Rewterz Threat Advisory – ICS: OSIsoft PI System Multiple Vulnerabilities

May 13, 2020

Severity

Medium

Analysis Summary

CVE-2020-10610

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.

CVE-2020-10608

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.

CVE-2020-10606

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.

CVE-2020-10604

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.

CVE-2020-10602 

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.

CVE-2020-10600

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.

CVE-2019-10768

An authenticated remote attacker could add or modify internal object properties, resulting in undefined behavior.

CVE-2020-10614 

An authenticated remote attacker with write access to PI Vision databases could inject code into a display. Unauthorized information disclosure, deletion, or modification is possible if a victim views the infected display.

CVE-2019-18244

A local attacker could view sensitive information in log files when service accounts are customized during installation or upgrade of PI Vision. The update fixes a previously reported issue.

Impact

  • Cross site scripting 
  • Insertion of Sensitive Information into Log File
  • Uncontrolled Search Path Element
  • Incorrect Default Permissions
