Nmap NSE net: http-userdir-enum

Published: 2011-06-01 14:32:46
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:L/Au:N/C:P/I:N/A:N

Detection Type:
remote_analysis

Summary:
Attempts to enumerate valid usernames on web servers running with the mod_userdir module or similar enabled. The Apache mod_userdir module allows user-specific directories to be accessed using the http://example.com/~user/ syntax. This script makes http requests in order to discover valid user- specific directories and infer valid usernames. By default, the script will use Nmap's 'nselib/data/usernames.lst'. An HTTP response status of 200 or 403 means the username is likely a valid one and the username will be output in the script results along with the status code (in parentheses). This script makes an attempt to avoid false positives by requesting a directory which is unlikely to exist. If the server responds with 200 or 403 then the script will not continue testing it. SYNTAX: userdir.users: The filename of a username list. limit: The maximum number of users to check. http-max-cache-size: The maximum memory size (in bytes) of the cache. http.pipeline: If set, it represents the number of HTTP requests that'll be pipelined (ie, sent in a single request). This can be set low to make debugging easier, or it can be set high to test how a server reacts (its chosen max is ignored).

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
