Security Advisories 🚨

🚨 Local File Inclusion in Rack::Static

Summary

Rack::Static can serve files under the specified root: even if urls: are provided, which may expose other files under the specified root: unexpectedly.

Details

The vulnerability occurs because Rack::Static does not properly sanitize user-supplied paths before serving files. Specifically, encoded path traversal sequences are not correctly validated, allowing attackers to access files outside the designated static file directory.

Impact

By exploiting this vulnerability, an attacker can gain access to all files under the specified root: directory, provided they are able to determine then path of the file.

Mitigation

• Update to the latest version of Rack, or
• Remove usage of Rack::Static, or
• Ensure that root: points at a directory path which only contains files which should be accessed publicly.

It is likely that a CDN or similar static file server would also mitigate the issue.

🚨 Escape Sequence Injection vulnerability in Rack lead to Possible Log Injection

Summary

Rack::Sendfile can be exploited by crafting input that includes newline characters to manipulate log entries.

Details

The Rack::Sendfile middleware logs unsanitized header values from the X-Sendfile-Type header. An attacker can exploit this by injecting escape sequences (such as newline characters) into the header, resulting in log injection.

Impact

This vulnerability can distort log files, obscure attack traces, and complicate security auditing.

Mitigation

• Update to the latest version of Rack, or
• Remove usage of Rack::Sendfile.

🚨 Possible Log Injection in Rack::CommonLogger

Summary

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.

Details

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 issue occurs when a server intentionally or unintentionally allows a user creation with the username contain CRLF and white space characters, or the server just want to log every login attempts. If an attacker enters a username with CRLF character, the logger will log the malicious username with CRLF characters into the logfile.

Impact

Attackers can break log formats or insert fraudulent entries, potentially obscuring real activity or injecting malicious data into log files.

Mitigation

• Update to the latest version of Rack.

🚨 Rack ReDoS Vulnerability in HTTP Accept Headers Parsing

Summary

A Regular Expression Denial of Service (ReDoS) vulnerability exists in the Rack::Request::Helpers module when parsing HTTP Accept headers. This vulnerability can be exploited by an attacker sending specially crafted Accept-Encoding or Accept-Language headers, causing the server to spend excessive time processing the request and leading to a Denial of Service (DoS).

Details

The fix for GHSA-54rr-7fvw-6x8f was not applied to the main branch and thus while the issue was fixed for the Rack v3.0 release series, it was not fixed in the v3.1 release series until v3.1.5.

Security Advisories 🚨

🚨 REXML ReDoS vulnerability

Impact

The REXML gem before 3.3.9 has a ReDoS vulnerability when it parses an XML that has many digits between &# and x...; in a hex numeric character reference (&#x...;).

This does not happen with Ruby 3.2 or later. Ruby 3.1 is the only affected maintained Ruby. Note that Ruby 3.1 will reach EOL on 2025-03.

Patches

The REXML gem 3.3.9 or later include the patch to fix the vulnerability.

Workarounds

Use Ruby 3.2 or later instead of Ruby 3.1.

🚨 REXML denial of service vulnerability

Impact

The REXML gem before 3.3.6 has a DoS vulnerability when it parses an XML that has many deep elements that have same local name attributes.

If you need to parse untrusted XMLs with tree parser API like REXML::Document.new, you may be impacted to this vulnerability. If you use other parser APIs such as stream parser API and SAX2 parser API, this vulnerability is not affected.

Patches

The REXML gem 3.3.6 or later include the patch to fix the vulnerability.

Workarounds

Don't parse untrusted XMLs with tree parser API.

🚨 REXML DoS vulnerability

Impact

The REXML gem before 3.3.2 has a DoS vulnerability when it parses an XML that has many entity expansions with SAX2 or pull parser API.

If you need to parse untrusted XMLs with SAX2 or pull parser API, you may be impacted to this vulnerability.

Patches

The REXML gem 3.3.3 or later include the patch to fix the vulnerability.

Workarounds

Don't parse untrusted XMLs with SAX2 or pull parser API.

🚨 REXML DoS vulnerability

Impact

The REXML gem before 3.3.2 has some DoS vulnerabilities when it parses an XML that has many specific characters such as whitespace character, >] and ]>.

If you need to parse untrusted XMLs, you may be impacted to these vulnerabilities.

Patches

The REXML gem 3.3.3 or later include the patches to fix these vulnerabilities.

Workarounds

Don't parse untrusted XMLs.

🚨 REXML denial of service vulnerability

Impact

The REXML gem before 3.3.1 has some DoS vulnerabilities when it parses an XML that has many specific characters such as <, 0 and %>.

If you need to parse untrusted XMLs, you may be impacted to these vulnerabilities.

Patches

The REXML gem 3.3.2 or later include the patches to fix these vulnerabilities.
