Gentoo Linux Security Advisory

Title: Ruby on Rails: Multiple vulnerabilities (GLSA 200711-17)
Severity: normal
Exploitable: remote
Date: November 14, 2007
Bug(s): #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: dev-ruby/rails
Vulnerable: < 1.2.5
Unaffected: >= 1.2.5
Architectures: 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:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-ruby/rails-1.2.5"
