In SalonERP version 3..2, there is a critical security vulnerability (CVE-2022-42753) that allows an external attacker to steal cookies of arbitrary users, due to insufficient validation of the page parameter against Cross-Site Scripting (XSS) attacks. This blog post will detail the exploit, outline a code snippet to demonstrate the vulnerability, and provide a link to the original references. Stay with me as we dive deep into this vulnerability!

Vulnerability Details

SalonERP is management software that helps salon businesses automate their daily operations. However, the application has a security loophole in its page parameter that allows an attacker to inject malicious code via Cross-Site Scripting. As a result, an attacker can steal a user's session cookie, potentially gaining unauthorized access to their account.

A successful exploit of this vulnerability can lead to severe consequences for SalonERP users such as unauthorized access to private data, exposure of sensitive information, and potentially leading to further compromise of the entire salon management system.

Exploiting the Vulnerability

In order to exploit this vulnerability, an attacker can craft a malicious URL containing a payload utilizing the XSS vulnerability in the page parameter. Once a user clicks on that link, the payload is executed in their browser, and their cookie is sent to the attacker's web server. Here's an example of a payload that demonstrates the vulnerability:


When a user visits this URL, the injected JavaScript code will run and send their cookie to the attacker's website ( while logging their cookie information in a log file on the attacker's server.

It is worth noting that the attacker needs to convince or social engineer the target user into clicking the malicious link for the exploit to work.

The initial report of this vulnerability (CVE-2022-42753) can be found at the following link from the official National Vulnerability Database:

Additionally, the vulnerability was first found and submitted by a security researcher on the CVE database:


To protect against this vulnerability, SalonERP users should update their software to the latest version. Also, it is essential for developers to sanitize and validate user input, especially within URI elements prone to XSS attacks.

Furthermore, users should be cautious when clicking on links from unknown sources, and organizations should conduct regular security awareness training to educate employees on the dangers of phishing and social engineering attacks.


The CVE-2022-42753 shows that even modern applications like SalonERP 3..2, designed to improve your business's efficiency, can contain security vulnerabilities. It is crucial to stay informed about the latest software updates and security patches to minimize the risk of exploitation. By practicing secure coding techniques, conducting regular security assessments, and providing ongoing training for developers and users, you can further protect your organization from threats posed by XSS vulnerabilities.
