Vulnerability Title
node-opcua: Unbounded nonce cache enables unauthenticated heap exhaustion DoS
Vulnerability Description
node-opcua is an OPC UA implementation for TypeScript and Node.js. Prior to 2.166.0, the process-global g_alreadyUsedNonce cache used by nonceAlreadyBeenUsed in packages/node-opcua-secure-channel/source/server/server_secure_channel_layer.ts records nonces from OpenSecureChannelRequest and CreateSession without expiration or a size limit. An unauthenticated remote attacker can repeatedly create sessions with unique nonces, causing entries to persist after session expiry and accumulate across connection cycles even when maxSessions=10 limits concurrent sessions. The resulting unbounded heap growth can exhaust the default Node.js heap and crash the node-opcua server process. This issue is fixed in version 2.166.0.

node-opcua 资源管理错误漏洞
Vulnerability Description
node-opcua是node-opcua组织的一款实现工业网络设备数据交换与服务器端协议通信的软件开发组件。 node-opcua 2.166.0之前版本存在资源管理错误漏洞,该漏洞源于nonceAlreadyBeenUsed使用的进程全局g_alreadyUsedNonce缓存记录OpenSecureChannelRequest和CreateSession的随机数时没有过期时间或大小限制,未经身份验证的远程攻击者可重复创建带唯一随机数的会话,导致条目在会话过期后仍持续存在并跨连接周期累积,造成无限制的
