CWE-306 关键功能的认证机制缺失 类漏洞列表 1656

CWE-306 关键功能的认证机制缺失 类弱点 1656 条 CVE 漏洞汇总，含 AI 中文分析。

CWE-306指关键功能缺乏身份验证，属于访问控制缺陷。攻击者可直接调用需高权限或消耗大量资源的功能，无需提供凭证，从而实施未授权操作或资源耗尽攻击。开发者应确保所有敏感操作强制实施身份验证机制，严格校验用户身份，防止未认证请求访问关键业务逻辑，保障系统安全。

MITRE CWE 官方描述
CWE：CWE-306 关键功能缺少身份验证 (Missing Authentication for Critical Function) 英文：该产品对于需要可证明的用户身份或消耗大量资源的功能，未执行任何身份验证 (authentication)。
常见影响 (1)
Access Control, Other Gain Privileges or Assume Identity, Varies by Context
Exposing critical functionality essentially provides an attacker with the privilege level of that functionality. The consequences will depend on the associated functionality, but they can range from reading or modifying sensitive data, accessing administrative or other privileged functionality, or p…
缓解措施 (5)
Architecture and Design Divide the software into anonymous, normal, privileged, and administrative areas. Identify which of these areas require a proven user identity, and use a centralized authentication capability. Identify all potential communication channels, or other means of interaction with the software, to ensure that all channels are appropriately protected, including those channels that are assumed to be access…
Architecture and Design For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
Architecture and Design Where possible, avoid implementing custom, "grow-your-own" authentication routines and consider using authentication capabilities as provided by the surrounding framework, operating system, or environment. These capabilities may avoid common weaknesses that are unique to authentication; support automatic auditing and tracking; and make it easier to provide a clear separation between authentication…
Architecture and Design Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. For example, consider using libraries with authentication capabilities such as OpenSSL or the ESAPI Authenticator [REF-45].
Implementation, System Configuration, Operation When storing data in the cloud (e.g., S3 buckets, Azure blobs, Google Cloud Storage, etc.), use the provider's controls to require strong authentication for users who should be allowed to access the data [REF-1297] [REF-1298] [REF-1302].
代码示例 (2)
In the following Java example the method createBankAccount is used to create a BankAccount object for a bank management application.
public BankAccount createBankAccount(String accountNumber, String accountType, String accountName, String accountSSN, double balance) { BankAccount account = new BankAccount(); account.setAccountNumber(accountNumber); account.setAccountType(accountType); account.setAccountOwnerName(accountName); account.setAccountOwnerSSN(accountSSN); account.setBalance(balance); return account; }
Bad · Java
private boolean isUserAuthentic = false; // authenticate user, // if user is authenticated then set variable to true // otherwise set variable to false public boolean authenticateUser(String username, String password) { ... } public BankAccount createNewBankAccount(String accountNumber, String accountType, String accountName, String accountSSN, double balance) { BankAccount account = null; if (isUserAuthentic) { account = new BankAccount(); account.setAccountNumber(accountNumber); account.setAccountType(accountType); account.setAccountOwnerName(accountName); account.setAccountOwnerSSN(accountS

In 2022, the OT:ICEFALL study examined products by 10 different Operational Technology (OT) vendors. The researchers reported 56 vulnerabilities and said that the products were "insecure by design" [REF-1283]. If exploited, these vulnerabilities often allowed adversaries to change how the products operated, ranging from denial of service to changing the code that the products executed. Since these…
