Attack Complexity: Low

User Interaction: None
Scope: Unchanged
Confidentiality: None
Integrity: High
Availability: High

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: 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 15 Mar 2024
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 2026-10-26.

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

1. Monitor Sciener’s official channels for firmware updates addressing CVE-2023-7006 and apply patches promptly once available. 2. Implement network segmentation to isolate smart locks from general network traffic, limiting exposure to potential attackers. 3. Deploy intrusion detection systems (IDS) or anomaly detection tools to monitor for unusual patterns of challenge requests or repeated authentication attempts targeting the locks. 4. Enforce strict access controls on management interfaces and restrict remote access to the locks to trusted networks or VPNs. 5. If possible, configure rate limiting or throttling mechanisms at the network level to reduce the feasibility of brute force attacks. 6. Conduct regular security audits of IoT devices and integrate smart lock security into broader physical security policies. 7. Educate facility managers and security personnel about the vulnerability and signs of potential exploitation. 8. Consider alternative or additional physical security measures (e.g., mechanical locks or secondary authentication) until the vulnerability is fully mitigated. 9. Maintain logs of lock access attempts and review them regularly for suspicious activity. 10. Engage with Sciener support for guidance and potential interim mitigation strategies.

Description

The unlockKey character in a lock using Sciener firmware can be brute forced through repeated challenge requests, compromising the locks integrity.

Impact

The primary impact of CVE-2023-7006 on European organizations lies in the compromise of physical security controls provided by the Sciener Kontrol Lux smart locks. Unauthorized brute forcing of the unlockKey can lead to unauthorized entry into secured premises, risking theft, espionage, or sabotage. This is particularly critical for sectors such as residential housing, hospitality, commercial real estate, and facilities management where these locks are deployed. The integrity and availability of the locking mechanism are directly affected, potentially causing operational disruptions and safety hazards. For organizations relying on these locks for access control, the vulnerability undermines trust in IoT security solutions and may lead to increased costs related to incident response, physical security upgrades, and reputational damage. Given the remote exploitability without authentication, attackers can operate stealthily, increasing the risk of unnoticed breaches. European data protection regulations, such as GDPR, may also be implicated if unauthorized physical access leads to data breaches or loss of personal data. The lack of known exploits currently provides a window for proactive mitigation, but the critical severity demands immediate attention.
