    Denial of Service (DoS)

    node-opcua is an implementation of a OPC UA stack fully written in javascript and nodejs

    Affected versions of this package are vulnerable to Denial of Service (DoS) due to a missing limitation on the number of received chunks - per single session or in total for all concurrent sessions.

    An attacker can exploit this vulnerability by sending an unlimited number of huge chunks (e.g. 2GB each) without sending the Final closing chunk.

    How to fix Denial of Service (DoS)?

    Upgrade node-opcua to version 2.74.0 or higher.

    <2.74.0

    How to fix Denial of Service (DoS)?

    Upgrade node-opcua to version 2.74.0 or higher.
