CVE-2020-36180Network attack vector

Remote code execution via unblocked DBCP gadget

Published Jan 6, 2021 · Updated Aug 4, 2024

Deserialization in FasterXML jackson-databind before 2.9.10.8 allows remote attackers to execute code through a crafted polymorphic payload. SubTypeValidator failed to block org.apache.commons.dbcp2.cpdsadapter.DriverAdapterCPDS and related shaded variants as unsafe subtypes. Exploitation requires attacker-controlled input, Default Typing or equivalent class-based polymorphism, and a matching DBCP gadget on the classpath.
