How Breaches Start: Breaking Down 5 Real Vulns
Apr 28, 2025Cloud Security / Vulnerability
Not every security vulnerability is high risk on its own - but in the hands of an advanced attacker, even small weaknesses can escalate into major breaches. These five real vulnerabilities, uncovered by Intruder's bug-hunting team, reveal how attackers turn overlooked flaws into serious security incidents. 1. Stealing AWS Credentials with a Redirect Server-Side Request Forgery (SSRF) is a common vulnerability that can have a significant impact, especially in cloud-hosted applications. If a web application fetches resources from user-supplied URLs, care should be taken to ensure attackers can't manipulate requests to access unintended resources. While assessing a home-moving app running in AWS, our team tested common SSRF bypass techniques. The attack chain was as follows: the app sent a webhook request to the attacker's web server, which responded with a 302 redirect to AWS's metadata service. The app followed the redirect and logged the response, which exposed sensitive metadat...
