CVE-2026-105105 – Unauthenticated ZeroMQ command/telemetry bus in AIT-Core allows remote spacecraft command injection and telemetry exfiltration

1. IMMEDIATE ACTIONS

Upon detection or suspicion of this vulnerability, or if the affected component is identified within your environment, perform the following immediate actions to contain and mitigate potential exploitation:

a. Isolate Affected Systems: Immediately disconnect or segment any systems identified as running the vulnerable component from external networks. If full disconnection is not feasible, apply strict firewall rules to block all non-essential inbound and outbound traffic to and from these systems. Prioritize blocking traffic from untrusted external sources.

b. Service Suspension: Temporarily disable or shut down the specific web application or service utilizing the vulnerable component. If the service is critical and cannot be immediately shut down, proceed with extreme caution and implement all other immediate mitigations.

c. Backup Critical Data: Perform an immediate backup of all critical data and configurations on affected systems. Ensure these backups are stored securely and are isolated from the potentially compromised environment.

d. Forensics and Incident Response Activation: Engage your incident response team. Begin collecting forensic data (e.g., memory dumps, disk images, network traffic captures, process listings, log files) from potentially compromised systems before any changes are made. This is crucial for understanding the scope of a breach.

e. Credential Reset: If there is any indication of compromise, assume that credentials associated with the affected application or system accounts may have been stolen. Initiate a mandatory password reset for all service accounts, administrative accounts, and user accounts that interact with the vulnerable application or system.

2. PATCH AND UPDATE INFORMATION

Since this CVE ID is future-dated and no official patch information is available, the following guidance outlines the process to follow once a patch is released by the vendor.

a. Monitor Vendor Advisories: Regularly check the official security advisories and release notes from the vendor of the affected web application framework or component. Subscribe to their security mailing lists or RSS feeds for timely notifications regarding CVE-2026-105105.

b. Obtain Official Patches: Once available, download patches only from official vendor sources. Verify the integrity and authenticity of the downloaded patch using provided checksums (e.g., SHA256) or digital signatures.

c. Test Patches in Staging: Before deploying patches to production environments, rigorously test them in a non-production, representative staging environment. This testing should confirm that the patch resolves the vulnerability without introducing regressions or new issues to the application's functionality.

d. Scheduled Deployment: Plan a controlled deployment window for applying the patch to production systems. Ensure appropriate change management procedures are followed, including communication with stakeholders and a rollback plan in case of unexpected issues.

e. Post-Patch Verification: After applying the patch, verify its successful installation and confirm that the vulnerability is no longer present. This can involve re-running vulnerability scans or specific proof-of-concept checks (if safely available and authorized).

3. MITIGATION STRATEGIES

If immediate patching is not feasible, or as a layered defense, implement the following mitigation strategies to reduce the risk of exploitation for CVE-2026-105105.

a. Web Application Firewall (WAF) Rules: Deploy or update WAF rules to detect and block known exploitation attempts. This may involve creating custom rules to identify specific attack patterns, unusual request parameters, or suspicious payloads targeting the assumed RCE vulnerability (e.g., deserialization gadgets, command injection attempts).

b. Network Segmentation and Least Privilege: Enforce strict network segmentation to limit the attack surface. Ensure the vulnerable component and its host system can only communicate with necessary internal services. Apply the principle of least privilege to the web application's service account, ensuring it runs with the minimum necessary permissions to function, thereby limiting the impact of successful code execution.

c. Input Validation and Sanitization: Implement robust input validation and sanitization at the application layer for all user-supplied data, especially for parameters that interact with the potentially vulnerable component. This should include strict allow-listing of expected input formats and rejection of malformed or unexpected data.

d. Disable Unused Features: If the vulnerable component or a specific feature within it is not critical for the application's operation, disable it. Consult vendor documentation for safe methods to disable components or features.

e. Restrict Outbound Connectivity: Implement firewall rules to restrict outbound connections from the web server to only essential destinations. This can help prevent an attacker from downloading additional tools or exfiltrating data if the server is compromised.

4. DETECTION METHODS

Proactive and reactive detection methods are crucial for identifying the presence of the vulnerability, attempted exploitation, or successful compromise.

a. Vulnerability Scanning: Conduct regular, authenticated vulnerability
