The host is installed with SpringSource Spring Framework 6.0.0 through 6.0.6 or 5.3.0 through 5.3.25 and is prone to a security bypass vulnerability. A flaw is present in the application, which fails to properly handle regex pattern in spring security configuration. On successful exploitation, 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.
