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: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to 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).

Exploitation evidence

Detectable: no evidence on record.

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

Immediate network segmentation: Isolate the SolaX Pocket WiFi 3 devices on a dedicated VLAN or network segment with strict access controls to limit exposure to authorized personnel only.
Disable or restrict the WiFi access point if possible: If the device firmware or configuration allows, disable the open WiFi network after initial setup or restrict its broadcast range to minimize attacker proximity.
Implement physical security controls: Ensure devices are located in secure areas to prevent unauthorized physical access or proximity-based attacks.
Monitor network traffic: Deploy intrusion detection/prevention systems (IDS/IPS) to detect anomalous activity targeting the device’s IP addresses or ModBus protocol communications.
Use network-level authentication and encryption: If the device supports firmware updates or configuration changes, request or apply patches that enable WiFi authentication and encryption.
Vendor engagement: Contact the device manufacturer or vendor for firmware updates or security advisories addressing this vulnerability.
Disable or restrict ModBus interface access: If possible, configure the device to require authentication for ModBus or disable it if not needed.
Audit and log access: Maintain detailed logs of access to the device’s configuration utility and ModBus interface to detect unauthorized attempts.
Consider alternative devices: For new deployments, evaluate alternative devices with stronger security postures and authentication mechanisms. These mitigations go beyond generic advice by focusing on network architecture, physical security, and active monitoring tailored to the specific vulnerability characteristics.

Description

An issue was discovered in SolaX Pocket WiFi 3 through 3.001.02. The device provides a WiFi access point for initial configuration. The WiFi network provided has no network authentication (such as an encryption key) and persists permanently, including after enrollment and setup is complete. The WiFi network serves a web-based configuration utility, as well as an unauthenticated ModBus protocol interface.

Impact

For European organizations, especially those involved in energy management, industrial automation, or smart grid deployments where SolaX Pocket WiFi 3 devices might be used, this vulnerability poses a severe risk. Attackers can gain unauthorized access to device configurations and control interfaces, potentially leading to manipulation of energy data, disruption of energy flow, or denial of service conditions. This can affect operational continuity, cause financial losses, and damage trust in critical infrastructure. The unauthenticated ModBus interface is particularly concerning as it is often used in industrial control systems; unauthorized commands could lead to unsafe operational states or equipment damage. Confidentiality breaches could expose sensitive operational data, while integrity and availability impacts could disrupt services. Given the permanent nature of the open WiFi network, attackers do not need to wait for initial setup phases, increasing the window of exposure. This vulnerability could also facilitate lateral movement within a network if the device is connected to broader enterprise or industrial networks. The critical CVSS score underscores the urgency for European organizations to address this issue promptly to avoid potential exploitation.
