Severity:	normal
Title:	Ruby on Rails: Multiple vulnerabilities
Date:	11/14/2007
Bugs:	#195315, #182223
ID:	200711-17

Synopsis

Several vulnerabilities were found in Ruby on Rails allowing for file disclosure and theft of user credentials.

Background

Ruby on Rails is a free web framework used to develop database-driven web applications.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
dev-ruby/rails	< 1.2.5	>= 1.2.5	All supported architectures

Description

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.

Resolution

All Ruby on Rails users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-ruby/rails-1.2.5"
