Negative directive in the template matcher seems to not work with the case-insensitive directive

[x676f64]

Nuclei version: v3.2.4

Current Behavior:

Nuclei fails to match on a finding when the case-insensitive directive and the negative directive are used together.
For example, the cookies-without-httponly-secure matcher should only identify endpoints that lack both httponly and secure but the strings they match on have different cases depending on the web server. I observed this issue in the wild so attempted to modify the template to use case-insensitivity with negative but it does not appear to work.

Expected Behavior:

The expected behavior is that this template will only return a positive finding if both httponly and secure exist in the set-cookie directive but do to case variations of web servers, this is not always a match. Attempting to add the case-insensitive directive did not work.

I have to build a template like this to properly handle the potentials and this still doesn't cover some crazy edge case.

  author: princechaddha,Mr.Bobo HP
  severity: info
  description: |
    Checks whether cookies in the HTTP response contain the HttpOnly attribute. If the HttpOnly flag is set, it means that the cookie is HTTP-only
  impact: |
    Lack of HttpOnly flag on cookies increases the risk of client-side attacks, compromising user session security and data privacy.
  remediation: |
    Ensure that all cookies are set with the HttpOnly attribute to prevent client-side access.
