Technical Details for CVE-2023-48748
Vulnerability Analysis
CVE-2023-48748 is a medium-severity, reflected XSS vulnerability. The vulnerability arises from the improper neutralization of user input that is dynamically included in web pages. This could permit attackers to inject malicious scripts via URLs.
Root Cause
The root cause is the lack of input validation and output encoding within the Salient Core plugin, specifically missing sufficient sanitation for user-supplied strings in page URLs.
Attack Vector
An attacker can exploit this vulnerability remotely by constructing a malicious URL containing script code. When a user clicks the link, the script executes in their browser context.
// Example exploitation code (sanitized)
window.location = "http://victim.com/page?query=<script>alert('XSS')</script>";
Detection Methods for CVE-2023-48748
Indicators of Compromise
- Presence of unusual script tags in URLs
