September ICS Patch Tuesday brings critical fixes from Schneider Electric, Siemens, and Aveva, including CVSS 9.2 authentication flaw CVE-2026-3869 in Modicon M580 controllers.
Schneider Electric's September advisories include a critical authentication vulnerability, CVE-2026-3869 with a CVSS score of 9.2, in Modicon M580 and Modicon M580 Safety controllers, plus high-severity bugs in PowerLogic T300 and EcoStruxure IT Data Center Expert. Siemens published nine new advisories, four rated critical across Reyrolle 7SR5, Open Interface Services, Industrial Edge Management, and SIMOVE Fleetmanager and SIPLANT, and began rolling out fixes for CVE-2026-31431, a 7.8-rated Linux kernel flaw enabling root shell access. Aveva disclosed four flaws in Pipeline Integrity Monitor's PIMBoards, including a hardcoded encryption key and MD5-hashed passwords, plus an unsafe deserialization issue in Enterprise SCADA. Rockwell Automation separately issued nine advisories covering RSLinx Classic and multiple controller products.
Former Waco CIO argues cellular-connected water controllers sit outside scanned networks, and accountability plus operating-budget funding—not technology—block segmentation.
Writing as Waco, Texas's former CIO, the author describes July water-sector intrusions that CISA linked to over 100 compromised systems, typically controllers on public cellular links absent from asset lists. The FBI and EPA reported incidents at utilities in at least seven states since July 27, and a Clayton County, Georgia pump station failure triggered a boil-water advisory. He argues accountability and funding—using mechanisms like the Texas Water Development Board's new cybersecurity scoring criteria—are the binding constraints, citing Waco's 43-day segmentation of five treatment plants with operating funds.
CISA updated ICSA-26-169-07: CVE-2026-4827 (CVSS 8.3) insufficient entropy enables session hijacking across dozens of Schneider Electric grid products; fixes available.
CISA republished advisory ICSA-26-169-07 (Update A) for CVE-2026-4827, CWE-331 insufficient entropy in session management, scored CVSS 8.3. Affected lines include Easergy MiCOM relays and C5, EcoStruxure Power Automation (EPAS-GTW, EPAS-UI, iPMFLS), EcoStruxure Power Operation, PowerLogic P5/P7/T300/T500, and Saitel DP/T150 RTUs, with dozens of fixed versions listed. Successful exploitation could enable session hijacking and unauthorized operations on systems in energy, chemical, critical manufacturing, and water sectors. Fixes are available; no exploitation is reported.
Canada's Cyber Centre relayed Schneider Electric advisories for vulnerabilities in NetBotz 5-750/755 (5.5.2 and prior) and PowerChute Serial Shutdown (1.5 and prior).
The Canadian Centre for Cyber Security issued control-systems advisory AV26-871 noting Schneider Electric products affected by vulnerabilities as of September 1, 2026. Affected products include NetBotz 5-750/755 versions 5.5.2 and prior, and PowerChute Serial Shutdown versions 1.5 and prior, the latter with an improper restriction of excessive authentication attempts flaw. Administrators are urged to review Schneider Electric's security notifications and apply the suggested mitigations and updates.
Forescout used Anthropic's Claude to port a working pre-auth RCE exploit for CVE-2021-31886 between WAGO PLCs, executing ARM shellcode on live hardware.
Forescout Vedere Labs used Claude interactively to port an RCE exploit for CVE-2021-31886, a CVSS 9.8 stack buffer overflow in the Nucleus FTP server's USER command, from a WAGO 750-852 to a WAGO 750-831 PLC, running attacker-supplied ARM shellcode. The final RCE stage cost $535.74 in API usage over 8 hours 32 minutes, and a follow-up attempt to build a C2 implant permanently bricked the device. CERT@VDE lists many Nucleus V1-based WAGO models as vulnerable with no updates available; Siemens plans no Nucleus NET remediation. The work follows a joint NSA/CISA/FBI/DOE/EPA advisory warning of AI-generated exploitation scripts targeting internet-exposed Siemens S7 PLCs.
NSA, CISA, FBI, DOE, and EPA warn threat actors use AI-assisted scripts and snap7 libraries to access internet-exposed Siemens S7 PLCs in critical infrastructure sectors.
NSA, CISA, FBI, DOE, and EPA issued a joint advisory warning that threat actors combine open-source snap7.dll/python-snap7 libraries with AI-generated scripts to gain read/write access to Siemens S7-200 through S7-1500 PLCs over the S7comm protocol. Actors use Censys and ZoomEye to find internet-exposed devices and abuse default or weak credentials, with activity assessed as persistent reconnaissance and positioning for future write operations. Agencies urge device inventory, patching, removing PLCs from the internet, and hardening; the pattern resembles Iran-linked CyberAv3ngers targeting of Rockwell, Schneider, and Siemens PLCs.
NSA and FBI warn of an active campaign using AI-generated exploit scripts against Siemens S7 PLCs in critical infrastructure sectors.
NSA, FBI and other federal agencies issued an urgent advisory describing an active threat campaign targeting US-based Siemens S7 Series PLCs with AI-generated exploitation scripts disguised as legitimate monitoring tools. Actors use internet scanning to find exposed PLCs in energy, water, and manufacturing sectors, and may be preparing for operational effects. The advisory expands on July warnings of Iran-affiliated hackers targeting PLCs from Siemens, Schneider Electric, Rockwell Automation, and Allen-Bradley.
Local Privilege Escalation (Copy Fail) in Linux Kernel algif_aead Interface
CVE-2026-31431 ('Copy Fail') is an incorrect resource transfer between spheres (CWE-669/CWE-1288) in the Linux kernel's algif_aead implementation of the AF_ALG userspace crypto interface, introduced roughly nine years ago (around 2017, per public reporting) when commit 72548b093ee3 switched AEAD operations to in-place handling even though the source and destination buffers come from different mappings. A local, unprivileged user can trigger the flaw by performing AEAD operations through the AF_ALG socket interface, causing the kernel to mishandle the copy of ciphertext and associated data. Successful exploitation provides a reliable local privilege escalation to root (C:H/I:H/A:H per the CVSS vector). Nearly every major Linux distribution and enterprise platform is exposed, including the kernel itself, Red Hat Enterprise Linux (including AUS, EUS, TUS and Update Services for SAP Solutions), OpenShift Container Platform, Amazon Linux, Ubuntu, Debian, openSUSE Leap, SUSE CaaS Platform, NixOS, and Linux-based products from Arista and Siemens. The flaw has public proof-of-concept code, a 99.9% EPSS score, and was added to CISA's Known Exploited Vulnerabilities catalog on 2026-05-01, indicating exploitation in the wild (ransomware use is unknown).

Flawed Authentication Algorithm in Schneider Electric PLC Enables Full Compromise
CVE-2026-3869 is a critical (CVSS 4.0 score 9.2) incorrect implementation of an authentication algorithm (CWE-303) in a Schneider Electric programmable logic controller (PLC), disclosed and patched as part of Schneider Electric's ICS Patch Tuesday release. The flaw is reachable over the network with no privileges or user interaction required, but it carries elevated attack requirements: it comes into play when the PLC is running an application project with a lower application level, which is the configuration precondition for exploitation. An attacker who meets those conditions can defeat the controller's authentication mechanism and cause a complete loss of confidentiality, integrity and availability of the PLC (VC:H/VI:H/VA:H), meaning they could read, modify or disrupt the running control process. Affected users are operators of the impacted Schneider Electric PLC line; the available data does not name the specific model or firmware versions, so operators should confirm their exposure against the official Schneider notification. No public proof-of-concept is known and the flaw is not listed in CISA's KEV, with no reports of exploitation in the wild to date.
