What is CVE-2018-12537?

Eclipse Vert.x versions 3.0 to 3.5.1 contain a vulnerability in which the HttpServer and HttpClient fail to properly filter carriage return and line feed characters from response and request header values. This oversight allows attackers to inject new headers into client requests or server responses, leading to potential security risks such as HTTP response splitting or cache poisoning. Organizations using affected versions should apply the recommended updates to mitigate these risks.

Affected Version(s)

Eclipse Vert.x 3.0

Eclipse Vert.x <= 3.5.1

Exploit Proof of Concept (PoC)
