Live › vulnerability › CVE-2025-32433
Go to dashboardThe Erlang/OTP SSH server accepts SSH protocol messages before authenticating the session, so it can run commands without valid credentials. An unauthenticated remote attacker can execute arbitrary commands on the server, and CISA lists it as actively exploited.
Summary written from the sources below. Check the originals before acting.

Unknown from the sources.
Upgrade Erlang/OTP to a patched release per the vendor advisory, or disable the SSH server if it is not needed; the sources do not name the fixed versions.
Each row is the first time that source carried this signal. The analyst’s rows are its own findings.
Erlang Erlang/OTP SSH server contains a missing authentication for critical function vulnerability. This could allow an attacker to execute arbitrary commands without valid credentials, potentially leading to unauthenticated remote code execution (RCE). By exploiting a flaw in how SSH protocol messages are handled, a malicious actor could gain unauthorized access to affected systems. This vulnerability could affect various products that implement Erlang/OTP SSH server, including—but not limited to—Cisco, NetApp, and SUSE.
CISA required action: Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
