Schneider Electric SCADA Expert ClearSCADA Cryptographic Issues

Schneider Electric StruxureWare SCADA Expert ClearSCADA 2010 R3 through 2014 R1 uses the MD5 algorithm for an X.509 certificate, which makes it easier for remote attackers to spoof servers via a cryptographic attack against this algorithm.

Schneider Electric SCADA Expert ClearSCADA Improper Authentication

Schneider Electric StruxureWare SCADA Expert ClearSCADA 2010 R3 through 2014 R1 allows remote attackers to read database records by leveraging access to the guest account.

Schneider Electric SCADA Expert ClearSCADA Cross-site Scripting

Multiple cross-site scripting (XSS) vulnerabilities in Schneider Electric StruxureWare SCADA Expert ClearSCADA 2010 R3 through 2014 R1 allow remote authenticated users to inject arbitrary web script or HTML via unspecified vectors.

Schneider Electric StruxureWare SCADA Expert ClearSCADA Improper Restriction of Operations within the Bounds of a Memory Buffer

The PLC driver in ServerMain.exe in the Kepware KepServerEX 4 component in Schneider Electric StruxureWare SCADA Expert ClearSCADA 2010 R2 build 71.4165, 2010 R2.1 build 71.4325, 2010 R3 build 72.4560, 2010 R3.1 build 72.4644, 2013 R1 build 73.4729, 2013 R1.1 build 73.4832, 2013 R1.1a build 73.4903, 2013 R1.2 build 73.4955, and 2013 R2 build 74.5094 allows remote attackers to cause a denial of service (application crash) via a crafted OPF file (aka project file).

An Inadequate Encryption Strength issue was discovered in Schneider Electric Wonderware InTouch Access Anywhere, version 11.5.2 and prior. The software will connect via Transport Layer Security without verifying the peer's SSL certificate properly.

An Information Exposure issue was discovered in Schneider Electric Wonderware InTouch Access Anywhere, version 11.5.2 and prior. Credentials may be exposed to external systems via specific URL parameters, as arbitrary destination addresses may be specified.

A Cross-Site Request Forgery issue was discovered in Schneider Electric Wonderware InTouch Access Anywhere, version 11.5.2 and prior. The client request may be forged from a different site. This will allow an external site to access internal RDP systems on behalf of the currently logged in user.

Schneider Electric's ClearSCADA versions released prior to August 2017 are susceptible to a memory allocation vulnerability, whereby malformed requests can be sent to ClearSCADA client applications to cause unexpected behavior. Client applications affected include ViewX and the Server Icon.

AVEVA PCS Portal Uncontrolled Search Path Element

AVEVA Software Platform Common Services (PCS) Portal versions 4.5.2, 4.5.1, 4.5.0, and 4.4.6 are vulnerable to DLL hijacking through an uncontrolled search path element, which may allow an attacker control to one or more locations in the search path.

AVEVA System Platform Improper Verification of Cryptographic Signature

AVEVA System Platform versions 2017 through 2020 R2 P01 does not verify, or incorrectly verifies, the cryptographic signature for data.

AVEVA System Platform Origin Validation Error

AVEVA System Platform versions 2017 through 2020 R2 P01 does not properly verify that the source of data or communication is valid.

AVEVA System Platform Path Traversal

AVEVA System Platform versions 2017 through 2020 R2 P01 uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the software does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.

AVEVA System Platform Missing Authentication for Critical Function

AVEVA System Platform versions 2017 through 2020 R2 P01 does not perform any authentication for functionality that requires a provable user identity.

AVEVA System Platform Cleartext Storage of Sensitive Information in Memory

AVEVA System Platform 2020 stores sensitive information in cleartext, which may allow access to an attacker or a low-privileged user.

AVEVA System Platform Uncaught Exception

An exception is thrown from a function in AVEVA System Platform versions 2017 through 2020 R2 P01, but it is not caught, which may cause a denial-of-service condition.

AVEVA InTouch Access Anywhere Exposure of Resource to Wrong Sphere

Windows OS can be configured to overlay a “language bar” on top of any application. When this OS functionality is enabled, the OS language bar UI will be viewable in the browser alongside the AVEVA InTouch Access Anywhere and Plant SCADA Access Anywhere applications. It is possible to manipulate the Windows OS language bar to launch an OS command prompt, resulting in a context-escape from application into OS.

Schneider Electric InduSoft Web Studio before 7.1.3.4 SP3 Patch 4 and InTouch Machine Edition 2014 before 7.1.3.4 SP3 Patch 4 store cleartext OPC User credentials in a configuration file, which allows local users to obtain sensitive information by reading this file.

Schneider Electric InduSoft Web Studio before 7.1.3.4 SP3 Patch 4 and InTouch Machine Edition 2014 before 7.1.3.4 SP3 Patch 4 transmit cleartext credentials, which allows remote attackers to obtain sensitive information by sniffing the network.

Schneider Electric InduSoft Web Studio before 7.1.3.4 SP3 Patch 4 and InTouch Machine Edition 2014 before 7.1.3.4 SP3 Patch 4 provide an HMI user interface that lists all valid usernames, which makes it easier for remote attackers to obtain access via a brute-force password-guessing attack.

Schneider Electric InduSoft Web Studio before 7.1.3.4 SP3 Patch 4 and InTouch Machine Edition 2014 before 7.1.3.4 SP3 Patch 4 rely on a hardcoded cleartext password to control read access to Project files and Project Configuration files, which makes it easier for local users to obtain sensitive information by discovering this password.
