CWE-1390 — Vulnerability Class 62

CWE-1390 represents a critical authentication weakness where the system fails to adequately verify a user’s claimed identity, allowing unauthorized access through insufficient proof mechanisms. Attackers typically exploit this vulnerability by bypassing security controls with minimal effort, often leveraging weak passwords, missing multi-factor authentication, or flawed session management to gain illicit entry. This deficiency enables rapid credential stuffing or brute-force attacks that succeed where robust systems would fail. To mitigate this risk, developers must implement strong, multi-layered authentication protocols, including complex password policies, multi-factor authentication, and adaptive risk-based analysis. By ensuring that identity verification is rigorous and resistant to common bypass techniques, organizations can significantly reduce the attack surface and protect sensitive resources from unauthorized exploitation.
