CVE-2019-2888 is an information disclosure vulnerability in the EJB Container component of Oracle WebLogic Server (versions 10.3.6.0.0, 12.1.3.0.0, and 12.2.1.3.0). The vulnerability allows an unauthenticated attacker with network access via HTTP to read a subset of data accessible to the WebLogic Server, due to improper access controls or data exposure in the EJB Container.

This repository contains an operational exploit for CVE-2019-2888, an XML External Entity (XXE) vulnerability in Oracle WebLogic Server's EJBTaglibDescriptor class. The exploit consists of a Python script (weblogic.py) that crafts and sends a serialized Java object containing a malicious XML payload to a target WebLogic server over the T3 protocol (default port 7001). The payload references an attacker-controlled DTD file (served over HTTP) and exfiltrates file contents via FTP. The README.md provides detailed instructions, including how to set up the required DTD and FTP/HTTP servers for exfiltration, and demonstrates the attack process. The Java file (EJBTaglibDescriptor.java) is a decompiled version of the vulnerable class, included for reference. The exploit is not part of a framework and is a standalone operational exploit script. The main entry point is weblogic.py, which requires the attacker to specify the target IP and port, as well as the attacker's own server details for DTD and FTP exfiltration. The exploit enables attackers to read arbitrary files from the target server, demonstrating the impact of the XXE vulnerability.
