This blog post is a collaborative effort by three security researchers who discovered a novel HTTP Request Smuggling vulnerability, dubbed "TE.0". They found that thousands of Google Cloud-hosted websites using the Load Balancer were vulnerable to this attack, which could compromise sensitive data and resources. The researchers used their own tool, bbscope, to scan for vulnerable targets, and after experimenting with different payloads, they discovered a new smuggling class that could bypass Google IAP authentication and Zero Trust security measures. They reported the issue to Google, initially being met with skepticism, but eventually receiving recognition and a $8,500 bounty. The researchers emphasize the importance of persistence and creative thinking in uncovering vulnerabilities and encourage others to explore their interests deeply.
