CVE-2020-4463 is an XML External Entity (XXE) injection vulnerability in IBM Maximo Asset Management versions 7.6.0.1 and 7.6.0.2. The vulnerability arises from improper restriction of XML external entity references when processing XML data, allowing remote attackers to submit crafted XML payloads. This can result in the disclosure of sensitive information or exhaustion of system memory resources. The flaw is present in the Tivoli process automation engine core component and is exploitable without authentication or user interaction.

This repository provides a Python proof-of-concept (PoC) exploit for CVE-2020-4463, an XML External Entity (XXE) vulnerability in IBM Maximo Asset Management. The repository contains two files: a Python script (CVE-2020-4463.py) and a README.md. The Python script allows an attacker to exploit two vulnerabilities: (1) unauthenticated data leakage via a crafted XML request to the /meaweb/os/mxperson REST API endpoint, and (2) XXE attacks that can read arbitrary files from the server's filesystem (demonstrated for both Windows and Linux targets). The script takes command-line arguments to select the attack type and specify the target URL. The README provides background on the vulnerability, affected versions, usage instructions, and example outputs. The exploit is a standalone PoC, not part of a framework, and is intended for educational purposes. No hardcoded IPs or domains are present; the target URL is supplied by the user.
