Affected packages

• Maven com.fasterxml.jackson.core:jackson-databind: >= 2.9.0, < 2.9.10.1 → fixed in 2.9.10.1 • Maven com.fasterxml.jackson.core:jackson-databind: >= 2.7.0, < 2.8.11.5 → fixed in 2.8.11.5 • Maven com.fasterxml.jackson.core:jackson-databind: < 2.6.7.3 → fixed in 2.6.7.3

Description

A Polymorphic Typing issue was discovered in FasterXML jackson-databind 2.0.0 prior to 2.9.10.1, 2.8.11.5, and 2.6.7.3. When Default Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint and the service has the apache-log4j-extra (version 1.2.x) jar in the classpath, and an attacker can provide a JNDI service to access, it is possible to make the service execute a malicious payload.
