CVE-2023-0669 is a critical vulnerability in Fortra GoAnywhere MFT caused by unsafe deserialization of attacker-controlled data in the License Response Servlet, enabling pre-authentication command injection and remote code execution. The flaw is associated with the product’s license-processing functionality, where an unauthenticated attacker can supply a crafted serialized object that is deserialized by the application before authentication. Successful exploitation allows arbitrary code execution on the GoAnywhere MFT server. The issue was exploited in the wild as a zero-day in early 2023 and was patched by Fortra in GoAnywhere MFT version 7.1.2.

This repository contains a single Metasploit module targeting Fortra GoAnywhere MFT's unsafe Java deserialization vulnerability (CVE-2023-0669). The exploit leverages a POST request to the /goanywhere/lic/accept endpoint, sending a malicious, AES-encrypted, serialized Java object (CommonsBeanutils1 gadget) to trigger remote code execution. The module supports both Version 1 and Version 2 encryption schemes, with hardcoded keys and IVs for each. The exploit is operational and allows the attacker to execute arbitrary commands on both Unix and Windows platforms, provided the target is vulnerable and accessible. The code is structured as a standard Metasploit exploit module, with configuration options for the endpoint, encryption parameters, and payload. No external network endpoints or IPs are hardcoded; the main fingerprintable endpoint is the vulnerable URI. The repository is a single Ruby file, typical for Metasploit modules.
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'.
