Oil and gasoline circulation computer systems and distant controllers made by Swiss industrial know-how agency ABB are affected by a severe vulnerability that might enable hackers to trigger disruptions and forestall utilities from billing their prospects, based on industrial cybersecurity agency Claroty.

Utilities depend on circulation computer systems to calculate oil and gasoline circulation charges and quantity. These gadgets, which are sometimes used within the electrical energy sector, play an vital position in course of security, in addition to billing.

Researchers at Claroty confirmed how an attacker with entry to a focused circulation laptop can bypass authentication utilizing a brute-force assault, after which exploit a path traversal vulnerability to learn the machine’s shadow password file to acquire its root account password. The identical vulnerability can be utilized to change the SSH configuration file to allow password authentication and permit the attacker to entry the machine with root privileges.

This complete exploit chain can enable a distant, unauthenticated attacker to execute arbitrary code with root privileges. The hacker can take full management of the machine and disrupt its skill to measure oil and gasoline circulation, which might forestall the sufferer from billing prospects.

One good instance of the significance of billing techniques is offered by the 2021 Colonial Pipeline ransomware assault, the place the corporate reportedly halted operations not as a result of the hackers hit operational know-how (OT) techniques, however as a result of its billing system was compromised.

Claroty reported its findings to ABB, which introduced the discharge of firmware patches for affected merchandise in July. The trail traversal vulnerability is tracked as CVE-2022-0902 and it has been assigned a ‘excessive severity’ ranking.

ABB has decided that its XFC G5 and uFLO G5 circulation computer systems, RMC-100, XRC G5, and XIO distant controllers, in addition to the Totalflow Common Knowledge Controller (UDC) are impacted. The seller stated in its July advisory that it was not conscious of any assaults exploiting the vulnerability.

Claroty has printed a weblog submit detailing its analysis, in addition to a video displaying how an attacker might hack a tool.
