Spring Framework is vulnerable to security bypass via mvcRequestMatcher pattern mismatch

Critical severity GitHub Reviewed Published Mar 28, 2023 to the GitHub Advisory Database • Updated Mar 14, 2024

Package

maven org.springframework:spring (Maven)

Affected versions

>= 6.0.0, < 6.0.7
>= 5.3.0, < 5.3.26

Patched versions

6.0.7
5.3.26

Description

Spring Framework running version 6.0.0 - 6.0.6 or 5.3.0 - 5.3.25 using "**" as a pattern in Spring Security configuration with the mvcRequestMatcher creates a mismatch in pattern matching between Spring Security and Spring MVC, and the potential for a security bypass.

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.
