Successful exploitation of this vulnerability could allow an attacker to gain unauthorized access to any Power BI reports installed or manipulate asset issue comments on assets.
Hitachi Energy reports the following products are affected:
3.2.1 IMPROPER ACCESS CONTROL CWE-284
Hitachi Energy Lumada APM has a flaw in the access control mechanism implementation on the “Limited Engineer” role, granting access to the embedded Power BI reports feature. This could allow an unauthorized user to access information by gaining unauthorized access to any installed Power BI reports, then manipulating asset issue comments on assets that should not be available to that user.
CVE-2022-2155 has been assigned to this vulnerability. A CVSS v3 base score of 5.7 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:N/A:N).
Hitachi Energy reported this vulnerability to CISA.
Hitachi Energy advises users that the vulnerability is remediated in Lumada APM v6.4.0.1. Lumada APM v6.5.0.0 and later are not affected.
According to Hitachi Energy, the “On Premise” edition of Lumada APM does not support the Power BI integration feature. However, users can connect a subscription-based Power BI to Lumada APM.
If the Power BI integration feature is enabled, Hitachi Energy recommends:
Note: If Power BI integration is disabled, it is safe to continue to assign the “Limited Engineer” role to users.
Hitachi Energy also recommends the following security practices:
Hitachi Energy advises that process control systems should not be used for internet surfing, instant messaging, or receiving emails. Portable computers and removable storage media should be carefully scanned for viruses before connecting to a control system.
