Quick assessment
Affected
Spring Spring Integration
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.
使用原始的 对传入 HTTP 请求的 body 进行反序列化，且未做任何类过滤。任何携带 且 body 可解析为 类型的请求，都会通过 直接读取。如果应用程序在入站 HTTP 端点上使用了该转换器，且其 classpath 中存在已知的 Java 反序列化“gadget”，那么远程且未认证的攻击者即可实现任意代码执行。 受影响版本： Spring Integration 7.1.0 Spring Integration 7.0.0 - 7.0.5 Spring Integration 6.5.0 - 6.5.10

Vulnerability Title
Unsafe Java deserialization in SerializingHttpMessageConverter — remote code execution
Source: CVE Program / CVE List V5
Vulnerability Description
SerializingHttpMessageConverter deserializes the body of incoming HTTP requests with a raw java.io.ObjectInputStream and no class filtering. Any request with Content-Type application/x-java-serialized-object whose body resolves to a Serializable type is read directly via readObject(). If an application using this converter on an inbound HTTP endpoint has any known Java deserialization "gadget" on its classpath, a remote, unauthenticated attacker can achieve arbitrary code execution.
