Workflow

工作流程

Execute these steps in order:

按以下顺序执行步骤：

Step 1: Detect Project Context

步骤1：检测项目上下文

Identify the technology stack to apply appropriate review patterns.

1. Check for package managers and frameworks:

bash

undefined

识别技术栈，以应用对应的审查模式。

1. 检查包管理器与框架：

bash

undefined

Node.js

ls package.json 2>/dev/null && cat package.json | head -50

Python

ls requirements.txt setup.py pyproject.toml 2>/dev/null

.NET

ls *.csproj *.sln 2>/dev/null

Java

ls pom.xml build.gradle 2>/dev/null

Go

ls go.mod 2>/dev/null


**2. Identify authentication libraries in use:**

| Stack | Common Auth Libraries |
|-------|----------------------|
| Node.js | passport, express-session, next-auth, @auth/core, msal-node |
| Python | flask-login, django-allauth, authlib, msal |
| .NET | Microsoft.Identity.Web, IdentityServer |
| Java | spring-security-oauth2, keycloak |
| Go | coreos/go-oidc, golang.org/x/oauth2 |

**3. Record findings:**
- Framework detected: [name]
- Auth library: [name] or "custom/none detected"
- Package manager: [name]

Proceed to Step 2.

ls go.mod 2>/dev/null


**2. 识别正在使用的认证库：**

| 技术栈 | 常用认证库 |
|-------|----------------------|
| Node.js | passport, express-session, next-auth, @auth/core, msal-node |
| Python | flask-login, django-allauth, authlib, msal |
| .NET | Microsoft.Identity.Web, IdentityServer |
| Java | spring-security-oauth2, keycloak |
| Go | coreos/go-oidc, golang.org/x/oauth2 |

**3. 记录检测结果：**
- 检测到的框架：[名称]
- 认证库：[名称] 或 "未检测到自定义/任何库"
- 包管理器：[名称]

进入步骤2。

Step 2: Identify Authentication-Related Files

步骤2：识别认证相关文件

Build a list of files to review using glob and grep patterns.

1. Search by file path patterns:

bash

undefined

使用通配符和grep模式构建待审查文件列表。

1. 按文件路径模式搜索：

bash

undefined

Find auth-related directories and files

查找认证相关目录与文件

find . -type f (
-path "/auth/" -o
-path "/authentication/" -o
-path "/identity/" -o
-path "/login/" -o
-path "/session/" -o
-path "/middleware/" -o
-name "auth" -o
-name "identity" -o
-name "oidc" -o
-name "oauth" -o
-name "session" -o
-name "login"
) -not -path "/node_modules/" -not -path "/.git/" -not -path "/vendor/" 2>/dev/null


**2. Search by content patterns:**

```bash


**2. 按内容模式搜索：**

```bash

Find files containing auth-related code

查找包含认证相关代码的文件


**3. Also check configuration files:**

```bash


**3. 同时检查配置文件：**

```bash

Config files that may contain auth settings

可能包含认证设置的配置文件

find . -type f (
-name ".env" -o
-name "appsettings*.json" -o
-name "config*.json" -o
-name "config*.yaml" -o
-name "config*.yml"
) -not -path "/node_modules/" 2>/dev/null


**4. Build review list:**
- Combine results, remove duplicates
- Prioritize: config files first, then middleware, then auth modules
- If no files found, inform user: "No authentication-related files detected. Ensure the codebase contains auth implementation."

Read each identified file before proceeding to Step 3.

find . -type f (
-name ".env" -o
-name "appsettings*.json" -o
-name "config*.json" -o
-name "config*.yaml" -o
-name "config*.yml"
) -not -path "/node_modules/" 2>/dev/null


**4. 构建审查列表：**
- 合并结果，去重
- 优先级：配置文件优先，其次是中间件，最后是认证模块
- 若未找到文件，告知用户："未检测到认证相关文件，请确保代码库包含认证实现。"

在进入步骤3前，阅读所有识别出的文件。

Requirement: Session cookies must have HttpOnly, Secure, and SameSite flags.

Stack-specific patterns:

Node.js/Express:

javascript

// Check express-session or cookie config
cookie: {
  httpOnly: true,   // MUST be true
  secure: true,     // MUST be true in production
  sameSite: 'strict' // MUST be 'strict' or 'lax'
}

Python/Flask:

python

SESSION_COOKIE_HTTPONLY = True   # MUST be True
SESSION_COOKIE_SECURE = True     # MUST be True
SESSION_COOKIE_SAMESITE = 'Strict'  # MUST be 'Strict' or 'Lax'

Python/Django:

```
- Enables refresh tokens, needs data retention justification
Custom scopes - Verify business necessity

Excessive scopes (Fail):

```
User.ReadWrite.All
```
or similar admin scopes without authorization
Multiple resource scopes when fewer would suffice
```
Directory.Read.All
```
for apps not needing directory access

Finding format:

| ⚠️ **Warning** | {file}:{line} | Requesting '{scope}' scope but usage not detected | Reduce scopes to minimum required (Privacy Act compliance) |

要求： 仅请求必要的最小范围（隐私法案、最小权限原则）。

搜索模式：

regex

scope[s]?\s*[:=]\s*["'][^"']*["']

可接受的最小范围：

```
openid
```
- OIDC必需
```
profile
```
- 若需要用户显示名称
```
email
```
- 若需要用户邮箱地址

需合理依据的范围（警告）：

```
offline_access
```
- 启用刷新令牌，需数据保留的合理依据
自定义范围 - 验证业务必要性

过度范围（失败）：

```

8.4 Detailed Findings (for each Fail/Warning)

8.4 详细结果说明（针对每个失败/警告）

For critical failures, provide detailed remediation:

--------------------------------------------------------------------------------
[Auth Error] Hardcoded Client Secret
--------------------------------------------------------------------------------
File: src/auth/config.ts:15
Category: A. OIDC Implementation Standards
Severity: FAIL
Reference: ITSG-33 IA-5 (Authenticator Management)

Code Found:
┌─────────────────────────────────────────────────────────────
│ const config = {
│   clientId: 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx',
│   clientSecret: 'abc123secret456xyz'  // <-- VIOLATION
│ };
└─────────────────────────────────────────────────────────────

Issue:
Client secrets must never be stored in source code. This violates
ITSG-33 IA-5 (Authenticator Management) and TBS Standard on Security
Tabs. Exposed secrets can lead to unauthorized access to the identity
provider and impersonation attacks.

Recommended Action:
1. Remove the secret from source code immediately
2. Store in environment variable:
   - process.env.AZURE_CLIENT_SECRET (Node.js)
   - os.environ['AZURE_CLIENT_SECRET'] (Python)
3. For production: Use Azure Key Vault or equivalent secrets manager
4. CRITICAL: Rotate the exposed secret in Entra ID immediately

Remediation Example:
┌─────────────────────────────────────────────────────────────
│ const config = {
│   clientId: process.env.AZURE_CLIENT_ID,
│   clientSecret: process.env.AZURE_CLIENT_SECRET
│ };
└─────────────────────────────────────────────────────────────

--------------------------------------------------------------------------------

针对严重失败，提供详细修复指导：

--------------------------------------------------------------------------------
[认证错误] 硬编码客户端密钥
--------------------------------------------------------------------------------
文件: src/auth/config.ts:15
类别: A. OIDC实现标准
严重程度: 失败
参考标准: ITSG-33 IA-5（认证器管理）

发现的代码:
┌─────────────────────────────────────────────────────────────
│ const config = {
│   clientId: 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx',
│   clientSecret: 'abc123secret456xyz'  // <-- 违规
│ };
└─────────────────────────────────────────────────────────────

问题说明:
客户端密钥绝不可存储在源代码中。此行为违反了ITSG-33 IA-5（认证器管理）和TBS安全标签标准。暴露的密钥可能导致对身份提供商的未授权访问与冒充攻击。

建议操作:
1. 立即从源代码中移除密钥
2. 存储在环境变量中:
   - process.env.AZURE_CLIENT_SECRET（Node.js）
   - os.environ['AZURE_CLIENT_SECRET']（Python）
3. 生产环境：使用Azure Key Vault或等效的密钥管理服务
4. 紧急：立即在Entra ID中轮换暴露的密钥

修复示例:
┌─────────────────────────────────────────────────────────────
│ const config = {
│   clientId: process.env.AZURE_CLIENT_ID,
│   clientSecret: process.env.AZURE_CLIENT_SECRET
│ };
└─────────────────────────────────────────────────────────────
