Cookie Security: Overly Broad Session Cookie Path

Java/JSP
PHP

Abstract

透過共用同一個網域的應用程式，會洩漏路徑範圍過大的階段作業 Cookie。

Explanation

開發人員通常會將階段作業 Cookie 設為根內容路徑 ("/")。這會將 Cookie 揭露給同一個網域名稱的所有 Web 應用程式。洩漏階段作業 Cookie 會造成帳戶洩漏，因為攻擊者可能使用網域中任一個應用程式的弱點來竊取階段作業 Cookie。

範例 1：想像您已在 http://communitypages.example.com/MyForum 部署論壇應用程式，且當使用者登入論壇時，應用程式以路徑「/」設定工作階段 cookie。例如：


server.servlet.session.cookie.path=/

假設攻擊者在 http://communitypages.example.com/EvilSite 建立另一個應用程式，並在此論壇中張貼連至此網站的連結。當該論壇的使用者按一下此連結時，其瀏覽器會將 /MyForum 設定的 Cookie 傳送到在 /EvilSite 執行的應用程式。透過使用使用者在 /MyForum 上提供的階段作業 Cookie，攻擊者可對瀏覽到 /EvilSite 的任何論壇使用者帳戶造成危害。

開發人員通常會將階段作業 Cookie 設為根內容路徑 (「/」)。這麼做會將 Cookie 揭露給同一個網域名稱的所有 Web 應用程式。洩漏階段作業 Cookie 會造成帳戶洩漏，因為攻擊者可能使用網域中任一個應用程式的弱點來竊取階段作業 Cookie。

例如：


session_set_cookie_params(0, "/", "communitypages.example.com", true, true);

假設攻擊者在 http://communitypages.example.com/EvilSite建立另一個應用程式，並在此論壇中張貼連至此網站的連結。當該論壇的使用者按一下此連結時，該使用者的瀏覽器會將由 /MyForum 設定的階段作業 Cookie 傳送到在 /EvilSite 執行的應用程式。透過竊取階段作業 Cookie，攻擊者便可危及瀏覽 /EvilSite 的任何論壇使用者之帳戶安全。
