CVE-2013-0156 NOMISEC WORKING POC
Ruby on Rails JSON Processor YAML Deserialization Code Execution
active_support/core_ext/hash/conversions.rb in Ruby on Rails before 2.3.15, 3.0.x before 3.0.19, 3.1.x before 3.1.10, and 3.2.x before 3.2.11 does not properly restrict casts of string values, which allows remote attackers to conduct object-injection attacks and execute arbitrary code, or cause a denial of service (memory and CPU consumption) involving nested XML entity references, by leveraging Action Pack support for (1) YAML type conversion or (2) Symbol type conversion.

CVE-2012-2125 WRITEUP WRITEUP
RubyGems < 1.8.23 - HTTPS to HTTP Redirection
RubyGems before 1.8.23 can redirect HTTPS connections to HTTP, which makes it easier for remote attackers to observe or modify a gem during installation via a man-in-the-middle attack.
CVE-2012-2126 WRITEUP WRITEUP
RubyGems < 1.8.23 - Man-in-the-Middle Attack via Unverified SSL Certificate
RubyGems before 1.8.23 does not verify an SSL certificate, which allows remote attackers to modify a gem during installation via a man-in-the-middle attack.
