Metadata
Vulnerability Name
SmarterTools SmarterMail Authentication Bypass Using an Alternate Path or Channel Vulnerability
Description
SmarterTools SmarterMail contains an authentication bypass using an alternate path or channel vulnerability in the password reset API.

This could allow an unauthenticated attacker to supply a target administrator username and a new password to reset the account, resulting in full administrative compromise of the SmarterMail instance.
