CWE-436 (解释冲突) — Vulnerability Class 45

CWE-436, Interpretation Conflict, is a design weakness occurring when two interacting components, such as a client and server or an intermediary proxy, interpret the same input or state differently. This discrepancy typically arises in security appliances like firewalls or anti-virus software that modify traffic based on conflicting expectations of protocol behavior. Attackers exploit this by crafting malicious payloads that trigger divergent interpretations, causing the security device to permit harmful data or the target system to execute unintended actions. To mitigate this risk, developers must ensure consistent parsing logic across all interacting components. Implementing strict, unified protocol standards and rigorous validation checks at every processing stage helps eliminate ambiguity. Additionally, thorough integration testing that simulates edge-case scenarios can reveal interpretation mismatches before deployment, ensuring that all entities in the communication chain process data uniformly and securely.
