Loading vulnerability…
CVE-2024-22243 is an open redirect and server-side request forgery vulnerability in Spring Framework's spring-web component. Applications are affected when they use UriComponentsBuilder to parse an externally supplied URL, make a security decision by validating the parsed host, and subsequently use that URL. Crafted URL input can cause host-validation logic to be bypassed because the parsed host does not reliably represent the effective destination used by the application.

This repository is a proof-of-concept (POC) exploit and detection toolkit for CVE-2024-22243, a URL parsing vulnerability in the Java Spring Framework. The repository contains a vulnerable web application (src/main/java/com/seanpesce/spring/VulnerableWebApp.java) that exposes two main endpoints: '/redirect' (demonstrating an open redirect) and '/health-check' (demonstrating server-side request forgery, SSRF). The application uses a list of trusted hosts, but due to Spring's abnormal URL parsing, an attacker can bypass these checks with specially crafted URLs. The README provides detailed background, exploitation examples, and usage instructions. The repository also includes Semgrep rules (in the 'semgrep/' directory) for detecting vulnerable code patterns in Java/Spring projects. The project is built with Maven and can be run directly or via Docker. No weaponized payloads are included; the code is intended for demonstration and detection purposes.

A vulnerability affecting Spring Web applications that parse externally supplied URLs with UriComponentsBuilder and validate their hosts. Such validation may fail to prevent open redirect or SSRF attacks. The reference assigns a CVSS v3 base score of 8.1 and recommends updating org.springframework:spring-web to 5.3.25-echo.1 or later.
