org.springframework.security:spring-security-config@5.8.4 vulnerabilities

org.springframework.security:spring-security-config is a security configuration package for Spring Framework.

Affected versions of this package are vulnerable to Authorization Bypass due to the use of String.toLowerCase() and String.toUpperCase() that have Locale dependent exceptions, which results in authorization rules not working properly.

Upgrade org.springframework.security:spring-security-config to version 5.7.14, 5.8.16, 6.2.8, 6.3.5 or higher.

org.springframework.security:spring-security-config is a security configuration package for Spring Framework.

Affected versions of this package are vulnerable to Incorrect Permission Assignment for Critical Resource via the spring-security.xsd file due to being world writable. An attacker with access to the file system could extract this file and modify it.

Upgrade org.springframework.security:spring-security-config to version 5.7.11, 5.8.7, 6.0.7, 6.1.4 or higher.

org.springframework.security:spring-security-config is a security configuration package for Spring Framework.

Affected versions of this package are vulnerable to Access Control Bypass. When using ** as a pattern in Spring Security configuration for WebFlux a mismatch in pattern matching is created between Spring Security and Spring WebFlux, resulting in a security bypass.

Note:

The fixed versions require Spring Framework versions:

1. 6.0.11+

2. 5.3.29+

3. 5.2.25+

Note: The Spring security team have published information about an existing PoC, but have not shared the PoC itself publicly, therefore we don't currently have the ability to verify it.

Upgrade org.springframework.security:spring-security-config to version 5.6.12, 5.7.10, 5.8.5, 6.0.5, 6.1.2 or higher.

org.springframework.security:spring-security-config is a security configuration package for Spring Framework.

Affected versions of this package are vulnerable to Improper Authorization due to improper validation in the requestMatchers, leading to authorization rule misconfiguration when the application uses requestMatchers(String) and multiple servlets, one of them being Spring MVC’s DispatcherServlet.

Notes:

An application is only vulnerable when all of the following are true:

1. Spring MVC is on the classpath.

2. Spring Security is securing more than one servlet in a single application (one of them being Spring MVC’s DispatcherServlet).

3. The application uses requestMatchers(String) to refer to endpoints that are not Spring MVC endpoints.

Upgrade org.springframework.security:spring-security-config to version 5.8.5, 6.0.5, 6.1.2 or higher.
