Erlang Erlang/OTP SSH Server Missing Authentication for Critical Function Vulnerability (CVE-2025-32433)
Severity: critical · Patch status: patched · Since 2025-06-09 · CVE-2025-32433
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 added CVE-2025-32433 to its Known Exploited Vulnerabilities catalog on Jun 9, 2025, which means attackers are exploiting it in the wild.
What to do
- Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
- US federal agencies must remediate by Jun 30, 2025 (BOD 22-01); treat that as the outer limit.
