Title
Plack::Middleware::Security::Common versions before 0.13.1 for Perl did not block header injections in request paths
Summary
Plack::Middleware::Security::Common versions before 0.13.1 for Perl did not block header injections in request paths.
The header injection rule was ineffective at blocking header injections in the request paths unless they were double-encoded, for example,
GET /path\r\nHTTP/1.1\r\nHost: secret.example.com
Note that it is unclear whether request paths with CRLF followed by additional headers would be blocked by reverse proxies, or how they would be processed by Plack-based servers.
