CVE-2023-0669 is a critical vulnerability in Fortra GoAnywhere MFT that allows unauthenticated remote code execution. The flaw is described as a pre-authentication command injection condition in the License Response Servlet caused by deserialization of untrusted, attacker-controlled data. Successful exploitation does not require prior authentication and can be performed remotely against exposed vulnerable GoAnywhere MFT instances. The issue was exploited as a zero-day in early 2023, including against hosted and on-premises deployments, and was used to create unauthorized accounts and access customer data. The vulnerability was patched in GoAnywhere MFT version 7.1.2.

This repository is a Java-based exploit for CVE-2023-0669, a pre-authentication command injection vulnerability in Fortra GoAnywhere MFT. The exploit targets the License Response Servlet (typically at /goanywhere/lic/accept), which is vulnerable due to unsafe deserialization of attacker-controlled objects. The main entry point is 'src/main/java/org/gaw/Exploit.java', which provides a command-line interface to generate a malicious serialized payload (using ysoserial gadget chains, e.g., CommonsBeanutils1), encrypt it with the appropriate AES key (matching the GoAnywhere MFT implementation), and send it to the target endpoint. The exploit supports specifying a proxy, custom endpoint path, and arbitrary commands for execution. The repository includes supporting code for payload generation, encryption, HTTP communication, and utility functions. The exploit is operational and can be used to achieve remote code execution on vulnerable GoAnywhere MFT servers. No hardcoded IPs or domains are present, but the default and expected endpoint is '/goanywhere/lic/accept'.
