Description

CVE-2015-7577

activerecord/lib/active_record/nested_attributes.rb in Active Record does not properly implement a certain destroy option, which allows remote attackers to bypass intended change restrictions by leveraging use of the nested attributes feature.

For Debian 7 'Wheezy', this problem have been fixed in version 3.2.6-5+deb7u2.

We recommend that you upgrade your ruby-activerecord-3.2 packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
