CVE-2024-55929Network attack vector

Unauthenticated email impersonation via forged sender headers

Published Jan 23, 2025 · Updated Feb 24, 2025

Mail spoofing in Xerox Workplace Suite before 5.6.701.9 allows remote attackers to forge sender headers in outbound email. Xerox identifies the behavior only as forged email headers and has not published the affected handler or the validation operation it omits. No authentication or user interaction is required; successful exploitation makes generated messages appear to originate from trusted senders.
