CVE-2019-17513

An issue was discovered in Ratpack before 1.7.5. Due to a misuse of the Netty library class DefaultHttpHeaders, there is no validation that headers lack HTTP control characters. Thus, if untrusted data is used to construct HTTP headers with Ratpack, HTTP Response Splitting can occur...

CVE-2019-17513

CVE-2019-17513 affects Ratpack before 1.7.5. The root cause is misuse of Netty’s DefaultHttpHeaders with validation disabled, allowing untrusted input used in HTTP headers to cause HTTP Response Splitting (CRLF injection). Upgrading Ratpack to 1.7.5 (or later) patches the issue by restoring heade...

HTTP Response Splitting

Overview io.ratpack:ratpack-core is a simple, capable, toolkit for creating high performance web applications. Affected versions of this package are vulnerable to HTTP Response Splitting. If untrusted and unsanitized data is used to populate the headers of an HTTP response, an attacker can utiliz...

Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) in Ratpack

Ratpack versions before 1.6.1 generate a session ID using a cryptographically weak PRNG in the JDK's ThreadLocalRandom. This means that if an attacker can determine a small window for the server start time and obtain a session ID value, they can theoretically determine the sequence of session IDs...

CVE-2019-11808

CVE-2019-11808 affects Ratpack versions before 1.6.1, where session IDs are generated using a cryptographically weak PRNG in the JDK’s ThreadLocalRandom. The consequence is that if an attacker can narrow the server-start window and observe a session ID, they could theoretically determine the sequ...
