CVE-2021-3007 is an insecure deserialization vulnerability in Laminas Project laminas-http before 2.14.2 and in Zend Framework 3.0.0. The issue is associated with the Zend\Http\Response\Stream class, specifically behavior reachable through its __destruct method. When an application unserializes attacker-controlled PHP object data and the relevant class is available, a crafted object can trigger unsafe destructor behavior involving stream-related properties and cleanup logic. Documented exploitation paths include use of a gadget chain based on Zend\Http\Response\Stream that can perform arbitrary file deletion, and the issue may be chainable with other gadgets present in the target application to achieve remote code execution. The vulnerability is therefore library-level, but exploitation depends on application code exposing an unsafe unserialize() path for untrusted input.

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.
