Infinispan permits improper deserialization of trusted data via XML and JSON transcoders under certain server configurations. A user with authenticated access to the server could send a malicious object to a cache configured to accept certain types of objects, achieving code execution and possible further attacks. Versions 9.0.3.Final, 9.1.7.Final, 8.2.10.Final, 9.2.2.Final, 9.3.0.Alpha1 are believed to be affected.
It was found that the Hotrod client in Infinispan before 9.2.0.CR1 would unsafely read deserialized data on information from the cache. An authenticated attacker could inject a malicious object into the data cache and attain deserialization on the client, and possibly conduct further attacks.
