Details
There is a possible regular expression based DoS vulnerability in Action Dispatch. This vulnerability has been assigned the CVE identifier CVE-2023-22792. Versions Affected: >= 3.0.0 Not affected: < 3.0.0 Fixed Versions: 5.2.8.15 (Rails LTS), 6.1.7.1, 7.0.4.1 # Impact Specially crafted cookies, in combination with a specially crafted X_FORWARDED_HOST header can cause the regular expression engine to enter a state of catastrophic backtracking. This can cause the process to use large amounts of CPU and memory, leading to a possible DoS vulnerability All users running an affected release should either upgrade or use one of the workarounds immediately. # Workarounds We recommend that all users upgrade to one of the FIXED versions. In the meantime, users can mitigate this vulnerability by using a load balancer or other device to filter out malicious X_FORWARDED_HOST headers before they reach the application.
