Same-origin script execution via CRLF response injection
Published Oct 23, 2025 · Updated Oct 23, 2025
CRLF injection in KeeneticOS before 4.3 allows remote attackers to execute script in a router administrator's browser via a crafted /auth URL. The /auth handler copies the unfiltered url parameter into the Location response header, so encoded newlines inject headers and an HTML body in the router's origin. Exploitation requires an authorized administrator to open the crafted link, after which the script can perform privileged management actions through that session.
