Multiple buffer overflows in the ISSymbol ActiveX control in ISSymbol.ocx 61.6.0.0 and 301.1009.2904.0 in the ISSymbol virtual machine, as distributed in Advantech Studio 6.1 SP6 61.6.01.05, InduSoft Web Studio before 7.0+SP1, and InduSoft Thin Client 7.0, allow remote attackers to execute arbitrary code via a long (1) InternationalOrder, (2) InternationalSeparator, or (3) LogFileName property value; or (4) a long bstrFileName argument to the OpenScreen method.

AVEVA Software, LLC InduSoft Web Studio prior to Version 8.1 SP3 and InTouch Edge HMI (formerly InTouch Machine Edition) prior to Version 2017 Update. An unauthenticated remote user could use a specially crafted database connection configuration file to execute an arbitrary process on the server machine.

AVEVA Software, LLC InduSoft Web Studio prior to Version 8.1 SP3 and InTouch Edge HMI (formerly InTouch Machine Edition) prior to Version 2017 Update. Code is executed under the program runtime privileges, which could lead to the compromise of the machine.

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.

InduSoft Web Studio versions prior to 8.1 SP2, and InTouch Edge HMI (formerly InTouch Machine Edition) versions prior to 2017 SP2. This vulnerability could allow an unauthenticated user to remotely execute code with the same privileges as that of the InduSoft Web Studio or InTouch Edge HMI (formerly InTouch Machine Edition) runtime.

Absolute path traversal vulnerability in NTWebServer.exe in Indusoft Studio 7.0 and earlier and Advantech Studio 7.0 and earlier allows remote attackers to read arbitrary files via a full pathname in an argument to the sub_401A90 CreateFileW function.

CEServer.exe in the CEServer component in the Remote Agent module in InduSoft Web Studio 6.1 and 7.0 does not require authentication, which allows remote attackers to execute arbitrary code via vectors related to creation of a file, loading a DLL, and process control.

Stack-based buffer overflow in CEServer.exe in the CEServer component in the Remote Agent module in InduSoft Web Studio 6.1 and 7.0 allows remote attackers to execute arbitrary code via a crafted 0x15 (aka Remove File) operation for a file with a long name.

Directory traversal vulnerability in NTWebServer in InduSoft Web Studio 6.1 and 7.x before 7.0+Patch 1 allows remote attackers to execute arbitrary code via an invalid request.

Stack-based buffer overflow in NTWebServer.exe in the test web service in InduSoft NTWebServer, as distributed in Advantech Studio 6.1 and InduSoft Web Studio 7.0, allows remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code via a long request to TCP port 80.
