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.
