Vulnerabilities

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.

There is a vulnerability in AVEVA PI Asset Framework Client that could allow malicious code to execute on the PI System Explorer environment under the privileges of an interactive user that was socially engineered to import XML supplied by an attacker.

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.

AVEVA PI Server versions 2023 and 2018 SP3 P05 and prior contain a vulnerability that could allow an unauthenticated user to remotely crash the PI Message Subsystem of a PI Server, resulting in a denial-of-service condition.

An issue was discovered in ExecuteCommand() in AVEVA Edge (formerly InduSoft Web Studio) versions R2020 and prior that allows unauthenticated arbitrary commands to be executed.

This privilege escalation vulnerability, if exploited, cloud allow a local OS-authenticated user with standard privileges to escalate to System privilege on the machine where these products are installed, resulting in complete compromise of the target machine.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of AVEVA Edge 2020 SP2 Patch 0(4201.2111.1802.0000). User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of APP files. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-17212.

The listed versions of AVEVA Plant SCADA and AVEVA Telemetry Server are vulnerable to an improper authorization exploit which could allow an unauthenticated user to remotely read data, cause denial of service, and tamper with alarm states.

AVEVA InTouch Access Anywhere versions 2020 R2 and older are vulnerable to a path traversal exploit that could allow an unauthenticated user with network access to read files on the system outside of the secure gateway web server.

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.

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.

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

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

The vulnerability could expose cleartext credentials from AVEVA InTouch Runtime 2020 R2 and all prior versions (WindowViewer) if an authorized, privileged user creates a diagnostic memory dump of the process and saves it to a non-protected location.

An SQL injection vulnerability exists in the CHaD.asmx web service functionality of eDNA Enterprise Data Historian 3.0.1.2/7.5.4989.33053. Specially crafted SOAP web requests can cause SQL injections resulting in data compromise. Parameter InstanceName in CHaD.asmx is vulnerable to unauthenticated SQL injection attacks.

The IEC870IP driver for AVEVA’s Vijeo Citect and Citect SCADA and Schneider Electric’s Power SCADA Operation has a buffer overflow vulnerability that could result in a server-side crash.

AVEVA Wonderware System Platform 2017 Update 2 and prior uses an ArchestrA network user account for authentication of system processes and inter-node communications. A user with low privileges could make use of an API to obtain the credentials for this account.

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. 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.
