# 易受预身份验证RCE影响的Erlang/OTP SSH
## 漏洞概述
Erlang/OTP 是一组用于 Erlang 编程语言的库。在某些版本中，SSH 服务器允许未经认证的远程代码执行（RCE）。
## 影响版本
- OTP-27.3.3 之前的所有版本
- OTP-26.2.5.11 之前的所有版本
- OTP-25.3.2.20 之前的所有版本
## 漏洞细节
通过利用 SSH 协议消息处理中的漏洞，恶意行为者可以在无需有效凭据的情况下获取对受影响系统的未经授权的访问并执行任意命令。
## 影响
攻击者可以进行未经认证的远程代码执行（RCE），从而导致系统受损。此问题已在版本 OTP-27.3.3、OTP-26.2.5.11 和 OTP-25.3.2.20 中修复。
## 临时解决方法
禁用 SSH 服务器或使用防火墙规则阻止访问。

| 2 | Erlang/OTP is a set of libraries for the Erlang programming language. Prior to versions OTP-27.3.3, OTP-26.2.5.11, and OTP-25.3.2.20, a SSH server may allow an attacker to perform unauthenticated remote code execution (RCE). By exploiting a flaw in SSH protocol message handling, a malicious actor could gain unauthorized access to affected systems and execute arbitrary commands without valid credentials. | https://github.com/projectdiscovery/nuclei-templates/blob/main/code/cves/2025/CVE-2025-32433.yaml | POC详情 |
