1. Introduction
EMC RSA Archer is a network governance, risk, and compliance platform running on remote web servers. It’s used by businesses to manage their GRC programs. A vulnerable instance could allow an attacker to gain access to sensitive data within the system. This vulnerability has a likely impact of high confidentiality loss, medium integrity compromise, and low availability disruption.
2. Technical Explanation
EMC RSA Archer is running on the remote host, indicating potential exposure through its web interface. While specific details aren’t provided, this suggests an attacker could attempt to exploit known vulnerabilities within the Archer WebUI. Preconditions involve network access to the server hosting the application and a functioning web browser. An attacker might leverage default credentials or known exploits to gain unauthorized access.
- Root cause: The presence of the RSA Archer WebUI indicates the service is exposed, potentially with unpatched vulnerabilities.
- Exploit mechanism: An attacker could attempt to exploit weaknesses in the WebUI through techniques like cross-site scripting (XSS), SQL injection or authentication bypass.
- Scope: Affected platforms are servers running EMC RSA Archer. Specific versions aren’t identified in this context.
3. Detection and Assessment
To confirm vulnerability, first check for the presence of the application. A thorough method involves reviewing the application version.
- Quick checks: Use a web browser to access the server’s IP address or hostname on standard HTTP/HTTPS ports (80/443).
- Scanning: Nessus vulnerability scan ID 727fe3c can identify instances of EMC RSA Archer. This is an example only.
- Logs and evidence: Review web server logs for requests to the Archer WebUI application path. Exact paths are not specified in this context.

# No specific command available without knowing the Archer installation directory. Check web server configuration files.
4. Solution / Remediation Steps
The following steps outline how to address a potential vulnerability with EMC RSA Archer.
4.1 Preparation
- Services: No services need to be stopped for this assessment, but plan downtime if patching is required.
- Dependencies: Ensure you have access to the latest RSA Archer documentation and patches. A roll back plan involves restoring from the pre-change backup.
4.2 Implementation
- Step 1: Review the current version of EMC RSA Archer installed on the system.
- Step 2: Check for available security patches from EMC/Dell support website.
- Step 3: Download and install any applicable security patches following vendor instructions.
4.3 Config or Code Example
Before
# No specific configuration example available without knowing the Archer installation details. After
# Verify the installed patch version after applying updates. Check application logs for successful patching. 4.4 Security Practices Relevant to This Vulnerability
Several security practices can help prevent this issue.
- Practice 1: Patch cadence: Regularly apply security patches from the vendor to address known vulnerabilities.
- Practice 2: Least privilege: Ensure users have only the necessary permissions to perform their tasks, reducing potential impact if accounts are compromised.
4.5 Automation (Optional)
No automation steps are provided due to lack of specific context.
# No suitable script available without knowing the Archer installation details and environment. 5. Verification / Validation
Confirm the fix by verifying the patch version and performing a smoke test.
- Post-fix check: Check the application version to confirm the latest security patch is installed.
- Re-test: Re-run the Nessus scan (ID 727fe3c) to verify the vulnerability is no longer detected.
- Smoke test: Verify users can log in and access key functionality within EMC RSA Archer.
# Example command placeholder:
# No specific command available without knowing the Archer installation directory. Check web server configuration files.
6. Preventive Measures and Monitoring
Implement preventive measures to reduce future risk.
- Baselines: Update security baselines or policies to include regular patch management for EMC RSA Archer.
- Pipelines: Integrate vulnerability scanning into CI/CD pipelines to identify potential issues early in the development lifecycle.
- Asset and patch process: Establish a defined patch review cycle based on risk assessment.
7. Risks, Side Effects, and Roll Back
Consider risks associated with patching.
- Risk or side effect 1: Patching may cause temporary service disruption. Mitigate by scheduling during off-peak hours.
- Risk or side effect 2: Incompatibility issues with other applications. Mitigate through testing in a non-production environment.
- Roll back: Restore the system from the pre-change backup if patching causes unexpected issues.
