Loading vulnerability…
CVE-2023-24998 is a denial-of-service vulnerability in Apache Commons FileUpload before version 1.5. The multipart upload processing functionality does not limit the number of request parts it processes. An attacker can submit a malicious upload or a sequence of uploads containing excessive request parts, causing excessive processing and service disruption.

This repository is a proof-of-concept (PoC) exploit for CVE-2023-24998, a vulnerability in Apache Commons FileUpload (and indirectly in Spring Boot applications using it) where the fileCountMax parameter is not enforced, allowing attackers to upload an excessive number of files or parameters in a multipart request. The repository is structured as a Spring Boot project with a custom Tomcat configuration and a file upload controller. The main exploit is implemented in the test file (src/test/java/com/example/cve202324998/controller/FileUploadControllerTest.java), which sends a multipart request to the /fileUpload endpoint with 10 files and 100,000 text parameters. The bash script (http/makeMultipart.sh) can generate a large multipart payload for manual testing. The exploit demonstrates how an attacker could abuse the lack of proper limits to exhaust server resources or bypass security controls. The repository targets Java web applications using Apache Commons FileUpload (1.3.3 to 1.5) and/or Tomcat 9.0.71+ with specific multipart resolver configurations.
