activesupport in Rails vulnerable to incorrect data conversion (GHSA-xgr2-v94m-rc9g)
Published: 2017-10-24T18:33:37Z
Aliases: CVE-2013-0333
Severity: HIGH · CWE: CWE-74

`lib/active_support/json/backends/yaml.rb` in Ruby on Rails 2.3.x before 2.3.16 and 3.0.x before 3.0.20 does not properly convert JSON data to YAML data for processing by a YAML parser, which allows remote attackers to execute arbitrary code, conduct SQL injection attacks, or bypass authentication via crafted data that triggers unsafe decoding, a different vulnerability than CVE-2013-0156.
