Siemens and Schneider Electric have released their Patch Tuesday advisories for November 2022. Siemens has released nine new security advisories covering a total of 30 vulnerabilities, but Schneider has only published one new advisory.
Of Siemens’ nine advisories, three describe vulnerabilities that have been rated ‘critical’. Four vulnerabilities — one high-severity and three critical flaws — have been found in Sicam Q100 power meter devices. They can allow an attacker to hijack user sessions, crash the device, or execute arbitrary code.
Scalance W1750D devices have more than a dozen vulnerabilities — including many rated ‘critical’ — that could allow an attacker to execute arbitrary code or cause a denial-of-service (DoS) condition. Patches are not available, but the vendor has provided some mitigations. The company pointed out that the access point is a brand-labeled device made by Aruba Networks, which announced the availability of patches in late September.
The last Siemens advisory addressing a critical vulnerability describes a weak key protection issue in Sinumerik products. This issue was addressed last month in Simatic products, when the vendor said it could not rule out malicious exploitation in the future.

High-severity vulnerabilities have been patched in Teamcenter Visualization and JT2Go products (DoS and remote code execution), Parasolid (remote code execution), and QMS Automotive (credentials exposure).
Medium-severity flaws have been found in Ruggedcom ROS devices, industrial controllers, and the Sinec network management system.
In addition, between this and the previous Patch Tuesday, Siemens published an advisory describing a critical authentication bypass vulnerability affecting Siveillance Video mobile servers.
Schneider Electric has only published one new advisory. It covers three vulnerabilities that expose its NetBotz security and environmental monitors to cross-site scripting (XSS), account takeover, and clickjacking attacks. The French industrial giant has released patches.
