CVE-2018-17916 Information

Description

InduSoft Web Studio versions prior to 8.1 SP2 and InTouch Edge HMI (formerly InTouch Machine Edition) versions prior to 2017 SP2. A remote attacker could send a carefully crafted packet to 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 InduSoft Web Studio 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 InduSoft Web Studio or InTouch Edge HMI server machine.
