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.
