Summary
A flaw was found in Spring Integration. The SerializingHttpMessageConverter component deserializes incoming HTTP request bodies without proper class filtering.
A remote, unauthenticated attacker can exploit this by sending a specially crafted HTTP request. If a known Java deserialization 'gadget' is present on the application's classpath, this can lead to arbitrary code execution.
When processing HTTP requests with Content-Type application/x-java-serialized-object, the converter invokes ObjectInputStream.readObject() on the request body without class filtering or type validation. A remote, unauthenticated attacker can supply a malicious serialized payload.
Red Hat severity: Important — CVSS 8.1 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H). Weakness: CWE-502.
Affected Red Hat products: Red Hat Fuse 7. Red Hat does not currently list a fixing RHSA for this CVE.

Mitigation checklist
- Do not accept application/x-java-serialized-object content types on HTTP inbound endpoints, or configure custom HttpMessageConverter instances that enforce explicit ObjectInputFilter allowlists before deserialization occurs.
