tomcatWarDeployer

Strumento di penetration testing per il deploy automatico di WAR su Apache Tomcat e compromissione.

Cos'è?

Questo è uno strumento di penetration testing progettato per sfruttare le credenziali di Apache Tomcat al fine di generare e distribuire automaticamente una backdoor JSP, invocarla successivamente e fornire una shell comoda (tramite GUI web, porta di ascolto collegata sulla macchina remota o come payload TCP inverso che si connette all'avversario).

In pratica, genera al volo un pacchetto WAR di backdoor JSP e lo distribuisce nell'Apache Tomcat Manager Application, utilizzando credenziali di autenticazione HTTP valide fornite dal penetration tester (o personalizzate, alla fine, amiamo tutti tomcat:tomcat).

Lo strumento offre un paio di funzionalità utili: logica di ricerca del pannello di amministrazione, supporto per il problema di doppia codifica CVE-2007-1860, gestione CSRF nei Tomcat più recenti.

Utilizzo

Semplice come fornire l'indirizzo del server con la porta, come coppia IP:PORTA. Ecco l'aiuto:

Penetration Testing utility aiming at presenting danger of leaving Tomcat misconfigured.
    
Usage: tomcatWarDeployer.py [options] server

  server    Specifies server address. Please also include port after colon.

Options:
  -h, --help            show this help message and exit

  General options:
    -v, --verbose       Verbose mode.
    -s, --simulate      Simulate breach only, do not perform any offensive
                        actions.
    -G OUTFILE, --generate=OUTFILE
                        Generate JSP backdoor only and put it into specified
                        outfile path then exit. Do not perform any
                        connections, scannings, deployment and so on.
    -U USER, --user=USER
                        Tomcat Manager Web Application HTTP Auth username.
                        Default="tomcat"
    -P PASS, --pass=PASS
                        Tomcat Manager Web Application HTTP Auth password.
                        Default="tomcat"

  Connection options:
    -H RHOST, --host=RHOST
                        Remote host for reverse tcp payload connection. When
                        specified, RPORT must be specified too. Otherwise,
                        bind tcp payload will be deployed listening on 0.0.0.0
    -p PORT, --port=PORT
                        Remote port for the reverse tcp payload when used with
                        RHOST or Local port if no RHOST specified thus acting
                        as a Bind shell endpoint.
    -u URL, --url=URL   Apache Tomcat management console URL. Default:
                        /manager/
    -t TIMEOUT, --timeout=TIMEOUT
                        Speciifed timeout parameter for socket object and
                        other timing holdups. Default: 10

  Payload options:
    -R APPNAME, --remove=APPNAME
                        Remove deployed app with specified name. Can be used
                        for post-assessment cleaning
    -X PASSWORD, --shellpass=PASSWORD
                        Specifies authentication password for uploaded shell,
                        to prevent unauthenticated usage. Default: randomly
                        generated. Specify "None" to leave the shell
                        unauthenticated.
    -T TITLE, --title=TITLE
                        Specifies head>title for uploaded JSP WAR payload.
                        Default: "JSP Application"
    -n APPNAME, --name=APPNAME
                        Specifies JSP application name. Default: "jsp_app"
    -x, --unload        Unload existing JSP Application with the same name.
                        Default: no.
    -C, --noconnect     Do not connect to the spawned shell immediately. By
                        default this program will connect to the spawned
                        shell, specifying this option let's you use other
                        handlers like Metasploit, NetCat and so on.
    -f WARFILE, --file=WARFILE
                        Custom WAR file to deploy. By default the script will
                        generate own WAR file on-the-fly.
