The US Cybersecurity and Infrastructure Security Agency (CISA) has urged vital infrastructure organizations to deal with vulnerabilities affecting 9 industrial management methods (ICS) merchandise.
The report, dated January 11, 2024, highlighted a collection of excessive and important severity vulnerabilities in merchandise broadly utilized in sectors like power, manufacturing and transportation.
Users and directors in these sectors are inspired to overview the advisories for technical particulars and mitigations.
Rapid Software LLC Rapid SCADA – CVSS 9.6 (Critical)
Impacting a Rapid Software product used within the power and transportation sectors are seven vulnerabilities that might end in risk actors concentrating on organizations in a wide range of methods.
These embrace studying delicate information from the Rapid Scada server, writing information to the Rapid Scada listing to attain code execution and getting access to delicate methods through legitimate-seeming phishing assaults.
CISA stated that Rapid Software didn’t reply to its makes an attempt at coordination. Users of Rapid SCADA are inspired to contact Rapid Software and hold their methods updated.
Horner Automation Cscape – CVSS 7.8 (High)
This stack-based buffer overflow vulnerability impacts the Cscape product variations 9.90 SP10 and prior, that are utilized by vital manufacturing companies.
There is a low assault complexity, and profitable exploitation can allow attackers to execute arbitrary code.
Customers are urged to use v9.90 SP11 or the most recent model of the Cscape software program to mitigate this vulnerability.
Schneider Electric Easergy Studio – CVSS 7.8 (High)
This deserialization of untrusted knowledge vulnerability impacts Easergy Studio variations previous to v9.3.5, an influence relay safety management software program utilized by power firms worldwide.
Successful exploitation can enable a risk actor to realize full management of a workstation.
It has a low assault complexity, and customers ought to apply v9.3.6, which comprises a repair for the vulnerability.

Siemens Teamcenter Visualization and JT2Go – CVSS 7.8 (High)
These 4 vulnerabilities have an effect on two Siemens merchandise used within the vital manufacturing trade.
They facilitate out-of-bounds studying, NULL pointer deference and stack-based buffer overflow exploits.
Customers are urged to replace JT2Go and Teamcenter Visualization merchandise to the most recent software program to mitigate these dangers. Users are additionally really helpful to keep away from opening untrusted CGM information within the two merchandise.
Siemens Spectrum Power 7 – CVSS 7.8 (High)
Affecting all Spectrum Power 7 variations previous to V23Q4, this incorrect permission task for vital useful resource vulnerability can enable an authenticated native attacker to inject arbitrary code and achieve root entry. There is a low assault complexity.
Critical manufacturing companies utilizing this product are really helpful to replace to V23Q4 or a later model to mitigate the chance posed.
Siemens SICAM A8000 – CVSS 6.6 (Medium)
This vulnerability can enable an authenticated distant attacker to inject instructions which can be executed on the gadget with root privileges throughout gadget startup.
It impacts the Siemens merchandise CP-8031 MASTER MODULE (6MF2803-1AA00) and CP-8050 MASTER MODULE (6MF2805-0AA00) variations previous to CPCI85 V05.20.
Siemens has knowledgeable vital manufacturing prospects of a number of workarounds and mitigations that may scale back the chance.
These mitigations embrace reviewing the customers who’ve permission to switch the community configuration and apply sturdy passwords and updating merchandise to CPCI85 V05.20 or later model.
Siemens SIMATIC CN 4100 – CVSS 9.8 (Critical)
These three vulnerabilities are exploitable remotely and have a low assault complexity.
Successful exploitation can enable an attacker to remotely login as root or trigger denial of service situation of the gadget.
SIMATIC CN 4100 prospects within the vital manufacturing trade ought to replace to V2.7 or later model.
Siemens SIMATIC – CVSS 10 (Critical)
Critical manufacturing companies utilizing SIMATIC IPC647E, SIMATIC IPC847E and SIMATIC IPC1047E ought to replace maxView Storage Manager to V4.14.00.26068 or later model to mitigate the chance.
Siemens Solid Edge – CVSS 7.8 (High)
All variations previous to V223.0 Update 10 are prone to heap-based buffer overflow, out of bounds write, stack-based buffer overflow and entry of uninitialized pointer whereas parsing specifically crafted PAR information by means of 11 vulnerabilities.
These vulnerabilities can allow an attacker to execute code within the context of the present course of, with a low assault complexity.
Siemens has urged vital manufacturing prospects to replace to V223.0 Update 10 or later model and keep away from opening untrusted information from unknown sources in Solid Edge.
Essential Cybersecurity Practices for ICS Systems
CISA additionally supplied the next recommendation to vital infrastructure organizations utilizing ICS:
- Keep methods up-to-date with new updates
- Minimize community publicity for all management system gadgets
- Isolate management system networks from enterprise networks
- Use safe strategies, resembling digital personal networks (VPNs) when distant entry is required
CISA added that it’s going to not be updating ICS safety advisories for Siemens product vulnerabilities as of January 10, 2024, past the preliminary advisory.
