Deserialization of Untrusted Data in FasterXML jackson-databind

Moderate severity GitHub Reviewed Published Jul 5, 2019 to the GitHub Advisory Database • Updated Mar 15, 2024

Package

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

Affected versions

>= 2.9.0, < 2.9.9.1
>= 2.8.0, < 2.8.11.4
>= 2.7.0, < 2.7.9.6
>= 2.0.0, < 2.6.7.3

Patched versions

2.9.9.1
2.8.11.4
2.7.9.6
2.6.7.3

Description

FasterXML jackson-databind 2.x before 2.9.9.1 might allow attackers to have a variety of impacts by leveraging failure to block the logback-core class from polymorphic deserialization. Depending on the classpath content, remote code execution may be possible.

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.
