CVE-2024-22399 | Apache Seata: Remote Code Execution vulnerability via Hessian Deserialization in Apache Seata Server

Deserialization of Untrusted Data vulnerability in Apache Seata.  When developers disable authentication on the Seata-Server and do not use the Seata client SDK dependencies, they may construct uncontrolled serialized malicious requests by directly sending bytecode based on the Seata private protocol. This issue affects Apache Seata: 2.0.0, from 1.0.0 through 1.8.0. Users are recommended to upgrade to version 2.1.0/1.8.1, which fixes the issue.

9.8 3.1 CRITICAL
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
