AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H

A deserialization flaw was discovered in the jackson-databind in versions before 2.8.10 and 2.9.1, which could allow an unauthenticated user to perform code execution by sending the maliciously crafted input to the readValue method of the ObjectMapper. This issue extends the previous flaw CVE-2017-7525 by blacklisting more classes that could be used maliciously.

Remedy

Mitigation to this problem is to not trigger polymorphic desrialization globally by using: objectMapper.enableDefaultTyping() and rather use @JsonTypeInfo on the class property to explicitly define the type information.

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

It was found that logback is vulnerable to a deserialization issue. Logback can be configured to allow remote logging through SocketServer/ServerSocketReceiver interfaces that can accept untrusted serialized data. Authenticated attackers on the adjacent network can leverage this vulnerability to execute arbitrary code through deserialization of custom gadget chains.
