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.

Malicious users could specify their session-ID in the URL and could gain access to an authenticated session that way (CVE-2007-5380).

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.

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 affected by the vulnerability described in GLSA-200711-17 (Ruby on Rails: Multiple vulnerabilities)

    candlerb found that ActiveResource, when processing responses using the     Hash.from_xml() function, does not properly sanitize filenames     (CVE-2007-5380). The session management functionality allowed the     'session_id' to be set in the URL (CVE-2007-5380). BCC discovered that     the to_json() function does not properly sanitize input before     returning it to the user (CVE-2007-3227).
  Impact :

    Unauthenticated remote attackers could exploit these vulnerabilities to     determine the existence of files or to read the contents of arbitrary     XML files; conduct session fixation attacks and gain unauthorized     access; and to execute arbitrary HTML and script code in a user's     browser session in context of an affected site by enticing a user to     browse a specially crafted URL.
  Workaround :

    There is no known workaround at this time.

The remote server is running the Ruby on Rails web application.
This version of Rails is reported to be vulnerable to a number of flaws.  It is reported that a remote attacker can perform man-in-the-middle attacks and gain user credentials.  It is also reported that there is a content-parsing flaw in the XML handler that would allow an attacker to either gain unauthorized access to data or cause the application to fail.
