CVE-2025-0697Public exploitNetwork attack vector

Response header injection via unsanitized request path

Published Jan 24, 2025 · Updated Feb 12, 2025

HTTP response header injection in Telstra Smart Modem Gen 2 version 20250115 allows remote attackers to alter server responses. The HTTP header handler copies the URL path after /robots.txt into Content-Disposition without neutralizing percent-encoded CRLF sequences. No authentication is required, and a crafted GET permits arbitrary response headers or an attacker-controlled response body; published impact is limited to response integrity.
