CWE-150 (转义、元或控制序列转义处理不恰当) — Vulnerability Class 38

CWE-150 represents a critical input validation weakness where software fails to properly sanitize special characters before passing data to a downstream component. This flaw typically allows attackers to inject malicious escape, meta, or control sequences, such as HTML tags or SQL commands, which the receiving system interprets as executable instructions rather than literal text. Exploitation often leads to severe consequences like cross-site scripting, command injection, or data corruption, depending on the context of the downstream processor. To mitigate this risk, developers must implement rigorous input validation and output encoding strategies. By strictly neutralizing potentially dangerous characters through context-aware encoding techniques, such as HTML entity encoding or parameterized queries, developers ensure that user-supplied data remains inert, thereby preventing the unintended execution of injected payloads within the application environment.
