Remediation

Fix status not established

No structured fix or guidance is available here. Check the latest publisher advisory.

What this means

SEPPmail Secure Email Gateway before 15.1.1 allows password recovery for unregistered GINA accounts with empty initial passwords without verifying ownership, permitting a remote unauthenticated attacker to set a new password and authenticate as that account. The attacker must identify such an account. This can prevent the intended recipient from using the account until recovery.

Summarized by @cf/meta/llama-3.3-70b-instruct-fp8-fast. Verify details against the original sources.

Original source description

Read the full publisher description

SEPPmail Secure Email Gateway before 15.1.1 permits password recovery for a created but unregistered GINA account whose initial password is empty without adequately verifying ownership. A remote unauthenticated attacker who identifies such an account can set a new password, authenticate as that account, and prevent the intended recipient from using it until recovery.
