Script `http-open-redirect`

Categories: discovery, intrusive
Download: https://svn.nmap.org/nmap/scripts/http-open-redirect.nse

Script Summary

Spiders a website and attempts to identify open redirects. Open redirects are handlers which commonly take a URL as a parameter and responds with a HTTP redirect (3XX) to the target. Risks of open redirects are described at http://cwe.mitre.org/data/definitions/601.html.

Only open redirects that are directly linked on the target website can be discovered this way. If an open redirector is not linked, it will not be discovered.

Script Arguments

http-open-redirect.maxdepth: the maximum amount of directories beneath the initial url to spider. A negative value disables the limit. (default: 3)
http-open-redirect.maxpagecount: the maximum amount of pages to visit. A negative value disables the limit (default: 20)
http-open-redirect.url: the url to start spidering. This is a URL relative to the scanned host eg. /default.html (default: /)
http-open-redirect.withindomain: only spider URLs within the same domain. This widens the scope from withinhost and can not be used in combination. (default: false)
http-open-redirect.withinhost: only spider URLs within the same host. (default: true)
