Apache Remote Username Enumeration Vulnerability |
||
|
Checks for the error codes returned by Apache when requesting a non-existant user name Detailed Explanation for this Vulnerability Assessment Summary : The remote Apache server can be used to guess the existence of a given user name on the remote host. Description : When configured with the 'UserDir' option, requests to URLs containing a tilde followed by a username will redirect the user to a given subdirectory in the user home. For instance, by default, requesting /~root/ displays the HTML contents from /root/public_html/. If the username requested does not exist, then Apache will reply with a different error code. Therefore, a possible hacker may exploit this vulnerability to guess the existence of a given user name on the remote host. Solution : In httpd.conf, set the 'UserDir' to 'disabled'. Network Security Threat Level: Low / CVSS Base Score : 2 (AV:R/AC:L/Au:NR/C:P/A:N/I:N/B:N) Networks Security ID: 3335 Vulnerability Assessment Copyright: This script is Copyright (C) 2005-2006 Tenable Network Security |
