Threat Score
A remote code execution vulnerability in Zimbra mail servers can be triggered by malformed emails; Proofpoint observed opportunistic exploit attempts and a public proof-of-concept, but exploitation appears limited and not reliably leading to mass infections. Defenders should monitor for malformed To/CC fields and unusual outbound connections from Zimbra appliances.
