    How the Exploit Works

    The exploit takes advantage of an unauthorized backdoor in the source code of myBB version 1.6.4. This backdoor allows attackers to execute arbitrary PHP code remotely by injecting payloads into a specially crafted collapsed cookie. This means that an attacker can manipulate the web server to execute malicious code without any authentication or user interaction. Since the vulnerability was introduced during the packaging process, it is not part of the intended application logic, making it difficult to detect without a thorough source code review.

    Conceptual Example Code

    Below is a conceptual example of how this vulnerability might be exploited. The attacker crafts a malicious payload and injects it into a collapsed cookie sent to the vulnerable server.

    GET / HTTP/1.1
    Host: target.example.com
    Cookie: MYBB[COLLAPSED]=arbitrary_php_code

    In this example, `arbitrary_php_code` would be replaced with the attacker’s malicious PHP code. When the server processes the cookie, it executes the injected PHP code, leading to a potential full system compromise.

    Recommended Mitigations

    As a response to this vulnerability, it is imperative to apply the vendor-supplied patch to remove the backdoor from the source code. If immediate patching is not possible, implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) may serve as a temporary mitigation.
