Security Advisories 🚨

🚨 Puma's header normalization allows for client to clobber proxy set headers

Impact

Clients could clobber values set by intermediate proxies (such as X-Forwarded-For) by providing a underscore version of the same header (X-Forwarded_For). Any users trusting headers set by their proxy may be affected. Attackers may be able to downgrade connections to HTTP (non-SSL) or redirect responses, which could cause confidentiality leaks if combined with a separate MITM attack.

Patches

v6.4.3/v5.6.9 now discards any headers using underscores if the non-underscore version also exists. Effectively, allowing the proxy defined headers to always win.

Workarounds

Nginx has a underscores_in_headers configuration variable to discard these headers at the proxy level.

Any users that are implicitly trusting the proxy defined headers for security or availability should immediately cease doing so until upgraded to the fixed versions.

🚨 Puma HTTP Request/Response Smuggling vulnerability

Impact

Prior to versions 6.4.2 and 5.6.8, puma exhibited dangerous behavior when parsing chunked transfer encoding bodies.

Fixed versions limit the size of chunk extensions. Without this limit, an attacker could cause unbounded resource (CPU, network bandwidth) consumption.

Patches

The vulnerability has been fixed in 6.4.2 and 5.6.8.

Workarounds

No known workarounds.

🚨 Puma HTTP Request/Response Smuggling vulnerability

Impact

Prior to version 6.3.1, puma exhibited incorrect behavior when parsing chunked transfer encoding bodies and zero-length Content-Length headers in a way that allowed HTTP request smuggling.

The following vulnerabilities are addressed by this advisory:

  • Incorrect parsing of trailing fields in chunked transfer encoding bodies
  • Parsing of blank/zero-length Content-Length headers

Patches

The vulnerability has been fixed in 6.3.1 and 5.6.7.

Workarounds

No known workarounds.
