Security readout for executives and security teams
Plain-English summary
CVE-2021-38123 is an open redirect issue in Micro Focus Network Automation. Affected systems could send authenticated users to attacker-controlled websites. The main business risk is phishing or credential theft using a trusted Network Automation context, not direct system takeover based on the provided sources.
Executive priority
Treat this as a targeted phishing-enablement issue for affected Network Automation deployments. Prioritize verification and vendor-guided remediation, especially for externally reachable or broadly used administrative portals.
Technical view
The CVE record describes an open redirect after authentication affecting Network Automation versions 10.4x, 10.5x, 2018.05, 2018.11, 2019.05, 2020.02, 2020.08, 2020.11, and 2021.05. No CVSS vector, CWE, exploit proof, or remediation detail is included in the source bundle.
Likely exposure
Exposure is likely limited to organizations running the listed Micro Focus Network Automation versions, especially where users or administrators access the application through browsers. The description indicates the redirect occurs after authentication.
Exploitation context
The provided sources do not show CISA KEV listing or active exploitation. The plausible attack context is social engineering against authenticated users, using a redirect to move them from a trusted application to a malicious website.
Researcher notes
Evidence is thin: the bundle names affected versions and post-authentication open redirect behavior, but lacks CVSS, CWE, patch details, or exploit indicators. Avoid assuming broader product impact beyond Micro Focus Network Automation.
Mitigation direction
- Identify whether any Network Automation instance runs an affected listed version.
- Review the Micro Focus advisory for vendor-approved fixes or workarounds.
- Limit Network Automation access to trusted networks and administrators.
- Train users to verify unexpected redirects after signing in.
Validation and detection
- Inventory Network Automation versions against the affected version list.
- Review authentication workflows for unexpected external redirect behavior.
- Check logs for unusual post-login redirects to external domains.
- Confirm remediation status against official Micro Focus guidance.
