[BUG] DSL Responses Do Not Work Properly with Code Protocol

[hipotermia]

Is there an existing issue for this?

• I have searched the existing issues.

Current Behavior

When using the code protocol, DSL responses are not functioning as expected.

• status_code_1 == 200 evaluates to true.
• status_code_2 == 200 evaluates to true.

However, when comparing the two status codes:

• status_code_1 == status_code_2 does not match.

And by removing the code protocol, works.

Expected Behavior

status_code_1 == status_code_2 should match if are equal, regardless if code is being used.

Steps To Reproduce

The following template should hit, but it doesn't.

id: test

info:
  name: test
  author: hipotermia
  severity: high

code:
  - engine:
      - py
      - python3
    source: |
      print('/')

http:
  - raw:
      - |+
        GET / HTTP/1.1
        Host: {{Hostname}}

      - |+
        GET / HTTP/1.1
        Host: {{Hostname}}

    matchers:
      - type: dsl
        dsl:
          - "status_code_1 == status_code_2"

Relevant log output

No response

Environment

• OS: Lunux
• Nuclei: 3.3.5

Anything else?

I'm going to be off for a few days, so I’m dropping this here as a note (for myself as well). I suspect that the underlying issue might be found here:

nuclei/pkg/tmplexec/multiproto/multi.go

Lines 119 to 120 in ff23949

	values := m.options.GetTemplateCtx(inputItem.MetaInput).GetAll()
	err := req.ExecuteWithResults(inputItem, output.InternalEvent(values), nil, multiProtoCallback)

This was introduced in #5426.
