Unauthenticated RCE in Oracle WebLogic Server Web Services

IdentifiersCVE-2019-2725CWE-502

CVE-2019-2725 is a critical unsafe deserialization vulnerability in the Oracle WebLogic Server component of Oracle Fusion Middleware, specifically the Web Services subcomponent. Affected supported versions include 10.3.6.0.0 and 12.1.3.0.0. The flaw is remotely exploitable over HTTP without authentication and has been described by Oracle and multiple security reports as easily exploitable. Public reporting and advisories characterize exploitation as occurring via WebLogic web service endpoints, including AsyncResponderService, allowing attacker-supplied serialized data to be processed and resulting in arbitrary command/code execution on the target server.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation can allow a remote unauthenticated attacker to execute arbitrary code or commands on the vulnerable Oracle WebLogic Server with the privileges of the WebLogic process, which can lead to complete takeover of the server. Oracle rates the issue at CVSS 3.0 9.8 with high confidentiality, integrity, and availability impact. In the wild, the vulnerability has been used to deploy ransomware including Sodinokibi/REvil and other malware, demonstrating practical outcomes including system compromise, payload staging, encryption of victim systems, and broader post-exploitation activity.

Mitigation

If you can’t patch tonight, do this now.

If immediate patching is not possible, restrict network access to vulnerable WebLogic HTTP endpoints to trusted sources only, especially internet exposure to Web Services endpoints. Implement segmentation and ingress filtering around WebLogic servers, monitor for suspicious HTTP POST requests and unexpected use of web service endpoints such as AsyncResponderService, and review for indicators of compromise including web shells, unexpected child processes from WebLogic, and malicious downloads. Centralized logging and egress restrictions can reduce attacker success, but these are temporary measures and not substitutes for patching.

Remediation

Patch, then assume compromise.

Apply Oracle’s out-of-band security update released on 2019-04-26 for CVE-2019-2725 and upgrade to the fixed/supported WebLogic versions specified by Oracle. Ensure all relevant WebLogic Server patches are installed and that the deployment remains on a version covered by Premier or Extended Support so future security fixes can be obtained. Because exploitation has been widely observed, exposed systems should also be reviewed for compromise after patching.

Oracle-Weblogic-Server-AsyncResponseService-Deserialization-Remote-Code-Execution-CVE-2019-2725MaturityPoCVerified exploit

Repository contains a single Python exploit script and a README describing CVE-2019-2725 (Oracle WebLogic unauthenticated RCE via AsyncResponseService). The exploit (web_logic_CVE-2019-2725.py) uses the requests library to POST a crafted SOAP/XML payload to a user-supplied target URL (intended to be /_async/AsyncResponseService). It first performs a lightweight vulnerability check by POSTing with SOAP headers and interpreting HTTP 500 with a specific SOAP faultcode or HTTP 202 as potentially vulnerable. If positive, it sends a SOAP envelope with a WorkContext header that instantiates java.lang.ProcessBuilder to run '/bin/bash -c <command>' where <command> is provided on the command line (XML-escaped). Primary capability is remote command execution; the README demonstrates using it to obtain a reverse shell (e.g., netcat listener on port 2323). The code assumes a Unix-like target due to the hardcoded /bin/bash and does not include advanced features like target discovery, multi-target scanning, or payload staging.

javaserializetoolsMaturityPoCVerified exploit

This repository is a Java-based GUI tool for exploiting Oracle WebLogic Server deserialization vulnerabilities, specifically CVE-2017-10271 and CVE-2019-2725, affecting versions 10 and 12. The tool provides a graphical interface (Main.java) allowing users to check for vulnerabilities, execute arbitrary commands, upload files, and retrieve server paths on vulnerable WebLogic instances. The core logic is implemented in the 'paylaod' package, with separate classes for each CVE and WebLogic version. The tool constructs and sends crafted SOAP/XML payloads to specific WebLogic endpoints (such as /wls-wsat/CoordinatorPortType and /_async/AsyncResponseService) to trigger the vulnerabilities. The 'tools' package provides supporting utilities for HTTP requests, encoding, and other helper functions. The repository is operational, providing working exploit code with customizable payloads, and is not part of a larger exploit framework.

CVE-2019-2725MaturityPoCVerified exploit

This repository provides a working exploit for CVE-2019-2725, a critical remote code execution vulnerability in Oracle WebLogic Server (wls9-async component). The exploit leverages a Java deserialization vulnerability by sending a crafted SOAP XML payload containing a malicious serialized object (using the TemplatesImpl gadget chain) to the /wls-wsat/CoordinatorPortType endpoint. The Java files (JDK7u21.java and ResultBaseExec.java) are used to generate the payload and execute arbitrary system commands on the target server. The repository includes example payloads for both command execution and echoing results, as well as documentation and sample HTTP requests. The exploit is operational and demonstrates command execution with output returned in the HTTP response, targeting WebLogic versions 10.3.6 and 12.1.3.

CVE-2019-2725MaturityPoCVerified exploit

This repository contains a Python-based universal exploit tool targeting multiple critical vulnerabilities in Oracle WebLogic Server: CVE-2017-3506, CVE-2017-10271, CVE-2019-2725, and CVE-2019-2729. The main script, 'weblogic_exploit.py', allows attackers to craft and deliver SOAP/XML payloads that exploit deserialization and XMLDecoder flaws, enabling remote command execution on vulnerable WebLogic instances. The tool supports several payload types: direct command execution (process_builder, event_data), serialized object deserialization (unit_of_work_change_set, requiring ysoserial), and remote XML payload fetching (fs_xml_app_ctx). It can target different WebLogic endpoints, notably '/wls-wsat/CoordinatorPortType11' for command output and '/_async/AsyncResponseService' for blind execution. The exploit is highly customizable, supporting proxying, custom commands, and payload hosting (e.g., via file.io). The README provides detailed usage instructions, payload templates, and example commands. The repository is operational and suitable for real-world exploitation, not just proof-of-concept.

WeblogicMaturityPoCVerified exploit

This repository is a proof-of-concept exploit for Oracle WebLogic Server vulnerabilities CVE-2019-2725 and CVE-2019-2729. It contains a Python script ('weblogic_get_webshell.py') that automates exploitation by sending crafted SOAP/XML payloads to vulnerable WebLogic endpoints. The script can target a single URL or multiple URLs listed in 'url_list.txt'. The main capabilities are remote command execution and uploading a persistent JSP webshell to the target server. The payloads are stored in separate files (payload3.txt, and references to payload.txt and payload2.txt, which are missing in this archive). The exploit targets the '/_async/AsyncResponseService' and '/wls-wsat/CoordinatorPortType' endpoints on the WebLogic server. The repository is operational, providing a working exploit with a hardcoded payload, and is not part of a larger framework. The README provides usage instructions in Chinese, indicating how to run the exploit for single or multiple targets.
