DNP3Driver.exe in the DNP3 driver in Schneider Electric ClearSCADA 2010 R2 through 2010 R3.1 and SCADA Expert ClearSCADA 2013 R1 through 2013 R1.2 allows remote attackers to cause a denial of service (resource consumption) via IP packets containing errors that trigger event-journal messages.

The vulnerability, if exploited, could allow an unauthenticated miscreant to perform operations intended only for Simulator Instructor or Simulator Developer (Administrator) roles, resulting in privilege escalation with potential for modification of simulation parameters, training configuration, and training records.

The affected products are vulnerable to an uncaught exception that could allow an unauthenticated attacker to remotely crash core PI services resulting in a denial-of-service.

The vulnerability, if exploited, could allow an attacker with Event Log Reader (S-1-5-32-573) privileges to obtain proxy details, including URL and proxy credentials, from the PI to CONNECT event log files. This could enable unauthorized access to the proxy server.

The vulnerability, if exploited, could allow an unauthenticated miscreant to achieve remote code execution under OS system privileges of “taoimr” service, potentially resulting in complete compromise of the  model application server.

The vulnerability, if exploited, could allow an authenticated miscreant (Process Optimization Standard User) to tamper with queries in Captive Historian and achieve code execution under SQL Server administrative privileges, potentially resulting in complete compromise of the SQL Server.

The vulnerability, if exploited, could allow an authenticated miscreant (OS standard user) to tamper with TCL Macro scripts and escalate privileges to OS system, potentially resulting in complete compromise of the model application server.

The vulnerability, if exploited, could allow an authenticated miscreant (OS Standard User) to tamper with Process Optimization project files, embed code, and escalate their privileges to the identity of a victim user who subsequently interacts with the project files.

The vulnerability, if exploited, could allow an authenticated miscreant (Process Optimization Designer User) to embed OLE objects into graphics, and escalate their privileges to the identity of a victim user who subsequently interacts with the graphical elements.

The vulnerability, if exploited, could allow an authenticated miscreant (OS Standard User) to trick Process Optimization services into loading arbitrary code and escalate privileges to OS System, potentially resulting in complete compromise of the Model Application Server.

The Process Optimization application suite leverages connection channels/protocols that by-default are not encrypted and could become subject to hijacking or data leakage in certain man-in-the-middle or passive inspection scenarios.

The vulnerability, if exploited, could allow a miscreant with read access to Edge Project files or Edge Offline Cache files to reverse engineer Edge users' app-native or Active Directory passwords through computational brute-forcing of weak hashes.

The vulnerability, if exploited, could allow an authenticated miscreant (with privilege of "aaConfigTools") to tamper with App Objects' help files and persist a cross-site scripting (XSS) injection that when executed by a victim user, can result in horizontal or vertical escalation of privileges. The vulnerability can only be exploited during config-time operations within the IDE component of Application Server. Run-time components and operations are not affected.

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.

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 2010 R3 through 2014 R1 allows remote attackers to read database records by leveraging access to the guest account.

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

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

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

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.

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.

The vulnerability, if exploited, could allow a malicious entity with access to the file system to achieve arbitrary code execution and privilege escalation by tricking AVEVA Edge to load an unsafe DLL.
