An OPC UA server running on the remote host is affected by at least one of the following vulnerabilities :
A stack-based overflow vulnerability exists in the PTC ThingWorx Edge server due to improper validation of user-supplied data when decoding OPC UA strings. An unauthenticated, remote attacker can exploit this, via a specially crafted message, to cause a denial of service condition or the execution of arbitrary code.
(CVE-2020-27265)
A heap-based overflow vulnerability exists in the PTC ThingWorx Edge server when decoding OPC UA strings. An unauthenticated, remote attacker can exploit this to crash the server and potentially leak data. (CVE-2020-27263)
A use-after-free vulnerability exists in the PTC Kepware KEPServerEX server. An unauthenticated, remote attacker can exploit this to crash the server. (CVE-2020-27267)
Note that this plugin may not detect all affected devices due to the variety of affected products from multiple vendors.
