A high-severity denial-of-service (DoS) vulnerability, tracked as CVE-2025-9124, has been identified in Rockwell Automation's Compact GuardLogix 5370 programmable logic controllers (PLCs). The vulnerability arises when the device receives a specifically crafted CIP (Common Industrial Protocol) unconnected explicit message, which can trigger a major non-recoverable fault in the controller. This fault condition can render the affected PLC inoperable until it is manually reset or serviced, potentially disrupting industrial automation processes that rely on these controllers for safety and operational continuity. The vulnerability is remotely exploitable, meaning an attacker does not require physical access to the device to trigger the fault. Rockwell Automation has acknowledged the issue and published a security advisory (SD1755) to inform customers and provide guidance. The advisory confirms that the vulnerability has been corrected in updated product versions, though no workaround is available for unpatched systems. There is currently no evidence that this vulnerability has been exploited in the wild, and it is not listed as a Known Exploited Vulnerability (KEV) by Rockwell Automation. The company emphasizes the importance of applying the corrective updates to mitigate the risk. The vulnerability has been assigned a CVSS 4.0 base score of 8.7, indicating a high level of risk due to the potential for significant operational impact. The affected product line, Compact GuardLogix 5370, is widely used in industrial environments for safety-critical automation tasks. Details about the specific affected versions have not been disclosed in the public advisories, but customers are urged to consult Rockwell Automation's official channels for the most current information. The vulnerability was disclosed and remediated on October 14, 2025, with both the CVE and the vendor advisory published on the same day. Rockwell Automation's Product Security Incident Response Team (PSIRT) is credited as the source of the vulnerability report. Customers are advised to review their deployment of Compact GuardLogix 5370 controllers and apply the recommended updates as soon as possible to prevent potential service interruptions. The absence of a workaround underscores the urgency of patching, as operational continuity could be at risk if the vulnerability is exploited. Organizations should also review their network segmentation and access controls to limit exposure of industrial control systems to untrusted networks.

CISA released thirteen advisories detailing critical vulnerabilities affecting a range of industrial control system (ICS) products from major vendors including Rockwell Automation, Siemens, Hitachi Energy, Schneider Electric, and Delta Electronics. The advisories highlight severe security flaws such as missing authentication for critical functions, improper authorization, buffer overflows, SQL injection, and improper certificate validation. For Siemens TeleControl Server Basic, a vulnerability (CVE-2025-40765) allows unauthenticated remote attackers to obtain password hashes and perform authenticated operations on the database service, with a CVSS v3.1 score of 9.8, indicating critical risk. Rockwell Automation's FactoryTalk View Machine Edition and PanelView Plus 7 are susceptible to path traversal and improper authorization, potentially granting attackers unauthorized access to device file systems and sensitive diagnostic information. FactoryTalk ViewPoint is vulnerable to XML external entity injection, which could result in denial-of-service conditions. Siemens SiPass Integrated faces multiple issues, including buffer overflows and cross-site scripting, which could enable arbitrary code execution and unauthorized access. The Siemens SIMATIC ET 200SP Communication Processors have a missing authentication flaw that could allow attackers to access configuration data remotely. Siemens SINEC NMS is affected by a SQL injection vulnerability that could let low-privileged users escalate privileges. Siemens Solid Edge products are exposed to out-of-bounds read and write vulnerabilities, risking application crashes or code execution. Siemens HyperLynx and Industrial Edge App Publisher are vulnerable to type confusion, potentially leading to arbitrary code execution via crafted HTML pages. Hitachi Energy MACH GWS products have incorrect default permissions and improper validation issues, which could allow attackers to tamper with system files, cause denial of service, or perform man-in-the-middle attacks. The advisories provide technical details, affected product versions, and recommended mitigations, urging administrators to review and apply patches or workarounds. The vulnerabilities impact critical infrastructure sectors such as manufacturing, energy, water, and transportation, with products deployed worldwide. Many of the flaws are remotely exploitable with low attack complexity, increasing the urgency for remediation. CISA emphasizes the importance of timely action to prevent exploitation, as several vulnerabilities could lead to unauthorized access, data manipulation, or disruption of essential services. The advisories also reference the need to consult vendor-specific security updates for the most current information. Organizations are advised to assess their exposure, prioritize patching, and implement recommended security controls to mitigate these risks. The coordinated disclosure underscores the ongoing threat to ICS environments and the necessity for robust security practices across operational technology networks.

CISA republished multiple Rockwell Automation advisories covering vulnerabilities across **FactoryTalk Analytics PavilionX**, **RSLinx Classic**, **CompactLogix 5370**, **Logix 5370/5570 controllers**, and **FLEX I/O EtherNet/IP Adapters** used in critical manufacturing environments worldwide. The issues include an authorization bypass in PavilionX (`CVE-2025-14272`) that could let an unauthenticated attacker perform privileged administrative actions, and a third-party flaw in RSLinx Classic (`CVE-2020-13573`) tied to out-of-bounds read and stack-based buffer overflow conditions that could cause denial of service or enable remote arbitrary code execution. Additional advisories detail multiple **CIP-related denial-of-service weaknesses** in CompactLogix and Logix controllers, including `CVE-2026-11317`, where crafted CIP messages can trigger major nonrecoverable faults requiring a program download, as well as sequence-number, source-IP, and connection-ID issues that can induce controller faults. CISA also warned that FLEX I/O EtherNet/IP Adapters version `2.012` are affected by `CVE-2026-0646`, which can fault devices through malformed CIP requests, and `CVE-2026-0647`, a critical authentication bypass in the embedded web server that allows password changes through a crafted HTTP GET request, potentially leading to account takeover and loss of availability; CISA said no known public exploitation had been reported and urged operators to isolate control networks, reduce internet exposure, and secure remote access with firewalls and updated VPNs.
