CWE-284 (访问控制不恰当) — Vulnerability Class 2612

2612 vulnerabilities classified as CWE-284 (访问控制不恰当). AI Chinese analysis included.

CWE-284 represents a critical security weakness where software fails to properly restrict access to sensitive resources, allowing unauthorized actors to interact with data or functions they should not reach. This flaw typically arises when developers neglect to implement robust authentication or authorization checks, enabling attackers to bypass security controls through direct URL manipulation, token forgery, or privilege escalation techniques. Exploitation often leads to severe consequences, including data breaches, unauthorized system modifications, or complete service disruption. To mitigate this risk, developers must enforce strict access control policies at every layer of the application architecture. This involves implementing comprehensive identity verification, applying the principle of least privilege, and rigorously validating user permissions before granting access to any protected resource, ensuring that only authenticated and authorized users can perform specific actions.

MITRE CWE Description
The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. Access control involves the use of several protection mechanisms such as: Authentication (proving the identity of an actor) Authorization (ensuring that a given actor can access a resource), and Accountability (tracking of activities that were performed) When any mechanism is not applied or otherwise fails, attackers can compromise the security of the product by gaining privileges, reading sensitive information, executing commands, evading detection, etc. There are two distinct behaviors that can introduce access control weaknesses: Specification: incorrect privileges, permissions, ownership, etc. are explicitly specified for either the user or the resource (for example, setting a password file to be world-writable, or giving administrator capabilities to a guest user). This action could be performed by the program or the administrator. Enforcement: the mechanism contains errors that prevent it from properly enforcing the specified access control requirements (e.g., allowing the user to specify their own privileges, or allowing a syntactically-incorrect ACL to produce insecure settings). This problem occurs within the program itself, in that it does not actually enforce the intended security policy that the administrator specifies.
Common Consequences (1)
Other Varies by Context
Mitigations (2)
Architecture and Design, Operation Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
Architecture and Design Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separatio…
Examples (2)
This code temporarily raises the program's privileges to allow creation of a new user folder.
def makeNewUserDir(username): if invalidUsername(username): #avoid CWE-22 and CWE-78 print('Usernames cannot contain invalid characters') return False try: raisePrivileges() os.mkdir('/home/' + username) lowerPrivileges() except OSError: print('Unable to create new user directory for user:' + username) return False return True
