The remote host is affected by the vulnerability described in GLSA-200912-02 (Ruby on Rails: Multiple vulnerabilities)

    The following vulnerabilities were discovered:
    sameer     reported that lib/action_controller/cgi_process.rb removes the     :cookie_only attribute from the default session options     (CVE-2007-6077), due to an incomplete fix for CVE-2007-5380 (GLSA     200711-17).
    Tobias Schlottke reported that the :limit and     :offset parameters of ActiveRecord::Base.find() are not properly     sanitized before being processed (CVE-2008-4094).
    Steve from     Coderrr reported that the CRSF protection in protect_from_forgery()     does not parse the text/plain MIME format (CVE-2008-7248).
    Nate reported a documentation error that leads to the assumption     that a block returning nil passed to     authenticate_or_request_with_http_digest() would deny access to the     requested resource (CVE-2009-2422).
    Brian Mastenbrook reported     an input sanitation flaw, related to multibyte characters     (CVE-2009-3009).
    Gabe da Silveira reported an input sanitation     flaw in the strip_tags() function (CVE-2009-4214).
    Coda Hale     reported an information disclosure vulnerability related to HMAC     digests (CVE-2009-3086).
  Impact :

    A remote attacker could send specially crafted requests to a vulnerable     application, possibly leading to the execution of arbitrary SQL     statements or a circumvention of access control. A remote attacker     could also conduct session fixation attacks to hijack a user's session     or bypass the CSRF protection mechanism, or furthermore conduct     Cross-Site Scripting attacks or forge a digest via multiple attempts.
  Workaround :

    There is no known workaround at this time.

The remote host is running a version of Mac OS X 10.5 or 10.4 that does not have Security Update 2007-009 applied. 

This update contains several security fixes for a large number of programs.

リモートホスト上の Web サーバーは、URL ベースのセッションをサポートするバージョンの Ruby on Rails のようです。認証されていないリモート攻撃者は、この問題を利用して、認証されたセッションを得ることができる場合があります。 

Ruby on Rails バージョン 1.2.4 は、当初この問題に対処すると考えられていましたが、そのセッション固定ロジックは、CgiRequest が最初にインスタンス化される場合に、最初のリクエストに対してのみ機能することに注意してください。

Rails core team reports :

The rails core team has released ruby on rails 1.2.6 to address a bug in the fix for session fixation attacks (CVE-2007-5380). The CVE Identifier for this new issue is CVE-2007-6077.

The web server on the remote host appears to be a version of Ruby on Rails that supports URL-based sessions.  An unauthenticated, remote attacker may be able to leverage this issue to obtain an authenticated session. 

Note that Ruby on Rails version 1.2.4 was initially supposed to address this issue, but its session fixation logic only works for the first request, when CgiRequest is first instantiated.

远程主机上的 Web 服务器似乎为支持基于 URL 的会话的 Ruby on Rails 版本。未经身份验证的远程攻击者可能会利用此问题获取经身份验证的会话。 

请注意，起初认为 Ruby on Rails 版本 1.2.4 会解决此问题，但在首先实例化 CgiRequest 时，其会话固定逻辑仅对第一个请求起作用。

遠端主機上的 web 伺服器似乎是支援 URL 型工作階段的 Ruby on Rails 版本。未經驗證的遠端攻擊者可以利用此問題取得經過驗證的工作階段。 

請注意，Ruby on Rails 版本 1.2.4 原先應要解決此問題，但其工作階段固定邏輯只能在 CgiRequest 首度具現化時用於第一個要求。

The remote server is running the Ruby on Rails web application.
This version of Rails is reported to be vulnerable to a flaw in the way that it handles authentication data.  Allegedly, the 'lib/action_controller/cgi_process.rb' script is vulnerable to a flaw that would allow an attacker to steal cookie data.  An attacker could then use this data to gain access to the application with the user's credentials.
