Not all security vulnerabilities pose a high risk on their own, but in the hands of skilled attackers, even minor weaknesses can escalate into significant breaches. This article highlights five real vulnerabilities identified by Intruder’s bug-hunting team, illustrating how attackers exploit overlooked flaws to create serious security incidents.

1. Compromising AWS Credentials via Redirects
   Server-Side Request Forgery (SSRF) is a prevalent vulnerability that can have severe consequences, particularly in cloud environments. If a web application retrieves resources from user-provided URLs, it’s crucial to prevent attackers from manipulating requests to access unauthorized resources. During our evaluation of a home-moving application hosted on AWS, our team explored common SSRF bypass techniques. The attack unfolded as follows: the application sent a webhook request to the attacker’s server, which responded with a 302 redirect to AWS’s metadata service. The application followed the redirect and logged the response, inadvertently exposing sensitive metadata…
