Security researchers have discovered a stored Cross-site Scripting (XSS) vulnerability, labeled as CVE-2023-2332, in pimcore/pimcore versions 10.5.19. Pimcore, an open-source platform and content management system, is widely used by businesses for managing their digital assets. The vulnerability is present in the Conditions tab of Pricing Rules and can pose a severe threat to both users and organizations. In this post, we will discuss the details of this vulnerability, including how it works, its impact, and the steps you should take to mitigate the risk.
Vulnerability Details
The CVE-2023-2332 vulnerability specifically targets the From and To fields located in the Date Range section of the Conditions tab in Pricing Rules. An attacker can exploit this vulnerability by injecting malicious scripts into these fields. When a user views the affected page, the attacker's code executes in the user's browser. This can lead to severe consequences, such as stealing cookies, redirecting users to malicious websites, or even taking over the vulnerable application.
The following code snippet demonstrates the malicious script injection
<script>alert(document.cookie)</script>
Once the above script is injected into the From or To fields of the Date Range section and a user visits the affected page, an alert will pop up on the screen, displaying the user's cookies.
