Attack Vector: Network
Attack Complexity: Low

User Interaction: Required
Scope: Unchanged
Confidentiality: None
Integrity: Low
Availability: None

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: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
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: None: There is no loss of confidentiality within 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: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 15 Jan 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

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

Implement frame-busting HTTP headers on the TDC-X401GL web interface, such as X-Frame-Options set to DENY or SAMEORIGIN, or Content-Security-Policy with frame-ancestors directive to restrict framing.
If firmware updates become available from SICK AG, apply them promptly to address this vulnerability.
Segment the network to isolate the TDC-X401GL devices from general user networks, limiting exposure to potentially malicious webpages.
Educate users and operators about the risks of clicking unknown or suspicious links, especially those that could embed device interfaces.
Employ web gateway or proxy solutions that can detect and block malicious framing attempts or suspicious web content.
Monitor device logs and network traffic for unusual access patterns that might indicate attempted exploitation.
Consider deploying browser security extensions or policies that prevent framing from untrusted sources in environments where device interfaces are accessed.
Review and harden device access controls to minimize potential impact if clickjacking is successful.

Description

An attacker may exploit missing protection against clickjacking by tricking users into performing unintended actions through maliciously crafted web pages, leading to the extraction of sensitive data.

Impact

For European organizations, especially those in manufacturing, industrial automation, and critical infrastructure sectors using the SICK AG TDC-X401GL, this vulnerability could lead to unauthorized manipulation of device settings or extraction of sensitive operational data. Such unauthorized actions could disrupt automated processes, degrade system reliability, or expose sensitive operational parameters. Although the vulnerability does not directly compromise confidentiality, the integrity of device configurations is at risk, potentially causing operational inefficiencies or safety hazards. The requirement for user interaction means social engineering or phishing campaigns could be used to exploit this vulnerability, increasing risk in environments where employees access device interfaces via web browsers. The absence of known exploits reduces immediate risk, but the public disclosure means attackers could develop exploits. Given the critical role of these devices in industrial environments, even medium-severity vulnerabilities warrant prompt attention to avoid cascading effects on production lines or safety systems.

CWE-1021Improper Restriction of Rendered UI Layers or Frames (opens in a new tab)
Base weaknessOWASP Top 10 A06:2025: Insecure Design (opens in a new tab)
The web application does not restrict or incorrectly restricts frame objects or UI layers that belong to another application or domain.
Implementation
The use of X-Frame-Options allows developers of web content to restrict the usage of their application within the form of overlays, frames, or iFrames. The developer can indicate from which domains can frame the content.
Implementation
A developer can use a "frame-breaker" script in each page that should not be framed. This is very helpful for legacy browsers that do not support X-Frame-Options security feature previously mentioned.
Implementation
This defense-in-depth technique can be used to prevent the improper usage of frames in web applications. It prioritizes the valid sources of data to be loaded into the application through the usage of declarative policies.
