What to do
AI-suggested
- Immediately restrict access to the import component and search functionality to trusted users only, preferably within a secured network segment.
- Implement strict input validation and output encoding on all user-supplied data in the search function to neutralize malicious scripts.
- Employ Content Security Policy (CSP) headers to limit the execution of unauthorized scripts in browsers.
- Educate users about the risks of interacting with untrusted inputs and the importance of not clicking suspicious links or inputs within the application.
- Monitor application logs for unusual search queries or error patterns indicative of attempted exploitation.
- If feasible, disable or limit the import component until an official patch is released.
- 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.
