Details
There is a possible regular expression based DoS vulnerability in Action
Dispatch related to the If-None-Match header. This vulnerability has been
assigned the CVE identifier CVE-2023-22795.
Versions Affected: All
Not affected: None
Fixed Versions: 5.2.8.15 (Rails LTS), 6.1.7.1, 7.0.4.1
# Impact
A specially crafted HTTP If-None-Match header can cause the regular
expression engine to enter a state of catastrophic backtracking, when on a
version of Ruby below 3.2.0. 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 If-None-Match headers before they reach
the application.
Users on Ruby 3.2.0 or greater are not affected by this vulnerability.
