1. Introduction
Cisco Unified MeetingPlace Detection identifies instances of Cisco Unified MeetingPlace web conferencing software hosted on remote web servers. This is a common application used for virtual meetings and collaboration, but its presence can indicate potential exposure to known vulnerabilities if not properly maintained. A successful exploit could compromise the confidentiality, integrity, and availability of the server and associated data.
2. Technical Explanation
The vulnerability lies in the detection of Cisco Unified MeetingPlace software running on a web server. While not an active exploit *per se*, its presence signals a potential risk requiring investigation and patching. Attackers could target known vulnerabilities within the application itself, or use it as a foothold for further attacks on the network. There is no specific CVE associated with this detection; it’s a signal of potentially outdated software. An attacker might attempt to exploit vulnerabilities in older versions of MeetingPlace to gain unauthorized access to the server and its data.
- Root cause: The presence of Cisco Unified MeetingPlace indicates an application that may have unpatched security flaws.
- Exploit mechanism: Attackers would scan for exposed instances of MeetingPlace, identify the version, and attempt to exploit known vulnerabilities using publicly available tools or custom exploits.
- Scope: Affected platforms are web servers running Cisco Unified MeetingPlace software. Specific versions need to be determined during assessment.
3. Detection and Assessment
Confirming a system is vulnerable involves identifying the presence of Cisco Unified MeetingPlace and its version. A quick check can determine if the application is hosted on the server, while thorough scanning will provide more detailed information.
- Quick checks: Access the web server in a browser and look for branding or login pages associated with Cisco Unified MeetingPlace.
- Scanning: Nessus vulnerability scanner ID 6c20bf30 can identify instances of Cisco Unified MeetingPlace. This is an example only, other scanners may also provide detection.
- Logs and evidence: Web server logs might contain references to MeetingPlace files or directories. Look for paths like /meetingplace or similar.

# No specific command exists for this detection; rely on web access or scanning tools.
4. Solution / Remediation Steps
Fixing the issue involves assessing the need for Cisco Unified MeetingPlace and applying appropriate security measures, including patching or removal.
4.1 Preparation
- Services to stop: Stop the web server service if performing maintenance or updates. A rollback plan involves restoring from the backup.
4.2 Implementation
- Step 1: Determine if Cisco Unified MeetingPlace is still needed by the business. If not, uninstall the application.
- Step 2: If the application is required, identify the current version of Cisco Unified MeetingPlace.
- Step 3: Check for available security patches from Cisco’s official website.
- Step 4: Download and install any applicable security patches following Cisco’s instructions.
4.3 Config or Code Example
Before
# No specific config example; this is about application presence, not configuration.
After
# After: Application either removed or updated to latest patched version.
4.4 Security Practices Relevant to This Vulnerability
Several security practices can help prevent this issue. Least privilege limits the impact of a potential compromise, while patch cadence ensures timely updates.
- Practice 1: Implement least privilege access controls on the web server to reduce the attack surface.
- Practice 2: Establish a regular patch cadence for all software, including web conferencing applications like Cisco Unified MeetingPlace.
4.5 Automation (Optional)
No specific automation is recommended for this detection; it’s primarily an assessment and remediation task.
# No script provided as the fix involves application removal or patching, not automated configuration changes.
5. Verification / Validation
Confirming the fix involves verifying that Cisco Unified MeetingPlace is either removed or updated to a patched version. A smoke test ensures basic web server functionality remains intact.
- Post-fix check: Access the web server in a browser; if the application was removed, it should no longer be accessible. If patched, verify the new version number through the application’s interface.
- Re-test: Re-run the Nessus scan (ID 6c20bf30) to confirm the vulnerability is no longer detected.
- Smoke test: Verify basic web server functionality by accessing other hosted websites or applications.
# Post-fix command and expected output:
# Accessing the webserver URL should not return a Cisco Unified MeetingPlace login page if removed.
6. Preventive Measures and Monitoring
Update security baselines to include regular checks for outdated software, including web conferencing applications. Implement CI/CD pipeline checks to prevent deployment of vulnerable versions.
- Baselines: Update a security baseline or policy to require regular vulnerability scans and patching of all installed software.
- Asset and patch process: Implement a sensible patch review cycle (e.g., monthly) that includes security updates for web conferencing applications.
7. Risks, Side Effects, and Roll Back
- Risk or side effect 1: Removing the application could interrupt ongoing meetings if no alternative is available.
- Risk or side effect 2: Patching might cause temporary service downtime during installation and configuration.
