Security scientists have identified six critical vulnerabilities in third-party code which could expose plenty of operational technology (OT) environments to remote code execution assaults.
A team at Claroty located the bugs in Wibu-Systems’ CodeMeter software program license administration giving, commonly applied by several major sellers of industrial manage process (ICS) merchandise.
They have been specified a collective CVSS score by the ICS-CERT of 10., representing the highest stage of criticality.
“Successful exploitation of these vulnerabilities could let an attacker to alter and forge a license file, lead to a denial-of-assistance problem, probably achieve distant code execution, read heap data and reduce normal operation of third-celebration software package dependent on the CodeMeter,” the US Cybersecurity and Infrastructure Security Company (CISA) famous.
Attackers could phish their targets, socially engineering them into viewing a malicious website underneath their handle to inject a malicious license on to the target machine. Or they could exploit a single of the bugs to produce and inject solid licenses on to a equipment jogging CodeMeter, Claroty reported.
The business claimed the worst of the bugs allow for attackers to compromise the CodeMeter communication protocol and internal API, allowing for them to ship commands to any machine managing the code.
This could empower comprehensive distant takeover, making it possible for attackers to install ransomware or other exploits and/or crash programmable logic controllers (PLCs) since of the malicious license.
Mitigating the danger is built extra challenging by advantage of the reality that quite a few OT supervisors might not know a susceptible variation of CodeMeter is functioning. Claroty recommended scanning for the merchandise, blocking TCP port 22350 and contacting ICS vendors to check if they can manually upgrade the third-get together part of CodeMeter.
A report from Claroty past month claimed that above 70% of ICS vulnerabilities disclosed in the very first 50 % of the calendar year can be remotely exploited.
