Description

llhttp allows HTTP Request Smuggling via Improper Delimiting of Header Fields

The llhttp parser in the http module in Node.js does not strictly use the CRLF sequence to delimit HTTP requests. The LF character (without CR) is sufficient to delimit HTTP header fields in the lihttp parser. According to RFC7230 section 3, only the CRLF sequence should delimit each header-field. This can lead to HTTP Request Smuggling (HRS).

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs no privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality low, integrity low, availability none.

CVSS metrics in full

The score comes from this vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N

  • Attack vector: Network — reachable from anywhere that can route to the service.
  • Attack complexity: Low — the attack works reliably, with no preparation.
  • Privileges required: None — an unauthenticated stranger can try it.
  • User interaction: None — nobody has to be tricked into anything.
  • Scope: Unchanged — the damage stays inside the vulnerable component.
  • Confidentiality impact: Low — limited, and the attacker does not choose what is affected.
  • Integrity impact: Low — limited, and the attacker does not choose what is affected.
  • Availability impact: None.
