A Permissions, Privileges, and Access Controls issue was discovered in OSIsoft PI Web API versions 2017 R2 and prior. Privileges may be escalated, giving attackers access to the PI System via the service account.

An Information Exposure issue was discovered in OSIsoft PI Vision versions 2017 and prior. The server response header and referrer-policy response header each provide unintended information disclosure.

An issue was discovered in OSIsoft PI Coresight 2016 R2 and earlier versions, and PI Web API 2016 R2 when deployed using the PI AF Services 2016 R2 integrated install kit. An information exposure through server log files vulnerability has been identified, which may allow service account passwords to become exposed for the affected services, potentially leading to unauthorized shutdown of the affected PI services as well as potential reuse of domain credentials.

A Prototype Pollution vulnerability was found in jquery. Untrusted JSON passed to the extend function could lead to modifying objects up the prototype chain, including the global Object. A crafted JSON object passed to a vulnerable method could lead to denial of service or data injection, with various consequences.

An issue was discovered in OSIsoft PI Web API 2015 R2 (Version 1.5.1). There is a weakness in this product that may allow an attacker to access the PI system without the proper permissions.

The DNP Master Driver in the OSIsoft PI Interface before 3.1.2.54 for DNP3 allows physically proximate attackers to cause a denial of service (interface shutdown) via crafted input over a serial line.

The DNP Master Driver in the OSIsoft PI Interface before 3.1.2.54 for DNP3 allows remote attackers to cause a denial of service (interface shutdown) via a crafted TCP packet.

AngularJS could allow a remote attacker to bypass security restrictions, caused by a prototype pollution flaw in the merge function. By sending a specially-crafted request using a constructor payload, a remote attacker could exploit this vulnerability to add or modify properties of Object.prototype.

A remote attacker with write access to PI ProcessBook files could inject code that is imported into OSIsoft PI Vision 2020 versions prior to 3.5.0. Unauthorized information disclosure, modification, or deletion is also possible if a victim views or interacts with the infected display. This vulnerability affects PI System data and other data accessible with victim’s user permissions.

OSIsoft PI Vision 2020 versions prior to 3.5.0 could disclose information to a user with insufficient privileges for an AF attribute.

Microsoft XML Core Services (aka MSXML) 3.0, 5.0, and 6.0 does not properly parse XML content, which allows remote attackers to execute arbitrary code via a crafted web page, aka "MSXML Integer Truncation Vulnerability."

PI Vision could disclose information to a user with insufficient privileges for an AF attribute that is the child of another attribute and is configured as a Limits property.

A remote authenticated attacker with write access to a PI Server could trick a user into interacting with a PI Web API endpoint and redirect them to a malicious website. As a result, a victim may disclose sensitive information to the attacker or be provided with false information.

A remote attacker with write access to PI Vision could inject code into a display. Unauthorized information disclosure, modification, or deletion is possible if a victim views or interacts with the infected display using Microsoft Internet Explorer. The impact affects PI System data and other data accessible with victim's user permissions.

The OSIsoft PI Interface for IEEE C37.118 before 1.0.6.158 allows remote attackers to cause a denial of service (memory consumption or memory corruption, instance shutdown, and data-collection outage) via crafted C37.118 configuration packets.

An authenticated remote attacker could use specially crafted URLs to send a victim using PI Vision 2019 mobile to a vulnerable web page due to a known issue in a third-party component.

The OSIsoft PI Interface for IEEE C37.118 before 1.0.6.158 allows remote attackers to cause a denial of service (instance shutdown and data-collection outage) via crafted C37.118 configuration packets that trigger an invalid read operation.

PI Coresight 2016 R2 contains a cross-site request forgery vulnerability that may allow access to the PI system. OSIsoft recommends that users upgrade to PI Vision 2017 or greater to mitigate this vulnerability.

An authenticated remote attacker could crash PI Archive Subsystem when the subsystem is working under memory pressure. This can result in blocking queries to PI Data Archive (2018 SP2 and prior versions).

OSIsoft PI System software (Applications using PI Asset Framework (AF) Client versions prior to PI AF Client 2016, Version 2.8.0; Applications using PI Software Development Kit (SDK) versions prior to PI SDK 2016, Version 1.4.6; PI Buffer Subsystem, versions prior to and including, Version 4.4; and PI Data Archive versions prior to PI Data Archive 2015, Version 3.4.395.64) operates between endpoints without a complete model of endpoint features potentially causing the product to perform actions based on this incomplete model, which could result in a denial of service. OSIsoft reports that in order to exploit the vulnerability an attacker would need to be locally connected to a server. A CVSS v3 base score of 7.1 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H)

PI Server in OSIsoft PI System before 3.4.380.x does not properly use encryption in the default authentication process, which allows remote attackers to read or modify information in databases via unspecified vectors.

Stack-based buffer overflow in OSIsoft PI OPC DA Interface before 2.3.20.9 allows remote authenticated users to execute arbitrary code by sending packet data during the processing of messages associated with OPC items.

OSIsoft PI AF 2.6 and 2.7 and PI SQL for AF 2.1.2.19 do not ensure that the PI SQL (AF) Trusted Users group lacks the Everyone account, which allows remote authenticated users to bypass intended command restrictions via SQL statements.

OSIsoft PI SQL Data Access Server (aka OLE DB) 2016 1.5 allows remote authenticated users to cause a denial of service (service outage and data loss) via a message.

OSIsoft PI AF Server before 2016 2.8.0 allows remote authenticated users to cause a denial of service (service outage) via a message.
