Insecure PHP deserialization issue in GravityZone Console (VA-12634)

A vulnerability in the sendMailFromRemoteSource method in Emails.php  as used in BItdefender GravityZone Console unsafely uses php unserialize() on user-supplied input without validation. By crafting a malicious serialized payload, an attacker can trigger PHP object injection, perform a file write, and gain arbitrary command execution on the host system.
