# CVE-2023-51300  
  
Descriptions:  
PHPJabbers Hotel Booking System v4.0 is vulnerable to Multiple Stored  
Cross-Site Scripting. Multiple Stored XSS is a type of security  
vulnerability that occurs when an application or website allows an  
attacker to inject malicious scripts into the content that is  
permanently stored on the server. Unlike reflected XSS, where the  
malicious script is embedded in a URL and executed immediately, stored  
XSS involves the persistent storage of the malicious script on the  
target server, waiting for unsuspecting users to access the  
compromised content.  
  
Steps to Reproduce:  
1. Login your panel.  
2. Vulnerable parameters are "name, plugin_sms_api_key,  
plugin_sms_country_code, title, plugin_sms_api_key".  
3. Go to System Menu then click SMS Settings.  
4. Then use any XSS Payload in "SMS API Key", "Default Country Code"  
input field and Save.  
5. You will see popup.
