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.

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 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.

OSIsoft PI Web API

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.

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

A Cross-site Scripting issue was discovered in OSIsoft PI Web API versions 2017 R2 and prior. Cross-site scripting may occur when input is incorrectly neutralized.

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.
