[原文]Interpretation conflict in Fortinet FortiGate 2.8, running FortiOS 2.8MR10 and v3beta, allows remote attackers to bypass the URL blocker via an (1) HTTP request terminated with a line feed (LF) and not carriage return line feed (CRLF) or (2) HTTP request with no Host field, which is still processed by most web servers without violating RFC2616.


[CNNVD]Fortinet FortiGate URL检查过滤绕过漏洞(CNNVD-200512-899)

        Fortinet FortiGate是一款流行的硬件防火墙。
        运行FortiOS 2.8MR10和v3beta的Fortinet FortiGate 2.8版本在处理HTTP请求的URL过滤时存在漏洞。远程攻击者可利用此漏洞绕过检查过滤。如果HTTP请求的每行都以CR而不是CRLF结束的话,或如果HTTP/1.0请求中没有主机字段的话,Fortinet就会无法解析,导致恶意URL绕过Fortinet URL拦截器。
