Background
The jackson-databind package is a popular Java library used for serializing and deserializing JSON data. It provides functionality to convert JSON data to Java objects and vice versa. This vulnerability affects versions prior to 2.8.10 and 2.9.1 of the package. The vulnerability allows an unauthenticated user to execute arbitrary code by exploiting a deserialization flaw in the readValue method of the ObjectMapper class. This flaw is an extension of a previous vulnerability (CVE-2017-7525) and adds additional vulnerable classes to the blacklist.
Vulnerability Detail
The deserialization flaw in jackson-databind allows an attacker to execute arbitrary code by sending specially crafted input to the readValue method of the ObjectMapper class. This can lead to remote code execution, enabling the attacker to take control of the affected system. The vulnerability is considered critical with a CVSS score of 9.8. It affects both Maven versions of the package: com.fasterxml.jackson.core:jackson-databind:2.8.10 and com.fasterxml.jackson.core:jackson-databind:2.9.1.
