Vulnerability Description
CVE-2025-32433 is a critical remote code execution vulnerability in Erlang/OTP's SSH server implementation. The flaw exists in the SSH message handling mechanism, allowing attackers to send specially crafted SSH messages that trigger a buffer overflow condition.
The vulnerability requires no authentication and can be exploited remotely over the network. Successful exploitation allows attackers to execute arbitrary code with the privileges of the SSH server process, potentially leading to complete system compromise.
