Spring Security uses insufficiently random values

Moderate severity GitHub Reviewed Published Apr 16, 2019 to the GitHub Advisory Database • Updated Jan 28, 2023

Package

maven org.springframework.security:spring-security-core (Maven)

Affected versions

>= 4.2.0, < 4.2.12
>= 5.0.0, < 5.0.12
>= 5.1.0, < 5.1.5

Description

Spring Security versions 4.2.x prior to 4.2.12, 5.0.x prior to 5.0.12, and 5.1.x prior to 5.1.5 contain an insecure randomness vulnerability when using SecureRandomFactoryBean#setSeed to configure a SecureRandom instance. In order to be impacted, an honest application must provide a seed and make the resulting random material available to an attacker for inspection.

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.
