CyberRota Analysis

AI-Generated

The vulnerability affects the SerializingHttpMessageConverter in Java applications, which deserializes HTTP request bodies without proper class filtering, allowing for the execution of arbitrary code via crafted serialized objects. This poses a significant risk for applications using vulnerable versions of Spring Integration, as a remote, unauthenticated attacker can exploit this flaw to execute malicious code. Organizations utilizing these Spring Integration versions should prioritize patching to mitigate the risk of unauthorized access and potential system compromise.

Original NVD 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. Spring Integration 7.1.0 Spring Integration 7.0.0 - 7.0.5 Spring Integration 6.5.0 - 6.5.10 Spring Integration 6.4.0 - 6.4.12 Spring Integration 5.5.21 and earlier
