1. Introduction
Apache OFBiz Detection indicates that an open source enterprise resource planning (ERP) system is running on a remote web server. Apache OFBiz includes several web applications, and detecting its presence suggests potential exposure of these applications to attack. This vulnerability impacts the confidentiality, integrity, and availability of data processed by the ERP system.
2. Technical Explanation
Apache OFBiz is an open source ERP system that bundles multiple web applications. Detection indicates one or more of these applications are accessible on the network. An attacker could exploit vulnerabilities within these bundled applications to gain unauthorized access, execute code, or compromise data. The preconditions for exploitation depend on the specific application and its configuration.
- Root cause: The presence of potentially vulnerable web applications bundled with Apache OFBiz.
- Exploit mechanism: An attacker could use known vulnerabilities in the detected web applications to gain access to sensitive information or execute arbitrary code. For example, a SQL injection vulnerability in one of the web apps could allow an attacker to read data from the underlying database.
- Scope: Apache OFBiz versions are affected; specific vulnerable application versions vary.
3. Detection and Assessment
Confirming whether a system is running Apache OFBiz can be done through quick checks of web server responses or more thorough scanning methods.
- Quick checks: Access the default OFBiz URL (typically http://{target_ip}:8080) in a web browser. A login page or OFBiz welcome screen indicates presence.
- Scanning: Nessus plugin ID 16293 can detect Apache OFBiz installations. This is an example only; other scanners may also provide detection capabilities.
- Logs and evidence: Web server access logs may show requests to the OFBiz application context (e.g., /ofbiz).
curl -I http://{target_ip}:80804. Solution / Remediation Steps
The primary solution is to secure or remove the Apache OFBiz installation.
4.1 Preparation
- Services: Stop the Apache OFBiz service if possible, depending on business requirements.
4.2 Implementation
- Step 1: If the application is not required, uninstall Apache OFBiz completely using the appropriate package manager for your operating system.
- Step 2: If the application is required, update to the latest stable version of Apache OFBiz from https://ofbiz.apache.org/.
- Step 3: Review and harden the configuration of all web applications bundled with OFBiz.
4.3 Config or Code Example
No specific config change is applicable; this vulnerability requires either removal or updating to a secure version.
4.4 Security Practices Relevant to This Vulnerability
- Least privilege: Limit access to the OFBiz server and applications to only authorized users.
- Patch cadence: Regularly update Apache OFBiz and its bundled applications with security patches.
4.5 Automation (Optional)
No automation is provided as removal or updating requires careful consideration of dependencies.
5. Verification / Validation
Confirm the fix by verifying that the application is no longer accessible or has been updated to a secure version.
- Post-fix check: Access the default OFBiz URL (http://{target_ip}:8080) in a web browser. A 404 error or other non-responsive status indicates successful removal.
- Re-test: Re-run the curl command from the detection section; it should not return an OFBiz response.
curl -I http://{target_ip}:80806. Preventive Measures and Monitoring
- Baselines: Include Apache OFBiz in your security baseline if it is a permitted application, with requirements for regular patching.
- Pipelines: Integrate vulnerability scanning into your CI/CD pipeline to detect new installations of vulnerable applications.
7. Risks, Side Effects, and Roll Back
- Risk or side effect 1: Removing OFBiz may disrupt business processes if it is a critical application.
- Roll back: Restore the server from the pre-change backup if removal causes issues.
