GHSA-8297-v2rf-2p32
Apache MINA vulnerable to Deserialization of Untrusted Data
Quick fix
GHSA-8297-v2rf-2p32 — org.apache.mina:mina-core: upgrade to the fixed version with the command below.
# pom.xml: bump <version>2.0.28</version> for org.apache.mina:mina-coreDetails
Apache MINA's AbstractIoBuffer.resolveClass() contains two branches, one of them (for static classes or primitive types) does not check the class at all, bypassing the classname allowlist and allowing arbitrary code to be executed.
The fix checks if the class is present in the accepted class filter before calling Class.forName().
Affected versions are Apache MINA 2.0.0 <= 2.0.27, 2.1.0 <= 2.1.10, and 2.2.0 <= 2.2.5.
The problem is resolved in Apache MINA 2.0.28, 2.1.11, and 2.2.6 by applying the classname allowlist earlier.
Affected are applications using Apache MINA that call IoBuffer.getObject().
Applications using Apache MINA are advised to upgrade.
