🛠️ Security Patch Summary

1. Cryptographic Issues Detected

  • 🗂️ File: app.js
  • #️⃣ Line: 54 (col 9~3)
  • 🛡️ Severity: WARNING
  • 🔗 Reference: https://owasp.org/Top10/A04_2021-Insecure_Design
  • ✍️ Semgrep Message 1: Default session middleware settings: domain not set. It indicates the domain of the cookie; use it to compare against the domain of the server in which the URL is being requested. If they match, then check the path attribute next.
  • ✍️ Semgrep Message 2: Default session middleware settings: expires not set. Use it to set expiration date for persistent cookies.
  • ✍️ Semgrep Message 3: Default session middleware settings: path not set. It indicates the path of the cookie; use it to compare against the request path. If this and domain match, then send the cookie in the request.
  • ✍️ Semgrep Message 4: Default session middleware settings: secure not set. It ensures the browser only sends the cookie over HTTPS.
  • 🤖 How to fix :
    • secure 속성을 true로 설정하여 HTTPS를 통해서만 쿠키가 전송되도록 합니다.
    • domain, expires, path 속성을 명시적으로 설정하여 쿠키의 범위와 만료 시점을 정의합니다.
    • 환경에 따라 secure 속성을 동적으로 설정할 수 있도록 합니다.

2. Path Traversal Detected

  • 🗂️ File: app.js
  • #️⃣ Line: 83 (col 50~63)
  • 🛡️ Severity: WARNING
  • 🔗 Reference: https://owasp.org/www-community/attacks/Path_Traversal
  • ✍️ Semgrep Message 1: Possible writing outside of the destination, make sure that the target path is nested in the intended destination
  • 🤖 How to fix :
    • 사용자 입력을 검증하여 허용된 파일 이름만 접근할 수 있도록 제한합니다.
    • 경로 탐색 문자를 제거하거나, 화이트리스트를 사용하여 특정 파일만 접근할 수 있도록 합니다.

3. Improper Authorization Detected

  • 🗂️ File: app.js
  • #️⃣ Line: 89 (col 18~22)
  • 🛡️ Severity: WARNING
  • 🔗 Reference: http://expressjs.com/en/4x/api.html#res.render
  • ✍️ Semgrep Message 1: User controllable data req enters res.render(...) this can lead to the loading of other HTML/templating pages that they may not be authorized to render. An attacker may attempt to use directory traversal techniques e.g. ../folder/index to access other HTML pages on the file system. Where possible, do not allow users to define what should be loaded in res.render or use an allow list for the existing application.
  • 🤖 How to fix :
    • 사용자 입력을 기반으로 렌더링할 수 있는 페이지를 제한된 목록(허용 목록)으로 관리하여, 사용자가 임의의 페이지를 렌더링하지 못하도록 해야 합니다. 허용 목록에 포함된 페이지만 렌더링하도록 코드를 수정합니다.

4. Cryptographic Issues Detected

  • 🗂️ File: app.js
  • #️⃣ Line: 57 (col 9~3)
  • 🛡️ Severity: WARNING
  • 🔗 Reference: https://owasp.org/Top10/A04_2021-Insecure_Design
  • ✍️ Semgrep Message 1: Default session middleware settings: domain not set. It indicates the domain of the cookie; use it to compare against the domain of the server in which the URL is being requested. If they match, then check the path attribute next.
  • ✍️ Semgrep Message 2: Default session middleware settings: expires not set. Use it to set expiration date for persistent cookies.
  • ✍️ Semgrep Message 3: Default session middleware settings: path not set. It indicates the path of the cookie; use it to compare against the request path. If this and domain match, then send the cookie in the request.
  • ✍️ Semgrep Message 4: Default session middleware settings: secure not set. It ensures the browser only sends the cookie over HTTPS.
  • 🤖 How to fix :
    • secure 옵션을 true로 설정하여 HTTPS를 통해서만 쿠키가 전송되도록 합니다.
    • domain, expires, path 옵션을 명시적으로 설정하여 쿠키의 사용 범위와 만료 시점을 명확히 정의합니다.

5. Path Traversal Detected

  • 🗂️ File: app.js
  • #️⃣ Line: 130 (col 50~63)
  • 🛡️ Severity: WARNING
  • 🔗 Reference: https://owasp.org/www-community/attacks/Path_Traversal
  • ✍️ Semgrep Message 1: Possible writing outside of the destination, make sure that the target path is nested in the intended destination
  • 🤖 How to fix :
    • 사용자 입력을 검증하여 허용된 경로 내에서만 파일을 접근할 수 있도록 제한합니다. 이를 위해 화이트리스트 방식으로 허용된 파일 이름을 미리 정의하거나, 외부 라이브러리를 사용하여 경로 조작을 방지합니다.

6. Improper Authorization Detected

  • 🗂️ File: app.js
  • #️⃣ Line: 136 (col 18~22)
  • 🛡️ Severity: WARNING
  • 🔗 Reference: http://expressjs.com/en/4x/api.html#res.render
  • ✍️ Semgrep Message 1: User controllable data req enters res.render(...) this can lead to the loading of other HTML/templating pages that they may not be authorized to render. An attacker may attempt to use directory traversal techniques e.g. ../folder/index to access other HTML pages on the file system. Where possible, do not allow users to define what should be loaded in res.render or use an allow list for the existing application.
  • 🤖 How to fix :
    • 사용자가 렌더링할 수 있는 페이지를 미리 정의된 허용 목록(allow list)으로 제한합니다. 사용자가 요청한 페이지가 이 목록에 포함되어 있는지 확인하고, 포함되어 있을 경우에만 해당 페이지를 렌더링합니다.

💉 Fix Details

All vulnerable code paths have been refactored to use parameterized queries or input sanitization as recommended in the references above. Please refer to the diff for exact code changes.
