On October 8, 2024, Siemens published 13 advisories, Schneider Electric published eight, and Phoenix Contact published one; CERT@VDE also disclosed a vulnerability affecting multiple Pepperl+Fuchs products. The issues ranged from code execution and administrative access to denial of service and information disclosure. This is a record of that disclosure cycle, not a current list of affected products or patch status: check the latest vendor advisory and revision before taking action.
What the October 2024 ICS Patch Tuesday covered
SecurityWeek’s October 9, 2024 roundup counted 13 Siemens advisories, eight Schneider Electric advisories, and one Phoenix Contact advisory. Those totals describe the number of advisories reported, not comparative product security. A larger count does not establish that one vendor’s products are more vulnerable than another’s.
Across the reported issues, impacts included arbitrary code execution, administrative access, denial of service, information disclosure, privilege escalation, and escape from kiosk mode. Practical risk depends on the particular product and version, how it is exposed, the conditions needed for exploitation, and the vendor’s available fix or mitigation.

What Siemens reported
Siemens issued 13 advisories in the October 8 disclosure cycle. The roundup identified critical-severity issues involving Sinec Security Monitor, SENTRON PAC3200, WibuKey dongles, HiMed Cockpit, and SENTRON Powercenter 1000. It also reported high-severity arbitrary code execution issues in Teamcenter Visualization, JT2Go, Simcenter Nastran, and Tecnomatix Plant Simulation, and medium-severity issues affecting Ruggedcom APE1808LNX, Questa and ModelSim, and SIMATIC S7-1500 and S7-1200 products.

SENTRON PAC3200: administrative access over Modbus TCP
Siemens ProductCERT advisory SSA-850560 describes CVE-2024-41798, involving the PAC3200’s four-digit PIN for administrative access. A party able to access the Modbus TCP interface could brute-force the PIN or observe cleartext communications. Siemens assigned the vulnerability CVSS 3.1 score 9.8 and CVSS 4.0 score 9.3. The advisory said no fix was planned at that time and advised treating the PIN as protection against inadvertent operation, not malicious access.
Siemens contrasted the PAC3200 with the successor SENTRON PAC3220, which it says adds a hardware switch to disable remote administrative write access and brute-force protection. That product comparison does not change the PAC3200 advisory’s status: consult Siemens’ current record for any later update or customer action.
WibuKey Runtime: update the Windows client component
For advisory SSA-368868, dated October 8, 2024, Siemens recommended WibuKey Runtime for Windows version 6.70 or later on affected Windows clients using WibuKey dongles. This remediation concerns the Windows runtime component; it should not be read as a blanket instruction to replace or update a controller. Confirm applicability against the Siemens advisory for the specific setup.

The October roundup reported issues in products used for industrial security monitoring, visualization, engineering, simulation, medical cockpit, and power monitoring. The summary does not provide affected versions or detailed mitigations for every item. For an operational decision, identify the exact product and version, then use its Siemens ProductCERT record rather than inferring exposure from the product-family name or severity label.

Which Schneider Electric products were affected?
SecurityWeek’s roundup summarized eight Schneider Electric advisories. The reported affected products and issues were:
- Harmony and Pro-face PS5000 legacy industrial PCs: critical information disclosure.
- Harmony iPC HMIBSC IIoT Edge Box Core: critical and high-severity Yocto OS vulnerabilities; the operating system was described as not updatable because of hardware limitations.
- EcoStruxure EV Charging Expert: vulnerabilities in the same Yocto OS.
- Easergy Studio: high-severity privilege escalation.
- Data Center Expert: high-severity information disclosure.
- EcoStruxure Power Monitoring Expert: high-severity remote code execution.
- EVlink Home Smart and Schneider Charge stations: high-severity information disclosure.
- Zelio Soft 2: remote code execution and denial of service.
This roundup-level summary does not establish affected versions, exposure conditions, or precise remediation for each product. Schneider Electric’s current security notifications are the authoritative place to verify those details and check for revisions. In particular, where an operating-system update is constrained by hardware, follow the vendor’s product-specific guidance rather than assuming a generic OS update is available.
Phoenix Contact PLCnext Engineer advisory
SecurityWeek reported one Phoenix Contact advisory covering several high-severity denial-of-service vulnerabilities in PLCnext Engineer involving third-party components. Phoenix Contact’s PSIRT archive identifies the item as VDE-2024-067, dated October 2, 2024, and notes that its advisories are published with VDE CERT. The available summary does not establish a specific fixed version or mitigation; check the current VDE-2024-067 record and its revision for the applicable remedy.
CERT@VDE advisory on Pepperl+Fuchs and regreSSHion
The roundup also covered a CERT@VDE advisory about OpenSSH’s regreSSHion vulnerability in multiple Pepperl+Fuchs products. CERT@VDE’s statement, reproduced by SecurityWeek, said the devices ran an affected SSH server even though users could not log in through SSH, and that attackers might exploit the issue to gain root access. The fact that interactive SSH login is unavailable therefore should not, by itself, be treated as proof that the vulnerability is inapplicable. The roundup does not supply affected versions or a detailed mitigation; consult the coordinated advisory before acting.

How to use this historical roundup safely
Do not use the October 2024 list as a current affected-product inventory. Advisories can be revised, and later notices may add products, versions, or remediation details. For each installation, verify the record against the exact product and version and review the latest vendor instructions.
- Identify the asset precisely. Record the product name, model, software or firmware version, operating system, and relevant network interfaces.
- Find the vendor’s original advisory. Use Siemens ProductCERT for Siemens products, Schneider Electric’s security notifications for Schneider products, and Phoenix Contact’s PSIRT archive or the coordinated VDE CERT publication for Phoenix Contact matters.
- Check the conditions and consequences. Determine whether the issue requires network or physical access, which interface is involved, and whether the impact is confidentiality, integrity, availability, or elevated privilege.
- Apply only the remediation that matches the record. Confirm fixed versions, workarounds, or an explicit absence of a fix in the current advisory. If a fix is unavailable, use the vendor’s stated mitigations and assess exposure with the responsible operational technology team.
- Recheck the advisory revision. Use the vendor portal’s latest version before making or documenting a remediation decision.
Where to check current ICS advisories
Siemens ProductCERT describes its advisories as validated vulnerabilities involving Siemens products that require an update, upgrade, or other customer action; its portal offers mailing-list, RSS, and CSAF updates. Phoenix Contact’s PSIRT archive is updated with advisory information and points readers to CERT@VDE for coordinated publication. Schneider Electric maintains a live security-notifications page.
Current government bulletins can provide another monitoring channel, but they are summaries rather than substitutes for the vendor’s product-specific instructions. CISA bulletins dated September 15, 17, and 22, 2026 included advisories concerning products from Siemens and Schneider Electric, among other notices. Their presence illustrates that vendor-specific ICS advisories continue to appear; it does not mean every listed product shares the same vulnerability or severity. Verify each item in its original vendor record.
