Summary
The food-waste-management-system may allow remote requests to the Admin Signup functionality without properly enforcing authentication when the sign argument is manipulated. An attacker who can reach the affected endpoint could potentially access administrative functionality or perform actions intended for authenticated users.
Affected context
The weakness occurs in the Admin Signup component implemented by admin/signup.php. It may affect deployments where the endpoint is remotely reachable and authentication decisions rely on the sign argument or related request-controlled values without consistently verifying the caller's identity. The available report does not identify fixed or affected release versions.
Exploit preconditions
- Attack surface: Remotely reachable Admin Signup HTTP endpoint
- Required access: Network access to the affected application; authenticated access may not be required
- Trigger point: Processing of requests to
admin/signup.phpinvolving thesignargument - Why exploitation is possible: The application may omit or incorrectly apply authentication checks before allowing access to protected administrative functionality
Why this happens
The underlying bug is an authentication enforcement failure. A security-sensitive operation appears to trust a request parameter or control-flow condition without requiring a reliable, server-side proof of the caller's identity. This maps primarily to CWE-306: Missing Authentication for Critical Function, with CWE-287: Improper Authentication also relevant when authentication logic exists but does not correctly validate access.
Potential impact
- An unauthenticated attacker may access administrative functionality
- Attackers could create, modify, or manage administrative accounts
- Unauthorized changes could affect application data or configuration
- The application may experience loss of confidentiality, integrity, or availability
General mitigation guidance
Mitigation generally focuses on making authentication mandatory for every sensitive administrative operation rather than relying on request parameters to indicate trust.
Common defensive patterns include:
- Enforcing centralized, server-side authentication and authorization checks before processing the operation
- Treating
signand all other client-controlled values as untrusted input - Applying deny-by-default access controls to administrative routes
- Separating account creation and administrative workflows from publicly reachable endpoints
- Using least-privilege roles and limiting administrative capabilities
- Adding regression tests that verify unauthenticated and improperly authorized requests are rejected
How teams detect issues like this
Organizations can look for missing-authentication risks through:
- Static analysis of administrative routes that lack authentication middleware or guard calls
- Code review checks for authorization decisions based on request parameters
- Route inventories that identify publicly reachable signup and account-management endpoints
- Integration tests covering unauthenticated, authenticated, and unauthorized requests
- Web application logs showing administrative endpoint access without an established authenticated session
- Policy enforcement requiring explicit authentication and authorization controls for sensitive routes
Automated security review tools may help identify routes and code paths where authentication checks are absent or inconsistently applied.
