CVSS: 9.8EPSS: 0%CPEs: 3EXPL: 0CVE-2025-25184 – Possible Log Injection in Rack::CommonLogger
https://notcve.org/view.php?id=CVE-2025-25184
12 Feb 2025 — Rack provides an interface for developing web applications in Ruby. Prior to versions 2.2.11, 3.0.12, and 3.1.11, Rack::CommonLogger can be exploited by crafting input that includes newline characters to manipulate log entries. The supplied proof-of-concept demonstrates injecting malicious content into logs. When a user provides the authorization credentials via Rack::Auth::Basic, if success, the username will be put in env['REMOTE_USER'] and later be used by Rack::CommonLogger for logging purposes. The iss... • https://github.com/rack/rack/commit/074ae244430cda05c27ca91cda699709cfb3ad8e • CWE-93: Improper Neutralization of CRLF Sequences ('CRLF Injection') CWE-117: Improper Output Neutralization for Logs •

https://notcve.org/view.php?id=CVE-2024-26141
28 Feb 2024 — Rack is a modular Ruby web server interface. Carefully crafted Range headers can cause a server to respond with an unexpectedly large response. Responding with such large responses could lead to a denial of service issue. Vulnerable applications will use the `Rack::File` middleware or the `Rack::Utils.byte_ranges` methods (this includes Rails applications). The vulnerability is fixed in 3.0.9.1 and 2.2.8.1. • https://discuss.rubyonrails.org/t/possible-dos-vulnerability-with-range-header-in-rack/84944 • CWE-400: Uncontrolled Resource Consumption CWE-1333: Inefficient Regular Expression Complexity •
