# CVE-2024-47887: rails: Action Pack is a framework for handling and responding to web requests CVE-2024-47887 is fixed in 15 products on 1 platform, first by rails 2:4.2.10-0ubuntu4+esm1, released October 16, 2024. It is not reported as exploited. Patch Radar priority: Routine. - Web page: https://patchblox.com/security/cve/CVE-2024-47887 - Priority: Routine - CVSS: n/a (Medium) - EPSS: 0.0104 - CISA KEV: not listed - Exploited (vendor report): no - Publicly disclosed: no - Published: Oct 16, 2024 ## Description Action Pack is a framework for handling and responding to web requests. Starting in version 4.0.0 and prior to versions 6.1.7.9, 7.0.8.5, 7.1.4.1, and 7.2.1.1, there is a possible ReDoS vulnerability in Action Controller's HTTP Token authentication. For applications using HTTP Token authentication via `authenticate_or_request_with_http_token` or similar, a carefully crafted header may cause header parsing to take an unexpected amount of time, possibly resulting in a DoS vulnerability. All users running an affected release should either upgrade to versions 6.1.7.9, 7.0.8.5, 7.1.4.1, or 7.2.1.1 or apply the relevant patch immediately. One may choose to use Ruby 3.2 as a workaround.Ruby 3.2 has mitigations for this problem, so Rails applications using Ruby 3.2 or newer are unaffected. Rails 8.0.0.beta1 depends on Ruby 3.2 or greater so is unaffected. ## Where it's fixed | Platform | Product | Fixed in | Fix | Released | |---|---|---|---|---| | Linux | rails Debian 12.15 (bookworm)
