Siemens SIMATIC and SICAM Products Vulnerable to Trace-File Code Injection and Other Flaws
CISA published an ICS advisory warning that multiple Siemens SIMATIC controllers do not properly sanitize the contents of imported trace files, enabling code injection if an attacker can socially engineer a legitimate user into importing a specially crafted trace file. The affected product set includes a broad range of SIMATIC devices, including SIMATIC Drive Controller CPU 1504D/1507D TF, multiple SIMATIC ET 200SP CPU variants (including fail-safe models), and SIMATIC S7-1500 CPUs, among others.
CERT-FR also issued an advisory covering multiple vulnerabilities in Siemens products, listing impacts that include remote code execution, denial of service, and indirect code injection (XSS), and enumerating overlapping affected systems such as the same SIMATIC Drive Controller and SIMATIC ET 200SP families. CERT-FR explicitly references CVE-2025-40943 for several of these SIMATIC devices and additionally notes other Siemens components (e.g., SICAM SIAPP SDK versions prior to 2.1.7), indicating the Siemens security updates/mitigations span more than one product line and vulnerability class beyond the trace-file injection issue highlighted by CISA.

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 ICS Advisories Highlight Multiple High-Impact Vulnerabilities Across Industrial and IoT Products
CISA published multiple Industrial Control Systems (ICS) advisories detailing vulnerabilities across a range of OT and connected-device products, including **critical** issues in *AVEVA Process Optimization* (multiple CVEs) that could enable unauthenticated **remote code execution**, SQL injection, privilege escalation, and sensitive data exposure in affected versions (<=2024.1). Additional advisories describe flaws in several **Siemens** product lines, including a DoS condition in **SIMATIC/SIPLUS ET 200** components triggered via an S7 protocol disconnect request (`CVE-2025-40944`), a TLS certificate upload input-validation issue that can crash/reboot **RUGGEDCOM ROS** devices (`CVE-2025-40935`), a local privilege escalation in **TeleControl Server Basic** prior to V3.1.2.4 (`CVE-2025-40942`), and multiple issues in **SINEC Security Monitor** (including improper authorization in `ssmctl-client` file transfer and report-generation DoS; `CVE-2025-40830`, `CVE-2025-40831`). CISA also noted vulnerabilities affecting **Siemens Industrial Edge** ecosystems, including an authorization bypass in the **Industrial Edge Device Kit** (`CVE-2025-40805`) and authentication enforcement weaknesses on specific API endpoints in **Industrial Edge Devices** that could allow impersonation if an attacker knows a legitimate user identity. Other CISA advisories covered **Schneider Electric EcoStruxure Power Build Rapsody** (`CVE-2025-13844`), where importing a malicious project file (SSD) could trigger memory corruption (e.g., double free/use-after-free) and potentially arbitrary code execution, and **Rockwell Automation FactoryTalk DataMosaix Private Cloud** (`CVE-2025-12807`), where low-privilege users could perform sensitive database operations via exposed API endpoints (SQL injection class). Separately, CISA warned about **YoSmart/YoLink** weaknesses (multiple CVEs) including insufficient authorization controls in the MQTT broker enabling cross-account device control when device IDs are obtained (with IDs described as predictable), plus additional issues such as cleartext transmission and predictable identifiers. A non-CISA item in the set reported Cisco releasing updates for a max-severity **AsyncOS** vulnerability under active exploitation (`CVE-2025-20393`) affecting *Secure Email Gateway* and *Secure Email and Web Manager* appliances, including evidence of attacker-installed persistence and attribution by Cisco Talos to **UAT-9686**; this is a separate enterprise email-security incident and not part of the ICS advisory set.
