CVE-2016-6317 (opens in a new tab)How to fix?
Upgrade Debian:11 rails to version 2:4.2.7.1-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream rails package and not the rails package as distributed by Debian.
See How to fix? for Debian:11 relevant fixed versions and status.
Action Record in Ruby on Rails 4.2.x before 4.2.7.1 does not properly consider differences in parameter handling between the Active Record component and the JSON implementation, which allows remote attackers to bypass intended database-query restrictions and perform NULL checks or trigger missing WHERE clauses via a crafted request, as demonstrated by certain "[nil]" values, a related issue to CVE-2012-2660, CVE-2012-2694, and CVE-2013-0155.
