Name of the Vulnerable Software and Affected Versions InduSoft Web Studio versions prior to 8.1 SP2 InTouch Edge HMI versions prior to 2017 SP2

Description A remote attacker could exploit a stack-based buffer overflow vulnerability during tag, alarm, or event related actions, such as read and write, with potential for code to be executed. If remote communication security was not enabled, or a password was left blank, a remote user could send a carefully crafted packet to invoke an arbitrary process, with potential for code to be executed. The code would be executed under the privileges of the InduSoft Web Studio or InTouch Edge HMI runtime and could lead to a compromise of the server machine.

Recommendations For InduSoft Web Studio versions prior to 8.1 SP2, update to version 8.1 SP2 or later to resolve the issue. For InTouch Edge HMI versions prior to 2017 SP2, update to version 2017 SP2 or later to resolve the issue. As a temporary workaround, consider enabling remote communication security and setting a strong password to minimize the risk of exploitation.
