Name of the Vulnerable Software and Affected Versions
open62541 version 1.5.5
Description
The server-side AddReferences implementation contains an incomplete validation flaw for non-local ExpandedNodeId targets. A remote attacker can send a crafted AddReferencesRequest with an empty
targetServerUri and a non-zero targetNodeId.serverIndex, which causes the target node pointer to remain NULL while execution continues, leading to a null pointer dereference.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
