Technical Details & Description:

================================

Multiple classic sql-injection web vulnerabilities has been discovered in the Mult-e-Cart Ultimate v2.4 (v2021) web-application.

The web vulnerability allows remote attackers to inject or execute own sql commands to compromise the database management system.

The vulnerabilities are located in the `id` parameter of the `view` and `update` function. The vulnerable modules are `inventory`,

`customer`, `vendor` and `order`. Remote attackers with a vendor shop account are able to exploit the vulnerable id parameter to

execute malicious sql commands. The request method to inject is get and the attack vector is located on the client-side. The remote

vulnerability is a classic order by sql-injection. The issue is exploitable with one of the two vendor roles or higher privileged

roles like admin.

Exploitation of the remote sql injection vulnerabilities requires no user interaction and a privileged vendor- or admin role user account.

Successful exploitation of the remote sql injection results in database management system, web-server and web-application compromise.

Request Method(s):

[+] GET

Vulnerable Module(s):

[+] inventory/inventory/update

[+] /customer/customer/view

[+] /vendor/vendor/view

[+] /order/sub-order/view-order

Vulnerable Parameter(s):

[+] id

Proof of Concept (PoC):

=======================

The remote sql injection web vulnerabilities can be exploited by remote attackers with privileged backend panel access without user interaction.
