Cross-site Scripting (XSS)

Overview io.ratpack:ratpack-core is a simple, capable, toolkit for creating high performance web applications. Affected versions of this package are vulnerable to Cross-site Scripting XSS. This affects the development mode error handler when an exception message contains untrusted data. Note the...

io.ratpack:ratpack-core vulnerable to Improper Neutralization of Special Elements in Output ('Injection')

CWE-113: Improper Neutralization of CRLF Sequences in HTTP Headers 'HTTP Response Splitting' Versions of Ratpack 0.9.1 through and including 1.7.4 are vulnerable to HTTP Response Splitting, if untrusted and unsanitized data is used to populate the headers of an HTTP response. An attacker can...

GHSA-MVQP-Q37C-WF9J io.ratpack:ratpack-core vulnerable to Improper Neutralization of Special Elements in Output ('Injection')

CWE-113: Improper Neutralization of CRLF Sequences in HTTP Headers 'HTTP Response Splitting' Versions of Ratpack 0.9.1 through and including 1.7.4 are vulnerable to HTTP Response Splitting, if untrusted and unsanitized data is used to populate the headers of an HTTP response. An attacker can...

HTTP Response Splitting

ratpack-core is vulnerable to HTTP response splitting. The vulnerability exists due to the lack of validation of response header values as the DefaultHttpHeaders object is created with verification disabled by default, allowing malicious user-supplied values to be part of response headers...

Ratpack Input Validation Error Vulnerability

Ratpack is a Java library for building scalable HTTP applications. An input validation error vulnerability exists in Ratpack versions prior to 1.7.5, which can be exploited to conduct http response splitting attacks by constructing HTTP headers with untrusted data...

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...

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...
