Deserialization of Untrusted Data

High severity GitHub Reviewed Published Jun 15, 2020 to the GitHub Advisory Database • Updated Mar 1, 2024

Package

maven com.fasterxml.jackson.core:jackson-databind (Maven)

Affected versions

>= 2.7.0, <= 2.7.9.3
>= 2.8.0, <= 2.8.11.1
>= 2.9.0, < 2.9.6

Patched versions

Description

An issue was discovered in FasterXML jackson-databind prior to 2.7.9.4, 2.8.11.2, and 2.9.6. When Default Typing is enabled (either globally or for a specific property), the service has the Oracle JDBC jar in the classpath, and an attacker can provide an LDAP service to access, it is possible to make the service execute a malicious payload.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
