Angular Client-Side Template Injection Scanner

ACSTIS helps you to scan certain web applications for AngularJS Client-Side Template Injection (sometimes referred to as CSTI, sandbox escape or sandbox bypass). It supports scanning a single request but also crawling the entire web application for the AngularJS CSTI vulnerability.

Table of contents


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

$ pip install


Scan a single URL

acstis -d ""

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

acstis -vp -d ""

Scan an entire domain

acstis -c -d ""

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

acstis -c -siv -d ""

Trust the given certificate

acstis -d "" -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.

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
   -sot, --scan-other-tlds                                                          (crawler option) also scan pages that have another tld than the startpoint
   -md MAX_DEPTH, --max-depth MAX_DEPTH                                             (crawler option) the maximum search depth (default is unlimited)
   -mt MAX_THREADS, --max-threads MAX_THREADS                                       (crawler option) the maximum amount of simultaneous threads to use (default is 20)
   -iic, --ignore-invalid-certificates                                              (crawler option) ignore invalid ssl certificates
   -tc TRUSTED_CERTIFICATES, --trusted-certificates TRUSTED_CERTIFICATES            (crawler option) trust this CA_BUNDLE file (.pem) or directory with certificates

These options are not implemented in the command line interface of ACSTIS. Please download the script and extend it with one or more of the following code snippets. You can paste these code snippets in the main() method of the script.

Please note: if you use the file make sure you call python [your arguments] instead of acstis [your arguments].
