X Display Manager Control Protocol (XDMCP) |

Checks if XDM has XDMCP protocol enabled Detailed Explanation for this Vulnerability Assessment Summary : XDMCP is running on the remote host. Description : XDMCP permit a Unix user to remotely obtain a graphical X11 login (and therefore act as a local user on the remote host). If a possible hacker gains a valid login and password, he may be able to use this service to gain further access on the remote host. A possible hacker may also use this service to mount a dictionary attack against the remote host to try to log in remotely. Note that XDMCP (the Remote Desktop Protocol) is vulnerable to Man-in-the-middle attacks, making it easy for attackers to steal the credentials of legitimates users by impersonating the XDMCP server. In addition to this, XDMCP is not a ciphered protocol which make it easy for a possible hacker to capture the keystrokes entered by the user. Solution : Disable the XDMCP if you do not use it, and do not permit this service to run across the internet Network Security Threat Level: Low / CVSS Base Score : 1.9 (AV:R/AC:H/Au:NR/C:P/I:N/A:N/B:N) Networks Security ID: Vulnerability Assessment Copyright: This script is Copyright (C) 2002 Pasi Eronen |
