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.

AVEVA InduSoft Web Studio v8.1 and v8.1SP1, and InTouch Machine Edition v2017 8.1 and v2017 8.1 SP1 a remote user 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.

Systems with microprocessors utilizing speculative execution and speculative execution of memory reads before the addresses of all prior memory writes are known may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis, aka Speculative Store Bypass (SSB), Variant 4.

A remote attacker could send a carefully crafted packet in InduSoft Web Studio v8.1 and prior versions, and/or InTouch Machine Edition 2017 v8.1 and prior versions during a tag, alarm, or event related action such as read and write, which may allow remote code execution.

A Stack-based Buffer Overflow issue was discovered in Schneider Electric InduSoft Web Studio v8.0 SP2 Patch 1 and prior versions, and InTouch Machine Edition v8.0 SP2 Patch 1 and prior versions. The stack-based buffer overflow vulnerability has been identified, which may allow remote code execution with high privileges.

A Missing Authentication for Critical Function issue was discovered in Schneider Electric InduSoft Web Studio v8.0 SP2 or prior, and InTouch Machine Edition v8.0 SP2 or prior. InduSoft Web Studio provides the capability for an HMI client to trigger script execution on the server for the purposes of performing customized calculations or actions. A remote malicious entity could bypass the server authentication and trigger the execution of an arbitrary command. The command is executed under high privileges and could lead to a complete compromise of the server.

An Incorrect Default Permissions issue was discovered in Schneider Electric Wonderware InduSoft Web Studio v8.0 Patch 3 and prior versions. Upon installation, Wonderware InduSoft Web Studio creates a new directory and two files, which are placed in the system's path and can be manipulated by non-administrators. This could allow an authenticated user to escalate his or her privileges.

Schneider Electric InduSoft Web Studio before 8.0 allows remote attackers to execute arbitrary code or cause a denial of service (unhandled runtime exception and application crash) via a crafted Indusoft Project file.

The Remote Agent component in Schneider Electric InduSoft Web Studio before 8.0 allows remote attackers to execute arbitrary code via unspecified vectors, aka ZDI-CAN-2649.

Schneider Electric InduSoft Web Studio before 7.1.3.5 Patch 5 and Wonderware InTouch Machine Edition through 7.1 SP3 Patch 4 use cleartext for project-window password storage, which allows local users to obtain sensitive information by reading a file.
