The U.S. Cybersecurity and Infrastructure Security Company (CISA) has revealed 4 Industrial Handle Systems (ICS) advisories, calling out several security flaws influencing products from Siemens, GE Digital, and Contec.
The most critical of the issues have been identified in Siemens SINEC INS that could guide to distant code execution by means of a route traversal flaw (CVE-2022-45092, CVSS score: 9.9) and command injection (CVE-2022-2068, CVSS rating: 9.8).
Also patched by Siemens is an authentication bypass vulnerability in llhttp parser (CVE-2022-35256, CVSS score: 9.8) as well as an out-of-bounds create bug in the OpenSSL library (CVE-2022-2274, CVSS score: 9.8) that could be exploited to trigger distant code execution.

The German automation organization, in December 2022, produced Services Pack 2 Update 1 software program to mitigate the flaws.
Individually, a critical flaw has also been discovered in GE Digital’s Proficy Historian resolution that could consequence in code execution no matter of authentication position. The issue, tracked as CVE-2022-46732 (CVSS rating: 9.8), impacts Proficy Historian variations 7. and greater, and has been remediated in Proficy Historian 2023.
“An attacker can consider gain of this actuality and bypass the historian authentication by impersonating a regional service,” Uri Katz, security researcher at industrial security firm Claroty, said. “This allows remote attackers the means to log in to any GE Proficy Historian server and drive it to accomplish unauthorized actions.”
CISA also up to date an ICS advisory that was printed very last thirty day period, detailing a critical command injection vulnerability in Contec CONPROSYS HMI Program (CVE-2022-44456, CVSS rating: 10.) that could allow a distant attacker to ship specially crafted requests to execute arbitrary commands.
Even though this shortcoming was patched by Contec in edition 3.4.5, the software program has given that been observed to be susceptible to four additional defects that could guide to facts disclosure and unauthorized entry.
People of CONPROSYS HMI Program are advisable to update to version 3.5. or afterwards, in addition to getting ways to decrease network exposure and isolate this sort of gadgets from enterprise networks.
The advisories come much less than a 7 days just after CISA unveiled 12 these alerts warning of critical flaws impacting software from Sewio, InHand Networks, Sauter Controls, and Siemens.
