spring4shell-scan

spring4shell-scan

A fully automated, reliable, and accurate scanner for finding Spring4Shell and Spring Cloud RCE vulnerabilities

Features

  • Support for lists of URLs.
  • Fuzzing for more than 10 new Spring4Shell payloads (previously seen tools uses only 1-2 variants).
  • Fuzzing for HTTP GET and POST methods.
  • Automatic validation of the vulnerability upon discovery.
  • Randomized and non-intrusive payloads.
  • WAF Bypass payloads.

Description

The Spring4Shell RCE is a critical vulnerability that FullHunt has been researching since it was released. We worked with our customers in scanning their environments for Spring4Shell and Spring Cloud RCE vulnerabilities.

We're open-sourcing an open detection scanning tool for discovering Spring4Shell (CVE-2022-22965) and Spring Cloud RCE (CVE-2022-22963) vulnerabilities. This shall be used by security teams to scan their infrastructure, as well as test for WAF bypasses that can result in achieving successful exploitation of the organization's environment.

If your organization requires help, please contact (team at fullhunt.io) directly for a full attack surface discovery and scanning for the Spring4Shell vulnerabilities.

Usage

$ ./spring4shell-scan.py -h
[•] CVE-2022-22965 - Spring4Shell RCE Scanner
[•] Scanner provided by FullHunt.io - The Next-Gen Attack Surface Management Platform.
