Quick assessment

Affected
Apache Software Foundation Apache MINA
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Apache MINA是美国阿帕奇（Apache）基金会的一款网络应用程序框架。该产品主要用于开发高性能和高可伸缩性的网络应用程序。 Apache MINA存在代码问题漏洞，该漏洞源于resolveProxyClass未覆盖导致acceptMatchers过滤器绕过以及允许列表类的静态初始化器触发，可能导致反序列化攻击。

Vulnerability Title
Apache MINA: Critical Deserialization Allow-list Bypass via resolveProxyClass - ZDRES-232
Source: CVE Program / CVE List V5
Vulnerability Description
ZDRES-232: resolveProxyClass Not Overridden - acceptMatchers Filter Bypass via java.lang.reflect.Proxy Assessment: Fully addressed. When the serialised stream contains a TC_PROXYCLASSDESC (the marker for a java.lang.reflect.Proxy ), JDK’s ObjectInputStream.readProxyDesc() is dispatched. JDK then calls the default ObjectInputStream.resolveProxyClass(interfaces) implementation, which performs Class.forName(intf, false, latestUserDefinedLoader()) for EACH interface name and constructs the proxy class — bypassing the accepted classes list . ZDRES-233: Class.forName(name, initialize=true, classLoader) in readClassDescriptor Triggers Static Initialiser of Allow-Listed Classes Assessment: Fully addressed. For ANY class on the allow-list, deserialising a stream that names it triggers the class’s (static initialiser) BEFORE any instance is constructed. This means an attacker who supplies a class name on the allow-list (e.g., the developer wrote accept(“com.myapp.*") , attacker supplies com.myapp.SomeClass ) causes <clinit> of SomeClass — and many real-world classes have side-effecting static initialisers Both issues have been fixed.
