| Vector | AV:N/AC:L/Au:N/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
node-opcua versions prior to 2.74.0
Description
The issue is related to a Denial of Service (DoS) condition that can be triggered by bypassing limitations for excessive memory consumption. This can be achieved by sending multiple CloseSession requests with the
deleteSubscription parameter set to False. The vulnerability is associated with incorrect cleanup or release of resources, which can be exploited by a remote attacker to cause a service disruption.Recommendations
For versions prior to 2.74.0, update to version 2.74.0 or later to resolve the issue. As a temporary workaround, consider restricting access to the
CloseSession request or setting the deleteSubscription parameter to True to minimize the risk of exploitation.Fix
Resource Exhaustion
