Security Advisories 🚨

🚨 Possible DoS Vulnerability in Active Record PostgreSQL adapter

There is a possible DoS vulnerability in the PostgreSQL adapter in Active
Record. This vulnerability has been assigned the CVE identifier CVE-2021-22880.

Versions Affected: >= 4.2.0
Not affected: < 4.2.0
Fixed Versions: 6.1.2.1, 6.0.3.5, 5.2.4.5

Impact

Carefully crafted input can cause the input validation in the "money" type of
the PostgreSQL adapter in Active Record to spend too much time in a regular
expression, resulting in the potential for a DoS attack.

This only impacts Rails applications that are using PostgreSQL along with
money type columns that take user input.

Workarounds

In the case a patch can't be applied, the following monkey patch can be used
in an initializer:

module ActiveRecord
  module ConnectionAdapters
    module PostgreSQL
      module OID # :nodoc:
        class Money < Type::Decimal # :nodoc:
          def cast_value(value)
            return value unless ::String === value
        value = value.sub(/^\((.+)\)$/, '-\1') # (4)
        case value
        when /^-?\D*+[\d,]+\.\d{2}$/  # (1)
          value.gsub!(/[^-\d.]/, "")
        when /^-?\D*+[\d.]+,\d{2}$/  # (2)
          value.gsub!(/[^-\d,]/, "").sub!(/,/, ".")
        end

        super(value)
      end
    end
  end
end

end

end

Release Notes

5.2.4.5 (from changelog)
