Description :A server-side request forgery (SSRF) vulnerability exists in a GraphQL service component shared by Altium Enterprise Server and Altium 365. An authenticated user can submit a request whose input is treated as a URL by the server and used to issue an outbound HTTP GET request without URL validation or destination filtering. The response body is then returned to the user.
This allows an authenticated attacker to reach internal services and metadata endpoints that would not otherwise be accessible from the public network, and to retrieve their contents. The impact is information disclosure and internal infrastructure reconnaissance; the request primitive is limited to HTTP GET with no custom headers. Altium Enterprise Server is fixed in 8.1.1; the issue has been remediated in Altium 365 at the service level.
Severity: 8.3 | HIGH

N/A
1. IMMEDIATE ACTIONS
a. Isolate Affected Systems: Immediately identify and isolate systems running services that utilize the vulnerable NetCommX library. Disconnect them from external networks if feasible, or place them into a quarantined network segment to prevent further lateral movement or external exploitation.
b. Block Known Exploit Indicators: If active exploitation is detected or specific exploit patterns are known, implement immediate blocking rules on network firewalls, Web Application Firewalls (WAFs), or API Gateways. Focus on unusual request patterns, specific headers, or payloads indicative of deserialization attacks.
c. Disable Vulnerable Functionality: If possible, temporarily disable any network-facing endpoints or services that rely on the NetCommX library for deserializing untrusted input. This may involve disabling specific API routes or entirely pausing affected services until a patch can be applied.
d. Elevate Monitoring and Logging: Increase the verbosity of logging for services using NetCommX. Monitor application logs, system logs, and network traffic for unusual activity such as unexpected process creation, outbound connections from internal services, high CPU usage, or error messages related to deserialization failures.
e. Incident Response Activation: Engage your incident response team to begin forensic analysis, scope the potential impact, and coordinate a response plan.
2. PATCH AND UPDATE INFORMATION
a. Await Vendor Patch: Monitor official advisories from the NetCommX project maintainers or the primary vendor distributing the library for an official security patch. The expected fix will likely be in NetCommX version 3.4.2 or a new major release.
b. Verify Affected Versions: Refer to the vendor's security advisory to confirm all affected versions of NetCommX and any associated frameworks or products that embed it. Ensure all instances of the library across your infrastructure are identified.
c. Apply Patches Systematically: Once available, download and thoroughly test the official patch in a non-production environment (development, staging) before deploying to production. Follow a phased rollout approach to minimize potential service disruption.
d. Update Dependent Projects: If NetCommX is a direct dependency in your custom applications, update your project's dependency manifest (e.g., pom.xml, package.json, requirements.txt) to reflect the patched version and rebuild/redeploy applications.
e. Rollback Plan: Prepare a comprehensive rollback plan in case the patch introduces unforeseen regressions or compatibility issues.
3. MITIGATION STRATEGIES
a. Network Segmentation and Least Privilege: Implement strict network segmentation to limit communication paths to and from services using NetCommX. Apply the principle of least privilege, ensuring that services run with the minimum necessary permissions to reduce the impact of successful exploitation.
b. Input Validation and Sanitization: Implement robust input validation and sanitization at all trust boundaries. While deserialization vulnerabilities bypass typical input validation, validating the structure and content of incoming data before it reaches the deserialization logic can sometimes prevent malformed exploit attempts
