AI-suggested
- Restrict QRadar web UI access to trusted and minimal user groups, enforcing the principle of least privilege to limit who can inject malicious scripts.
- Implement strict input validation and sanitization on all user inputs within the QRadar interface, if possible via configuration or custom rules.
- Monitor web UI logs and user activity for unusual behavior indicative of XSS exploitation attempts.
- Employ web application firewalls (WAFs) with rules designed to detect and block XSS payloads targeting QRadar interfaces.
- Isolate QRadar management interfaces from general network access, using VPNs or jump hosts to reduce exposure.
- Stay updated with IBM security advisories and apply patches or fixes as soon as they become available.
- Educate users with access to QRadar about the risks of XSS and encourage reporting of suspicious UI behavior.
- Consider deploying Content Security Policy (CSP) headers if configurable to reduce the impact of injected scripts.
Description
IBM QRadar SIEM 7.5 through 7.5.0 Update Pack 13 Independent Fix 02 is vulnerable to stored cross-site scripting. This vulnerability allows an authenticated user to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session.
