Recently, researchers from the Chekmarx team discovered and released a deserialization vulnerability (CVE-2019-17564) existing in Apache Dubbo.
Apache Dubbo is a high-performance Java RPC framework. This vulnerability exists in Dubbo application which has the HTTP protocol enabled for communication. An attacker could exploit this vulnerability by submitting a POST request with a Java object, thereby completely compromising a Provider instance of Apache Dubbo.
The Dubbo HTTP instance attempts to deserialize data within the Java ObjectStream, which contains a malicious set of classes. Due to the lack of proper filtering and check, the deserialization could cause malicious code execution.
This vulnerability only affects users who enable the HTTP protocol rather than the default Dubbo protocol.
- 7.0<=Dubbo Version <=2.7.4
- 6.0 <= Dubbo Version <= 2.6.7
- Dubbo 2.5.x (no longer supported)
- Dubbo Version =2.7.5
Apache has released Dubbo 2.7.5 to fix the preceding vulnerability. Affected users are advised to upgrade as soon as possible.
