1 Advisory Published – 3-26-20


Today the CISA NCCIC-ICS published one control system security advisory for products from Advantech.

Advantech Advisory

This advisory describes a stack-based buffer overflow in the Advantech WebAccess HMI platform. The vulnerability was reported by Peter Cheng of Elex CyberSecurity. Advantech has a new version that mitigates the vulnerability. There is no indication that Cheng was provided an opportunity to verify the efficacy of the fix.

NCCIC-ICS reports that a relatively low-skilled attacker could remotely exploit the vulnerability to allow remote code execution.

NOTE: I wonder if this could be the same vulnerability that was reported by Tenable back in December. Different CVE numbers, but that does not mean a lot. Not enough detail in the NCCIC-ICS report to really tell.

S 79 Reported in Senate – Energy Sector Security


This week the Senate Energy and Natural Resources Committee published their report on S 79, the Securing Energy Infrastructure Act. It was accompanied by the revised language for the bill that was adopted by that Committee earlier this year. The next step for the bill will be for its consideration before the Senate.

I have already covered the changes in the bill so most of this report is old news. The ‘Background and Need’ section of the report (pgs 3-4) is well worth reading as a succinct statement about the state of control system security, at least as it is seen by Congress. The whole thing is worth reading, but I would like to quote the last paragraph in full:

“As it has become increasingly clear that industrial control systems are vulnerable to attack, it has also become apparent that there is insufficient information available to the Department of Energy, the National Laboratories, electric utilities, manufacturers of grid-related equipment, and other interested entities about the security vulnerabilities of these systems. Also lacking is a sufficient evaluation of technology and standards to isolate and defend industrial control systems from security vulnerabilities in the most critical systems. Finally, as identifying cyber vulnerabilities and defending against them is a responsibility shared by multiple government agencies and private sector institutions including asset owners, further opportunities for working-level collaboration by these entities are necessary.”

It will be interesting to see if/when this bill makes it to the floor of the Senate. With the strong bipartisan support that it received in Committee, I expect that it will be able to pass if it is considered. Again, probably the strongest impediment to this bill passing is the $11.5 million authorized to supports its requirements. That is federal-chump-change, but the money has to come from somewhere and that can be contentious.
