| VCID-7zgg-tvu3-r7gt | Rack vulnerable to ReDoS in content type parsing (2nd degree polynomial) ### Summary ```ruby module Rack class MediaType SPLIT_PATTERN = %r{\s*[;,]\s*} ``` The above regexp is subject to ReDos. 50K blank characters as a prefix to the header will take over 10s to split. ### PoC A simple HTTP request with lots of blank characters in the content-type header: ```ruby request["Content-Type"] = (" " * 50_000) + "a," ``` ### Impact It's a very easy to craft ReDoS. Like all ReDoS the impact is debatable. |
