CVE-2023-0669 is a critical remote code execution vulnerability in Fortra GoAnywhere MFT caused by unsafe deserialization of attacker-controlled data in the License Response Servlet. The flaw is reachable without authentication and has been described as a pre-authentication command injection condition arising from deserialization of an arbitrary object supplied by a remote attacker. Successful exploitation allows arbitrary code execution on the GoAnywhere MFT server. The issue affects GoAnywhere MFT prior to the vendor fix and was patched in version 7.1.2. The vulnerability was exploited in the wild as a zero-day in early 2023, including by ransomware and data-extortion actors.

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'.
