Script Description
The domcon-brute.nse script performs brute force password auditing against the Lotus Domino Console.
Domcon-brute NSE Script Arguments
This is a full list of arguments supported by the domcon-brute.nse script:
creds.globalCredentials to be returned by Credentials.getCredentials regardless of the service.
creds.[service]Credentials to be returned by Credentials.getCredentials for [service]. E.g. creds.http=admin:password
passdbThe filename of an alternate password database. Default: nselib/data/passwords.lst
unpwdb.passlimit
The maximum number of passwords passwords
will return (default unlimited).
The maximum amount of time that any iterator will run before stopping. The value is in seconds by default and you can follow it with ms
, s
, m
, or h
for milliseconds, seconds, minutes, or hours. For example, unpwdb.timelimit=30m
or unpwdb.timelimit=.5h
for 30 minutes. The default depends on the timing template level (see the module description). Use the value 0
to disable the time limit.
The maximum number of usernames usernames
will return (default unlimited).
The filename of an alternate username database. Default: nselib/data/usernames.lst
brute.credfileA file containing username and password pairs delimited by '/'
brute.delayThe number of seconds to wait between guesses (default: 0)
brute.emptypassGuess an empty password for each user (default: false)
brute.firstonlyStop guessing after first password is found (default: false)
brute.guessesThe number of guesses to perform against each account. (default: 0 (unlimited)). The argument can be used to prevent account lockouts.
brute.modeCan be user, pass or creds and determines what mode to run the engine in.
- user - the unpwdb library is used to guess passwords, every password Password is tried for each user. (The user iterator is in the outer loop)
- pass - the unpwdb library is used to guess passwords, each password Is tried for every user. (The password iterator is in the outer loop)
- creds - a set of credentials (username and password pairs) are Guessed against the service. This allows for lists of known or common username and password combinations to be tested. If no mode is specified and the script has not added any custom iterator the pass mode will be enabled.
Iterate over passwords only for services that provide only a password for authentication. (default: false)
brute.retriesThe number of times to retry if recoverable failures occur. (default: 2)
brute.startThe number of threads the engine will start with. (default: 5).
brute.threadsThe number of initial worker threads, the number of active threads will be automatically adjusted.
brute.uniqueMake sure that each password is only guessed once (default: true)
brute.useraspassGuess the username as password for each user (default: true)
creds.[service]Credentials to be returned by Credentials.getCredentials for [service]. E.g. creds.http=admin:password

To use these script arguments, add them to the Nmap command line using the --script-args arg1=value,[arg2=value,..]
syntax. For example:
nmap --script=domcon-brute --script-args creds.global=value,creds.\[service]=value <target>

There is no sample XML output for this module. However, by providing the -oX <file>
