45 vulnerabilities classified as CWE-696 (不正确的行为次序). AI Chinese analysis included.
CWE-696 represents a logical flaw where a software component executes related operations in an incorrect sequence, leading to unintended security vulnerabilities. This weakness typically arises when developers fail to recognize that the order of actions is critical for maintaining system integrity. Attackers exploit this by manipulating the timing or sequence of inputs to trigger race conditions, bypass authentication checks before validation occurs, or cause resource exhaustion before cleanup routines execute. For instance, checking permissions after opening a file handle allows unauthorized access to sensitive data. To prevent such errors, developers must rigorously map out dependency graphs for all critical workflows, ensuring that security controls, such as validation and authorization, are strictly enforced before any state-changing operations. Comprehensive code reviews and formal verification methods further help identify and correct these sequencing defects before deployment.
