gem.coop: rack

Rack provides a minimal, modular and adaptable interface for developing web applications in Ruby. By wrapping HTTP requests and responses in the simplest way possible, it unifies and distills the API for web servers, web frameworks, and software in between (the so-called middleware) into a single method call.

  • Rack::Sendfile header-based X-Accel-Mapping regex injection enables unauthorized X-Accel-Redirect
  • Rack's multipart parsing without Content-Length header allows unbounded chunked file uploads
  • Rack has a root directory disclosure via unescaped regex interpolation in Rack::Directory
  • Rack has quadratic complexity in Rack::Utils.select_best_encoding via wildcard Accept-Encoding header
  • Rack: Forwarded Header semicolon injection enables Host and Scheme spoofing
  • Rack's improper unfolding of folded multipart headers preserves CRLF in parsed parameter values
  • Rack's greedy multipart boundary parsing can cause parser differentials and WAF bypass.
  • Rack's multipart header parsing allows Denial of Service via escape-heavy quoted parameters
  • Rack's multipart byte range processing allows denial of service via excessive overlapping ranges
  • Rack:: Static header_rules bypass via URL-encoded paths
  • Rack::Static prefix matching can expose unintended files under the static root

  • Rack has a Directory Traversal via Rack:Directory
  • Rack is vulnerable to a memory-exhaustion DoS through unbounded URL-encoded body parsing
  • Rack has a Possible Information Disclosure Vulnerability

  • Rack has an unsafe default in Rack::QueryParser allows params_limit bypass via semicolon-separated parameters
  • ReDoS Vulnerability in Rack::Multipart handle_mime_head
