Outbreak Alert: VMWare Spring4Shell Vulnerability

This article describes the Spring4Shell vulnerability assessment with FortiDAST.

CVE-2022-22965 vulnerability is a 0-day exploit that was discovered on a popular Java lightweight open source framework: Spring Framework.

This zero-day can result in a remote code execution, allowing the attacker to get full control of the target.

Detection against that vulnerability is empowered by the FortiDAST Scripting Engine (FSE).

This technology enables FortiDAST to assess remotely with high level of confidence if an asset is vulnerable to a specific vulnerability by testing the disarmed exploit against the asset itself.

To configure the scan, you will need to enable the FSE group signature 'spring-framework' which will select the underlying script 'CVE-2022-22965 Spring Framework 5.2.x / 5.3.x Remote Code Execution Vulnerability'.

For reference, a step-by-step guide on how to configure FortiDAST to trigger FSE can be found on Fortinet’s blog.
