CVE-2016-2569

안녕하세요, 제 첫 블로그 글을 읽어주셔서 감사합니다. 오늘은 오픈소스 도구인 Squid 캐싱 프록시 서버를 위한 익스플로잇 제작에 대해 알아보겠습니다. 그래서 Squido는 무엇인가? Squid는 HTTP, HTTPS, FTP 등을 지원하는 웹 캐싱 프록시입니다. 자주 요청되는 웹 페이지를 캐싱하고 재사용하여 대역폭을 줄이고 응답 시간을 개선합니다. Squid는 광범위한 접근 제어 기능을 갖추고 있으며 훌륭한 서버 가속기 역할을 합니다. Windows를 포함한 대부분의 사용 가능한 운영 체제에서 실행되며 GNU GPL 라이선...

Netty's CorsHandler.setVaryHeader uses set() to write the Vary: Origin header, which replaces any application-defined Vary headers (e.g., Authorization, Cookie) rather than appending to them. This causes caching proxies and CDNs to ignore per-user cache keys and serve one user's authenticated res...

CVE-2025-71381

A flaw was found in Hono's Cross-Origin Resource Sharing CORS middleware. When the origin is not set to a wildcard, the middleware improperly copies the Vary header from incoming requests into the response. This allows an attacker to inject arbitrary Vary values, potentially leading to cache key...
