Padding Oracle Vulnerability in Ruby on Rails 2.3 by Ruby

CVE-2010-3299

What is CVE-2010-3299?

The Ruby on Rails framework version 2.3 contains a vulnerability in its encrypt and decrypt functions, which can be exploited through padding oracle attacks. This type of attack allows an adversary to decrypt sensitive information by making a series of requests and analyzing the padding error responses returned by the application. As a result, attackers can potentially obtain access to protected data without needing to know the encryption key, posing significant risks to applications built on this framework. Developers using affected versions are advised to upgrade to newer, secure versions to mitigate this risk.
