Vulnerability from gsd - Updated: 2023-12-13 01:19
Details
This vulnerability allows remote attackers to create a denial-of-service condition on affected installations of Unified Automation OPC UA C++ Demo Server 1.7.6-537 [with vendor rollup]. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of certificates. A crafted certificate can force the server into an infinite loop. An attacker can leverage this vulnerability to create a denial-of-service condition on the system. Was ZDI-CAN-17203.
