CWE-437 端点特性的不完整模型 类漏洞列表 3

HTTP request smuggling is an attack against an intermediary such as a proxy. This attack works because the proxy expects the client to parse HTTP headers one way, but the client parses them differently.

Anti-virus products that reside on mail servers can suffer from this issue if they do not know how a mail client will handle a particular attachment. The product might treat an attachment type as safe, not knowing that the client's configuration treats it as executable.
