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: 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: None: There is no loss of confidentiality within the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

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

Organizations should immediately inventory their network infrastructure to identify the presence of Weidmueller IE-SW-VL05M-5TX devices. Since no patches are currently available, mitigation should focus on network segmentation and access control to restrict exposure of these devices to untrusted networks, especially the internet. Implement strict firewall rules to block unauthorized access to the cmd services of these switches. Employ network intrusion detection systems (NIDS) to monitor for anomalous traffic patterns targeting these devices. Additionally, consider deploying virtual LANs (VLANs) and zero-trust network architectures to limit lateral movement in case of compromise. Regularly check vendor communications for patches or firmware updates addressing this vulnerability. Finally, develop and test incident response plans specific to ICS/OT environments to quickly respond to potential DoS incidents affecting critical network infrastructure.

Description

An unauthenticated remote attacker can exploit input validation in cmd services of the devices, allowing them to disrupt system operations and potentially cause a denial-of-service.

Impact

For European organizations, especially those in critical infrastructure sectors such as manufacturing, energy, transportation, and utilities, this vulnerability poses a significant risk. The Weidmueller IE-SW-VL05M-5TX is likely deployed in industrial control systems (ICS) and operational technology (OT) networks, where network switches are essential for reliable communication between controllers, sensors, and actuators. A successful DoS attack could disrupt production lines, cause operational downtime, and potentially lead to safety hazards if control systems lose connectivity. Given the increasing digitization and interconnectivity of industrial environments in Europe, this vulnerability could have cascading effects on supply chains and service availability. Furthermore, the unauthenticated nature of the exploit increases the threat surface, as attackers do not need credentials or insider access to launch an attack remotely.

CWE-1287Improper Validation of Specified Type of Input (opens in a new tab)
Base weakness
The product receives input that is expected to be of a certain type, but it does not validate or incorrectly validates that the input is actually of the expected type.
Implementation · Input Validation
Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
