The login functionality of the web server in affected devices does not normalize the response times of login attempts. An unauthenticated remote attacker could exploit this side-channel information to distinguish between valid and invalid usernames.

The web server of affected devices do not properly authenticate user request to the '/ClientArea/RuntimeInfoData.mwsl' endpoint. This could allow an unauthenticated remote attacker to gain knowledge about current actual and configured maximum cycle times as well as about configured maximum communication load.

The web server of affected devices does not properly validate input that is used for a user redirection. This could allow an attacker to make the server redirect the legitimate user to an attacker-chosen URL. For a successful exploit, the legitimate user must actively click on an attacker-crafted link.

Affected devices improperly handle specially crafted packets sent to port 102/tcp. This could allow an attacker to create a denial of service condition. A restart is needed to restore normal operations.

The OPC UA implementations (ANSI C and C++) in affected products contain an integer overflow vulnerability that could cause the application to run into an infinite loop during certificate validation. This could allow an unauthenticated remote attacker to create a denial of service condition by sending a specially crafted certificate.

Affected devices don't process correctly certain special crafted packets sent to port 102/tcp, which could allow an attacker to cause a denial of service in the device.

Affected devices don't process correctly certain special crafted packets sent to port 102/tcp, which could allow an attacker to cause a denial of service in the device.

The login endpoint /FormLogin in affected web services does not apply proper origin checking. This could allow authenticated remote attackers to track the activities of other users via a login cross-site request forgery attack.
