QID 982013: Java (maven) Security Update for io.ratpack:ratpack-session (GHSA-2cc5-23r7-vc4v)

Security update has been released for io.ratpack:ratpack-session to fix the vulnerability.

Note: The preceding description block is extracted directly from the security advisory. Using automation, we have attempted to clean and format it as much as possible without introducing additional issues.

The client side session module uses the application startup time as the signing key by default. This means that if an attacker can determine this time, and if encryption is not also used (which is recommended, but is not on by default), the session data could be tampered with by someone with the ability to write cookies.

The default configuration is unsuitable for production use as an application restart renders all sessions invalid and is not multi-host compatible, but its use is not actively prevented.

CVSS V3 rated as Medium - 3.1 severity.

CVSS V2 rated as Medium - 3.5 severity.

Solution

As of Ratpack 1.9.0 the default value is a securely randomly generated value, generated at application startup time.Workaround:
Supply an alternative signing key, as per the documentation's recommendation.
