SCA: security update for com.alibaba:dubbo, org.apache.dubbo:dubbo (GHSA-v2rg-8cwr-75g8)
critical Tenable Cloud Security Plugin ID 419018
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- 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 the server's
instruction. This means that if a weak deserializer such as the Kryo and FST are somehow in code scope
(e.g. if Kryo is somehow a part of a dependency), a remote unauthenticated attacker can tell the Provider
to use the weak deserializer, and then proceed to exploit it. (CVE-2021-25641)
