What to do
AI-suggested
1. Immediately restrict access to the import component and search functionality to trusted users only, preferably within a secured network segment. 2. Implement strict input validation and output encoding on all user-supplied data in the search function to neutralize malicious scripts. 3. Employ Content Security Policy (CSP) headers to limit the execution of unauthorized scripts in browsers. 4. Educate users about the risks of interacting with untrusted inputs and the importance of not clicking suspicious links or inputs within the application. 5. Monitor application logs for unusual search queries or error patterns indicative of attempted exploitation. 6. If feasible, disable or limit the import component until an official patch is released. 7. 8. Consider deploying Web Application Firewalls (WAF) with custom rules to detect and block XSS attack patterns targeting the search function.
Description
Cross Site Scripting vulnerability in Martin Kucej i-librarian v.5.11.0 and before allows a local attacker to execute arbitrary code via the search function in the import component.
