Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Monitor Advantech’s official channels for patches or security advisories addressing CVE-2025-46268 and apply updates promptly once available.
Restrict network access to the WebAccess/SCADA interface using firewalls, VPNs, or network segmentation to limit exposure to trusted users and systems only.
Implement strict input validation and sanitization on all user inputs interacting with the SCADA system to prevent injection attacks.
Employ application-layer firewalls or intrusion detection/prevention systems (IDS/IPS) configured to detect and block SQL injection patterns targeting SCADA components.
Conduct regular security assessments and penetration testing focused on SCADA environments to identify and remediate injection and other vulnerabilities.
Enforce the principle of least privilege for user accounts accessing the SCADA system to minimize the impact of compromised credentials.
Maintain detailed logging and monitoring of SCADA system activities to detect anomalous behavior indicative of exploitation attempts.
Develop and test incident response plans specific to industrial control system compromises to ensure rapid containment and recovery.
Educate operational technology (OT) personnel about the risks of injection vulnerabilities and secure configuration practices.
Where possible, isolate SCADA networks from corporate IT networks to reduce attack surface and lateral movement opportunities.

Description

CVE-2025-46268 is a medium-severity SQL injection vulnerability in Advantech WebAccess/SCADA version 9.2.1. It allows an attacker with low privileges to execute arbitrary SQL commands remotely without user interaction. This flaw can impact confidentiality, integrity, and availability of the affected SCADA system. Although no known exploits are reported in the wild yet, the vulnerability poses a significant risk to industrial control environments. European organizations using this SCADA platform should prioritize patching or mitigating this issue. The vulnerability is particularly relevant to countries with critical infrastructure relying on Advantech SCADA solutions. Mitigation requires applying vendor patches once available, restricting access to the SCADA interface, and implementing strict input validation and network segmentation. Given the critical role of SCADA systems in industrial and utility sectors, exploitation could lead to operational disruptions and data compromise.

Impact

For European organizations, the impact of CVE-2025-46268 can be significant, especially those operating critical infrastructure such as energy grids, water treatment plants, manufacturing, and transportation systems that rely on Advantech WebAccess/SCADA. Exploitation could lead to unauthorized access to sensitive operational data, manipulation of control commands, and disruption of industrial processes, potentially causing physical damage or service outages. The confidentiality breach could expose proprietary or operational data, while integrity violations might result in incorrect system behavior or unsafe conditions. Availability impacts could cause downtime, affecting service delivery and safety. Given the interconnected nature of European critical infrastructure and regulatory requirements for cybersecurity (e.g., NIS Directive), such vulnerabilities pose compliance risks and could attract regulatory scrutiny. The medium severity rating suggests that while the vulnerability is not trivially exploitable by unauthenticated attackers, it still requires prompt attention to prevent escalation and lateral movement within networks. The absence of known exploits in the wild provides a window for proactive defense but should not lead to complacency. The threat is particularly relevant for sectors with high reliance on SCADA systems and where Advantech products have market presence.

CWE-89Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') (opens in a new tab)
Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #2OWASP Top 10 A05:2025: Injection (opens in a new tab)
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Architecture and Design · Parameterization
If available, use structured mechanisms that automatically enforce the separation between data and code. These mechanisms may be able to provide the relevant quoting, encoding, and validation automatically, instead of relying on the developer to provide this capability at every point where output is generated.
Architecture and Design · Operation · Environment Hardening
Run your code using the lowest privileges that are required to accomplish the necessary tasks. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment.
