Synopsis ========
A vulnerability in Active Record could allow a remote attacker to inject SQL commands.
Background ==========
Active Record is a Ruby gem that allows database entries to be manipulated as objects.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-ruby/activerecord < 2.3.14-r1 >= 2.3.14-r1
Description ===========
An Active Record method parameter can mistakenly be used as a scope.
Impact ======
A remote attacker could use specially crafted input to execute arbitrary SQL statements.
Workaround ==========
The vulnerability may be mitigated by converting the input to an expected value. This is accomplished by changing instances of 'Post.find_by_id(params[:id])' in code using Active Record to 'Post.find_by_id(params[:id].to_s)'
Resolution ==========
All Active Record users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot -v ">=dev-ruby/activerecord-2.3.14-r1"
