CVE-2022-43046 Ordering Management System v1.0 had a XSS vulnerability in the /foms/place-order.php component.

CVE-2022-43046 Ordering Management System v1.0 had a XSS vulnerability in the /foms/place-order.php component.

An attacker can exploit this vulnerability to execute arbitrary script code in the user’s browser session. In order to exploit this vulnerability, an attacker must be able to lure a user to click on a malicious link or open a malicious file.

The following PoC was recorded and uploaded to demonstrate the cross-site scripting vulnerability:

Evasion Techniques:

There are a few techniques that can be employed to prevent XSS attacks. Some of the most common techniques used to protect against XSS include:

Use a different password for each site – By using a different password for each site, an attacker cannot leverage one password to access other accounts.

History/Profile Management – Most web browsers do not store HTTP request information in their memory. By clearing the history or profile of each web browser, an attacker’s XSS attack will no longer be stored in each user’s browser.

Filter/Redirect Invalid Data – Most web applications allow users to input data directly into the application. An attacker can launch an XSS attack on a website by filtering/redirecting invalid data into the application.

Application Whitelisting – By creating an application blacklist, an attacker can launch an XSS attack on a website by submitting application data to the blacklist.

Application Denial of Service – By flooding an application with invalid data, an attacker can launch an XSS attack on a website by flooding the application with invalid data.

Rank Checker Vulnerability

The Rank Checker website was vulnerable to XSS attacks.

Cross-site request forgery (CSRF)

A cross-site request forgery (CSRF) is an attack in which a malicious website tricks a user into performing an unwanted action on a legitimate website by exploiting a vulnerability. The attacker uses the target site's interface to carry out actions on behalf of the user, without their knowledge or consent.

An attacker can exploit this vulnerability to execute arbitrary script code in the user’s browser session. In order to exploit this vulnerability, an attacker must be able to lure a user to click on a malicious link or open a malicious file.

Application Whitelisting

Application whitelisting is a technique by which an application is limiting itself to accept only applications that are specifically authorized. This method can be used to protect against XSS attacks and other web application vulnerabilities. The following code can be used to implement whitelisting:

Vulnerability discovery and exploitation

Exploitation can be achieved by luring a user to click on a malicious link or open a malicious file. In order to exploit this vulnerability, an attacker must be able to lure a user to click on a malicious link or open a malicious file.
