AI-analyzed exploit summary This repository contains a working proof-of-concept exploit for CVE-2025-43960, a PHP Object Injection vulnerability in Adminer < 4.8.1 via Monolog, leading to a Denial of Service (DoS) through memory manipulation. The exploit generates a large serialized payload to trigger excessive memory consumption.
Description
Adminer 4.8.1, when using Monolog for logging, allows a Denial of Service (memory consumption) via a crafted serialized payload (e.g., using s:1000000000), leading to a PHP Object Injection issue. Remote, unauthenticated attackers can trigger this by sending a malicious serialized object, which forces excessive memory usage, rendering Adminer’s interface unresponsive and causing a server-level DoS. While the server may recover after several minutes, multiple simultaneous requests can cause a complete crash requiring manual intervention.
