An unauthenticated, remote attacker can exploit these flaws to trigger a denial-of-service (DoS) condition, manipulate sensitive data, and facilitate subsequent attacks, including cache poisoning and session hijacking. The vulnerabilities exist in the Undertow component. While specific CVEs are not listed in the advisory, the impact could be significant, leading to service disruption and potential data compromise.
