMatch}
*/
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.
