Exploiting SSTI in a Modern Spring Boot Application (3.3.4)

👤 by parzel

The article explores exploiting a Server-Side Template Injection (SSTI) vulnerability in a Spring Boot 3.3.4 application using Thymeleaf, leading to Remote Code Execution (RCE). It highlights the process of injecting malicious input to trigger Java reflection and bypass security defenses in modern framework.

The post provides a detailed walkthrough of achieving RCE despite the robust safeguards present, emphasizing the complexity of exploiting such vulnerabilities in contemporary applications.

Next.js and the corrupt middleware: the authorizing artifact

👤 by Rachid Allam & Yasser Allam

Researchers have discovered a critical vulnerability in Next.js, a popular framework for building web applications. The flaw allows attackers to bypass middleware responsible for request processing, including authentication and path rewrites.

By adding the x-middleware-subrequest header with a specific value, an attacker can completely ignore middleware execution, gaining unauthorized access to protected resources. Additionally, the vulnerability can be exploited for denial-of-service (DoS) attacks by poisoning the cache, leading to service disruption.

Many versions of Next.js are affected, making this a widespread security concern.

📝 Contents:
● The Next.js middleware
● The authorizing artifact artifact: old code, 0ld treasure
• Execution order and middlewareInfo.name
● The authorizing artifact: nostalgia has its charm, but living in the moment is better
• /src directory
• Max recursion depth
● Exploits
• Authorization/Rewrite bypass
• CSP bypass
• DoS via Cache-Poisoning (what?)
• Clarification
● Security Advisory - CVE-2025-29927
● Disclaimer
● Conclusion

Don't Call That "Protected" Method: Dissecting an N-Day vBulletin RCE

👤 by Egidio Romano

The article analyzes a critical Unauthenticated Remote Code Execution vulnerability (CVE-2025-48827) in vBulletin, which becomes exploitable when running on PHP 8.1 or newer.

The vulnerability stems from vBulletin’s misuse of ReflectionMethod::invoke(), which in PHP 8.1+ no longer blocks access to protected methods by default. As a result, attackers can remotely trigger sensitive internal functions originally meant to be inaccessible and achieve code execution on the server.
