Information about the vulnerability Spring4shell
Spring4Shell vulnerability needs several coexisting requirements to be exploitable.
- Vulnerable version of Spring Framework (upgrade solves completely the issue)
- Vulnerable version of Apache Tomcat (upgrade neutralize the attack vector even if Spring Framework version is vulnerable)
- Java 9 or higher
- spring-webmvc or spring-webflux dependency.
We have enhanced the plugin for the authenticated version check (HID-2-1-347322) by adding a check for the presence and version of Apache Tomcat on the scanned system.
If a vulnerable version of Spring Framework is detected, we advise upgrading it as the best solution.
In case also Apache Tomcat is detected and vulnerable, we report the installed Tomcat version and advice to update to the relevant safe release of Tomcat as a Mitigation in case upgrading Spring Framework is not a viable choice.
In this way, the test is more accurate, in that it reveals more information and solutions about the exploit scenario present in the customer system. Of course, the solution section also provides insight into other mitigation options.
