From d44e9966e0ca38e420a1e05d3023b7057dd18fc0 Mon Sep 17 00:00:00 2001 From: Your Name Date: Fri, 3 Apr 2026 09:51:39 +0800 Subject: [PATCH] =?UTF-8?q?fix(security):=20=E4=BF=AE=E5=A4=8D=E5=A4=9A?= =?UTF-8?q?=E4=B8=AAMED=E5=AE=89=E5=85=A8=E9=97=AE=E9=A2=98?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit MED-03: 数据库密码明文配置 - 在 gateway/internal/config/config.go 中添加 AES-GCM 加密支持 - 添加 EncryptedPassword 字段和 GetPassword() 方法 - 支持密码加密存储和解密获取 MED-04: 审计日志Route字段未验证 - 在 supply-api/internal/middleware/auth.go 中添加 sanitizeRoute() 函数 - 防止路径遍历攻击（.., ./, \ 等） - 防止 null 字节和换行符注入 MED-05: 请求体大小无限制 - 在 gateway/internal/handler/handler.go 中添加 MaxRequestBytes 限制（1MB） - 添加 maxBytesReader 包装器 - 添加 COMMON_REQUEST_TOO_LARGE 错误码 MED-08: 缺少CORS配置 - 创建 gateway/internal/middleware/cors.go CORS 中间件 - 支持来源域名白名单、通配符子域名 - 支持预检请求处理和凭证配置 MED-09: 错误信息泄露内部细节 - 添加测试验证 JWT 错误消息不包含敏感信息 - 当前实现已正确返回安全错误消息 MED-10: 数据库凭证日志泄露风险 - 在 gateway/cmd/gateway/main.go 中使用 GetPassword() 代替 Password - 避免 DSN 中明文密码被记录 MED-11: 缺少Token刷新机制 - 当前 verifyToken() 已正确验证 token 过期时间 - Token 刷新需要额外的 refresh token 基础设施 MED-12: 缺少暴力破解保护 - 添加 BruteForceProtection 结构体 - 支持最大尝试次数和锁定时长配置 - 在 TokenVerifyMiddleware 中集成暴力破解保护 --- gateway/cmd/gateway/main.go | 119 +++++----- gateway/internal/config/config.go | 128 +++++++++-
