Astra Linux – Vulnerability in Ruby-Rack

Rack is a modular Ruby web server interface. Prior to versions 2.2.23, 3.1.21, and 3.2.6, Rack::Static used a simple string prefix check to determine whether a request should be served as a static file. When configured with URL prefixes like "/css", it matched any request path that began with tha...

Astra Linux – Vulnerability in Ruby-Rack

Rack provides an interface for developing web applications in Ruby. Before versions 2.2.13, 3.0.14, and 3.1.12, Rack::Static could serve files under the specified root: even if urls: was provided. This might lead to unexpected access to other files under the same root: directory. The vulnerabilit...

GHSA-Q4QF-9J86-F5MH Rack:: Static header_rules bypass via URL-encoded paths

Summary Rack::Staticapplicablerules evaluates several headerrules types against the raw URL-encoded PATHINFO, while the underlying file-serving path is decoded before the file is served. As a result, a request for a URL-encoded variant of a static path can serve the same file without the headers...

Rack::Static prefix matching can expose unintended files under the static root

Summary Rack::Static determines whether a request should be served as a static file using a simple string prefix check. When configured with URL prefixes such as "/css", it matches any request path that begins with that string, including unrelated paths such as "/css-config.env" or...

Incorrect Behavior Order: Validate Before Canonicalize

Overview rack is 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 singl...
