Installation

First make sure you're on Python 2.7/3.4 or higher. Then run the command below to install ACSTIS.

$ pip install https://github.com/tijme/angularjs-csti-scanner/archive/master.zip

Usage

Scan a single URL

acstis -d "https://finnwea.com/some/page/?category=23"

Scan a single URL (and verify that the alert pops)

acstis -vp -d "https://finnwea.com/some/page/?category=23"

Scan an entire domain

acstis -c -d "https://finnwea.com/"

Scan an entire domain (and stop if a vulnerability was found)

acstis -c -siv -d "https://finnwea.com/"

Trust the given certificate

acstis -d "https://finnwea.com/some/page/?category=23" -tc "/Users/name/Desktop/cert.pem"

All command line options

usage: acstis [-h] -d DOMAIN [-c] [-vp] [-av ANGULAR_VERSION] [-vrl VULNERABLE_REQUESTS_LOG] [-siv] [-pmm] [-sos] [-soh] [-sot] [-md MAX_DEPTH] [-mt MAX_THREADS] [-iic] [-tc TRUSTED_CERTIFICATES]

required arguments:
   -d DOMAIN, --domain DOMAIN                                                       the domain to scan (e.g. finnwea.com)

optional arguments:
   -h, --help                                                                       show this help message and exit
   -c, --crawl                                                                      use the crawler to scan all the entire domain
   -vp, --verify-payload                                                            use a javascript engine to verify if the payload was executed (otherwise false positives may occur)
   -av ANGULAR_VERSION, --angular-version ANGULAR_VERSION                           manually pass the angular version (e.g. 1.4.2) if the automatic check doesn't work
   -vrl VULNERABLE_REQUESTS_LOG, --vulnerable-requests-log VULNERABLE_REQUESTS_LOG  log all vulnerable requests to this file (e.g. /var/logs/acstis.log or urls.log)
   -siv, --stop-if-vulnerable                                                       (crawler option) stop scanning if a vulnerability was found
   -pmm, --protocol-must-match                                                      (crawler option) only scan pages with the same protocol as the startpoint (e.g. only https)
   -sos, --scan-other-subdomains                                                    (crawler option) also scan pages that have another subdomain than the startpoint
   -soh, --scan-other-hostnames                                                     (crawler option) also scan pages that have another hostname than the startpoint

   -md MAX_DEPTH, --max-depth MAX_DEPTH                                             (crawler option) the maximum search depth (default is unlimited)
