Important Flaws in Tank Gauge Programs Expose Gasoline Stations to Distant Assaults

Important safety vulnerabilities have been disclosed in six completely different Computerized Tank Gauge (ATG) techniques from 5 producers that would expose them to distant assaults.

“These vulnerabilities pose vital real-world dangers, as they might be exploited by malicious actors to trigger widespread injury, together with bodily injury, environmental hazards, and financial losses,” Bitsight researcher Pedro Umbelino said in a report revealed final week.

Making issues worse, the evaluation discovered that 1000’s of ATGs are uncovered to the web, making them a profitable goal for malicious actors seeking to stage disruptive and harmful assaults in opposition to gasoline stations, hospitals, airports, navy bases, and different important infrastructure amenities.

ATGs are sensor techniques designed to observe the extent of a storage tank (e.g., gas tank) over a time frame with the purpose of figuring out leakage and parameters. Exploitation of safety flaws in such techniques may subsequently have severe penalties, together with denial-of-service (DoS) and bodily injury.

The newly found 11 vulnerabilities affect six ATG fashions, particularly Maglink LX, Maglink LX4, OPW SiteSentinel, Proteus OEL8000, Alisonic Sibylla, and Franklin TS-550. Eight of the 11 flaws are rated important in severity –

• CVE-2024-45066 (CVSS rating: 10.0) – OS command injection in Maglink LX
• CVE-2024-43693 (CVSS rating: 10.0) – OS command injection in Maglink LX
• CVE-2024-43423 (CVSS rating: 9.8) – Onerous-coded credentials in Maglink LX4
• CVE-2024-8310 (CVSS rating: 9.8) – Authentication bypass in OPW SiteSentinel
• CVE-2024-6981 (CVSS rating: 9.8) – Authentication bypass in Proteus OEL8000
• CVE-2024-43692 (CVSS rating: 9.8) – Authentication bypass in Maglink LX
• CVE-2024-8630 (CVSS rating: 9.4) – SQL injection in Alisonic Sibylla
• CVE-2023-41256 (CVSS rating: 9.1) – Authentication bypass in Maglink LX (a replica of a beforehand disclosed flaw)
• CVE-2024-41725 (CVSS rating: 8.8) – Cross-site scripting (XSS) in Maglink LX
• CVE-2024-45373 (CVSS rating: 8.8) – Privilege escalation in Maglink LX4
• CVE-2024-8497 (CVSS rating: 7.5) – Arbitrary file learn in Franklin TS-550

“All these vulnerabilities permit for full administrator privileges of the gadget software and, a few of them, full working system entry,” Umbelino mentioned. “Essentially the most damaging assault is making the units run in a method which may trigger bodily injury to their parts or parts related to it.”

Flaws Found in OpenPLC, Riello NetMan 204, and AJCloud

Safety flaws have additionally been uncovered within the open-source OpenPLC resolution, together with a important stack-based buffer overflow bug (CVE-2024-34026, CVSS rating: 9.0) that might be exploited to realize distant code execution.

“By sending an ENIP request with an unsupported command code, a legitimate encapsulation header, and not less than 500 complete bytes, it’s potential to jot down previous the boundary of the allotted log_msg buffer and corrupt the stack,” Cisco Talos said. “Relying on the safety precautions enabled on the host in query, additional exploitation might be potential.”

One other set of safety holes concern the Riello NetMan 204 community communications card utilized in its Uninterruptible Energy Provide (UPS) techniques that would allow malicious actors to take over management of the usand even tamper with the collected log knowledge.

• CVE-2024-8877 – SQL injection in three API endpoints /cgi-bin/db_datalog_w.cgi, /cgi-bin/db_eventlog_w.cgi, and /cgi-bin/db_multimetr_w.cgi that enables for arbitrary knowledge modification
• CVE-2024-8878 – Unauthenticated password reset through the endpoint /recoverpassword.html that might be abused to acquire the netmanid from the gadget, from which the restoration code for resetting the password could be calculated

“Inputting the restoration code in ‘/recoverpassword.html’ resets the login credentials to admin:admin,” CyberDanube’s Thomas Weber said, noting that this might grant the attacker the power to hijack the gadget and switch it off.

Each vulnerabilities stay unpatched, necessitating that customers restrict entry to the units in important environments till a repair is made accessible.

Additionally of word are a number of important vulnerabilities within the AJCloud IP digicam administration platform that, if efficiently exploited, may result in the publicity of delicate person knowledge and supply attackers with full distant management of any digicam related to the sensible house cloud service.

“A built-in P2P command, which deliberately supplies arbitrary write entry to a key configuration file, could be leveraged to both completely disable cameras or facilitate distant code execution by way of triggering a buffer overflow,” Elastic Safety Labs said, stating its efforts to succeed in the Chinese language firm have been unsuccessful to this point.

CISA Warns of Continued Assaults In opposition to OT Networks

The event comes because the U.S. Cybersecurity and Infrastructure Safety Company (CISA) flagged elevated threats to internet-accessible operational know-how (OT) and industrial management techniques (ICS) units, together with these within the Water and Wastewater Programs (WWS) Sector.

“Uncovered and weak OT/ICS techniques could permit cyber menace actors to make use of default credentials, conduct brute power assaults, or use different unsophisticated strategies to entry these units and trigger hurt,” CISA said.

Earlier this February, the U.S. authorities sanctioned six officers related to the Iranian intelligence company for attacking important infrastructure entities within the U.S. and different nations.

These assaults involved concentrating on and compromising Israeli-made Unitronics Imaginative and prescient Collection programmable logic controllers (PLCs) which might be publicly uncovered to the web by way of the usage of default passwords.

Industrial cybersecurity firm Claroty has since open-sourced two instruments known as PCOM2TCP and PCOMClient that permit customers to extract forensics data from Unitronics-integrated HMIs/PLCs.

“PCOM2TCP, allows customers to transform serial PCOM messages into TCP PCOM messages and vice versa,” it said. “The second device, known as PCOMClient, allows customers to connect with their Unitronics Imaginative and prescient/Samba sequence PLC, question it, and extract forensic data from the PLC.”

Moreover, Claroty has warned that the extreme deployment of distant entry options inside OT environments – wherever between 4 and 16 – creates new safety and operational dangers for organizations.

“55% of organizations deployed 4 or extra distant entry instruments that join OT to the skin world, a worrisome share of corporations which have expansive assault surfaces which might be advanced and costly to handle,” it noted.

“Engineers and asset managers ought to actively pursue to remove or decrease the usage of low-security distant entry instruments within the OT surroundings, particularly these with identified vulnerabilities or these missing important security measures reminiscent of MFA.”
