mikecao/flight PHP framework | Versions prior to v1.2
How the Exploit Works
The exploit leverages the eager loading of request bodies in the Request class constructor of the mikecao/flight PHP framework. This framework automatically reads the entire request body on every HTTP request, irrespective of whether the application requires it. The vulnerability can be exploited by sending requests with large payloads, leading to excessive memory consumption. This can ultimately exhaust server memory, causing application crashes or service unavailability.
Conceptual Example Code
Here is a conceptual example of how the vulnerability might be exploited. An attacker could send a large payload to a vulnerable endpoint, like so:
POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
Content-Length: 999999999
{ "large_payload": "<payload data>" }In this example, `
Mitigation Guidance
To mitigate the risk of this vulnerability, users are advised to use the vendor’s patch by upgrading to mikecao/flight PHP framework version 1.2 or later. If upgrading is not immediately possible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation against potential attacks exploiting this vulnerability.
