Two new vulnerabilities (CVE-2013-0156, CVE-2013-0155) have been reported in the Ruby on Rails web framework. CVE-2013-056 is considered a critical vulnerability that should be patched or worked around immediately ("allows attackers to bypass authentication systems, inject arbitrary SQL, inject and execute arbitrary code, or perform a DoS attack on a Rails application"), while CVE-2013-055 can alter some SQL queries when JSON parameter parsing is used. They are different than the SQL injection we reported on January 3. More information on -056 can be found in this analysis.
