Code injection

Each Apache Dubbo server will set a serialization id to tell the clients which serialization protocol it is working on. But for Dubbo versions before 2.7.8 or 2.6.9, an attacker can choose which serialization id the Provider will use by tampering with the byte preamble flags, aka, not following t...

CVE-2021-25641 Dubbo Zookeeper does not check serialization id

Each Apache Dubbo server will set a serialization id to tell the clients which serialization protocol it is working on. But for Dubbo versions before 2.7.8 or 2.6.9, an attacker can choose which serialization id the Provider will use by tampering with the byte preamble flags, aka, not following t...

CVE-2021-25641

CVE-2021-25641 affects Apache Dubbo servers prior to 2.7.8 and 2.6.9. The vulnerability arises when a provider’s byte preamble flags are tampered with, allowing an attacker to override the server’s chosen serialization protocol and trigger a weak deserializer (e.g., Kryo or FST) in scope. This en...

Insecure deserialization in Wire

Due to how Wire handles type information in its serialization format, malicious payloads can be passed to a deserializer. e.g. using a surrogate on the sender end, an attacker can pass information about a different type for the receiving end. And by doing so allowing the serializer to create any...

Command Execution Vulnerability in XStream

XStream is an open source Java class library , it is mainly used to serialize objects into XML JSON or deserialize objects . A command execution vulnerability exists in XStream. An attacker could exploit the vulnerability to execute arbitrary code in the context of an affected application run by ...
