Synopsis
The remote host may give an attacker information useful for future attacks.
Description
The remote host is running a Lotus Notes 4.6 or 5.x email client. The login dialogue box used by these version of Notes includes a number of security features, including a set of four hieroglyphic characters. The goal of these characters is to increase the difficulty in spoofing the login dialog. An attacker with knowledge of the expected hieroglyphic sequence for a given login may use this dialogue to perform a brute force attack. This will eliminate a number of incorrect passwords, reducing the search space by approximately a factor of two. A conventional brute force attack against the remaining possibilities will then be required.
