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."

In OSIsoft PI Web API 2019 Patch 1 (1.12.0.6346) and all previous versions, the affected product is vulnerable to a cross-site scripting attack, which may allow an attacker to remotely execute arbitrary code.

In OSIsoft PI Web API and prior, the affected product is vulnerable to a direct attack due to a cross-site request forgery protection setting that has not taken effect.

OSIsoft PI Vision, All versions of PI Vision prior to 2019. The affected product is vulnerable to a cross-site request forgery that may be introduced on the PI Vision administration site.

A Cross-Site Request Forgery issue was discovered in OSIsoft PI Web API versions prior to 2017 (1.9.0). The vulnerability allows cross-site request forgery (CSRF) attacks to occur when an otherwise-unauthorized cross-site request is sent from a browser the server has previously authenticated.

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.

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.

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.

In OSIsoft PI System multiple products and versions, a local attacker can exploit incorrect permissions set by affected PI System software. This exploitation can result in unauthorized information disclosure, deletion, or modification if the local computer also processes PI System data from other users, such as from a shared workstation or terminal server deployment.

In OSIsoft PI System multiple products and versions, a local attacker can modify a search path and plant a binary to exploit the affected PI System software to take control of the local computer at Windows system privilege level, resulting in unauthorized information disclosure, deletion, or modification.

In OSIsoft PI System multiple products and versions, a local attacker can plant a binary and bypass a code integrity check for loading PI System libraries. This exploitation can target another local user of PI System software on the computer to escalate privilege and result in unauthorized information disclosure, deletion, or modification.

A Deserialization of Untrusted Data issue was discovered in OSIsoft PI Data Archive versions 2017 and prior. Unauthenticated users may modify deserialized data to send custom requests that crash the server.

An Incorrect Default Permissions issue was discovered in OSIsoft PI Data Archive versions 2017 and prior. Insecure default configuration may allow escalation of privileges that gives the actor full control over the system.

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.

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.

In OSIsoft PI System multiple products and versions, a remote, unauthenticated attacker could crash PI Network Manager service through specially crafted requests. This can result in blocking connections and queries to PI Data Archive.

An Improper Authentication issue was discovered in OSIsoft PI Server 2017 PI Data Archive versions prior to 2017. PI Data Archive has protocol flaws with the potential to expose change records in the clear and allow a malicious party to spoof a server within a collective.

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.

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).

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.

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.

In OSIsoft PI System multiple products and versions, an authenticated remote attacker could crash PI Network Manager due to a race condition. This can result in blocking connections and queries to PI Data Archive.

OSIsoft PI Web API 2018 and prior may allow disclosure of sensitive information.

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.

OSIsoft PI Vision, All versions of PI Vision prior to 2019. The affected product is vulnerable to an improper access control, which may return unauthorized tag data when viewing analysis data reference attributes.

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.

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.
