AI-suggested
- Monitor IBM’s official channels for patches addressing CVE-2025-36066 and apply them promptly once available.
- Implement strict input validation and sanitization on all user inputs within the Sterling Connect:Express web interface to prevent injection of malicious scripts.
- Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in the web UI.
- Conduct regular security assessments and penetration testing focused on web interface vulnerabilities.
- Educate users about the risks of interacting with suspicious links or inputs that could trigger XSS attacks.
- Use web application firewalls (WAFs) configured to detect and block XSS attack patterns targeting the Sterling Connect:Express interface.
- Limit access to the web UI to trusted networks or VPNs to reduce exposure to unauthenticated attackers.
- Monitor logs for unusual activity or repeated attempts to inject scripts, enabling early detection of exploitation attempts.
