Mikal Gule discovered that request-tracker, an extensible trouble-ticket tracking system, is prone to an attack, where an attacker with access to the same domain can hijack a user's RT session.

The version of Best Practical Solutions Request Tracker (RT) running on the remote web server is affected by a session fixation vulnerability due to the application authenticating users without invalidating their existing session ID. A remote attacker can exploit this by tricking a user into logging in with a known session ID, allowing the attacker to hijack the user's session.

This version of RT is reportedly affected by a different session fixation vulnerability, though Nessus has not checked for it.

Mikal Gule 氏は、拡張可能なトラブルチケットトラッキングシステムである request-tracker が、同じドメインにアクセスできる攻撃者がユーザーの RT セッションをハイジャックする可能性がある攻撃に対して脆弱であることを発見しました。

リモートWebサーバーで実行されているBest Practical Solutions Request Tracker（RT）のバージョンは、既存のセッションIDを無効にすることなくユーザーを認証するアプリケーションが原因で、セッションフィクセーションの脆弱性の影響を受けます。リモート攻撃者が、これを悪用して、ユーザーを騙して既知のセッションIDでログインさせることで、ユーザーのセッションをハイジャックする可能性があります。

このRTのバージョンは、別のセッションフィクセーションの脆弱性の影響を受けることが報告されていますが、Nessusではそれを確認していません。

遠端 Web 伺服器上執行的 Best Practical Solutions Request Tracker (RT) 版本受到一個工作階段固定弱點影響，這是因為應用程式未驗證使用者現有的工作階段 ID 就對其進行驗證所致。遠端攻擊者可誘騙使用者以已知的工作階段 ID 登入，藉此惡意利用此弱點，進而允許攻擊者劫持使用者的工作階段。

據報此版本的 RT 受到一個不同的工作階段固定弱點影響，但 Nessus 尚未對此進行檢查。
