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

Disclosed: evidence found.
CVE published 1 Sep 2025
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 2026-10-25.

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 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 to identify any SkyBridge BASIC MB-A130 devices running version 1.5.8 or earlier. for official patches or firmware updates is critical. In the interim, network segmentation should be enforced to isolate these devices from critical infrastructure and sensitive data environments. Implement strict access controls and monitoring on network segments containing these devices to detect anomalous command execution or unauthorized access attempts. Employ intrusion detection/prevention systems (IDS/IPS) with signatures or heuristics capable of identifying command injection attempts. Disable any unnecessary services or remote management interfaces on the affected devices to reduce the attack surface. Additionally, consider deploying application-layer firewalls or proxy solutions that can sanitize inputs or block suspicious commands targeting these devices. Regularly review logs for signs of exploitation attempts and prepare incident response plans specific to this vulnerability.

Description

Improper neutralization of special elements used in an OS command ('OS Command Injection') issue exists in SkyBridge BASIC MB-A130 Ver.1.5.8 and earlier. If exploited, a remote unauthenticated attacker may execute arbitrary OS commands with root privileges.

Impact

For European organizations, exploitation of this vulnerability could result in complete system compromise of the affected devices, leading to unauthorized access to sensitive data, disruption of business-critical operations, and potential lateral movement within internal networks. Since the attacker gains root privileges remotely without authentication, the risk of widespread damage is high. This could affect sectors relying on these devices for network infrastructure or industrial control, including manufacturing, logistics, and retail. The impact extends to regulatory compliance issues under GDPR if personal data is exposed or integrity is compromised. Additionally, operational downtime caused by exploitation could lead to financial losses and reputational damage. The lack of current known exploits does not diminish the urgency, as threat actors may develop exploits rapidly once the vulnerability details are public.
