Detection Guidance

This vulnerability involves cross site scripting (XSS) in the /inventory/sales_save file of Devs Palace ERP Online up to version 4.0.0. Detection typically involves monitoring HTTP requests to this endpoint for suspicious input patterns that could trigger XSS.

• Using grep on web server logs to find requests to the vulnerable endpoint with suspicious script tags or encoded payloads: grep -iE '(/inventory/sales_save).*(<script|%3Cscript)' /var/log/apache2/access.log
• Using curl to test the endpoint manually with a simple XSS payload: curl -X POST -d 'param=<script>alert(1)</script>' https://yourserver/inventory/sales_save -v
• Using intrusion detection systems (IDS) or web application firewalls (WAF) with rules to detect XSS payloads targeting /inventory/sales_save.
