Loading vulnerability…
CVE-2021-3007 is an insecure PHP object deserialization vulnerability affecting laminas-http versions before 2.14.2 and Zend Framework 3.0.0. The issue involves Zend\Http\Response\Stream::__destruct(), whose cleanup behavior can invoke file deletion on attacker-influenced object state after a crafted serialized object is deserialized. The built-in gadget behavior supports arbitrary file deletion; where the application or its dependencies expose additional suitable gadgets, it may be chained to achieve remote code execution.

This repository provides a complete proof-of-concept (PoC) exploit for CVE-2021-3007, a critical PHP deserialization vulnerability in Zend\Http\Response\Stream (laminas-http <2.14.2, zend-http <=2.14.1). The exploit leverages a vulnerable endpoint (vulnerable-app/index.php) that unserializes user-supplied data, allowing an attacker to send a crafted serialized object that triggers arbitrary file write on the server. The main exploit logic is implemented in exploit.php, which generates the payload and sends it via HTTP POST to the target. The repository includes a Docker environment (Dockerfile, docker-compose.yml) for easy setup of a vulnerable test application, and a bash script (test.sh) to automate exploitation and verification. The exploit demonstrates the ability to write arbitrary files, which can be leveraged for remote code execution. The repository is structured for educational and authorized security testing purposes, and includes documentation and references for further reading.
