CVE-2019-17123: Egain Mail

High severity, CVSS 7.5. EPSS: 1% chance of exploitation in the next 30 days.

The eGain Web Email API 11+ allows spoofed messages because the fromName and message fields (to /system/ws/v11/ss/email) are mishandled, as demonstrated by fromName header injection with a %0a or %0d character. (Also, the message parameter can have initial HTML comment characters.)
