SMTP Header Injection in VMware vCenter Scheduled Task Notifications
CVE-2025-41250 is a high-severity SMTP header injection vulnerability in VMware vCenter Server affecting the scheduled task email notification mechanism. According to the provided content, vCenter incorporates user-controlled input from scheduled task-related fields into outbound email headers without sufficient sanitization. An authenticated attacker with non-administrative privileges who has permission to create or modify scheduled tasks can inject carriage return/line feed (CRLF) sequences into relevant fields such as a task name or description, causing additional SMTP headers to be inserted or existing headers to be altered in notification emails generated by vCenter. This enables manipulation of the structure and content of scheduled task notification emails.
