How CVE-2025-22221 Works
VMware Aria Operations for Logs is vulnerable to stored cross-site scripting (XSS) due to insufficient input sanitization in the Agent Configuration delete action. An attacker with admin privileges injects a malicious script payload into the configuration. When another administrator performs a delete operation, the script executes in their browser session, potentially leading to session hijacking, data theft, or privilege escalation. The attack persists because the payload is stored server-side and triggers upon interaction with the compromised component.

grep -r "unsanitized" /opt/vmware/logs/webui/
Mitigation:
1. Input Sanitization:
function sanitize(input) {
return input.replace(/<script.?>.?<\/script>/gi, '');
