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: High: A successful attack depends on conditions beyond the attacker's control. That is, a successful attack cannot be accomplished at will, but requires the attacker to invest in some measurable amount of effort in preparation or execution against the vulnerable component before a successful attack can be expected. For example, a successful attack may require an attacker to: gather knowledge about the environment in which the vulnerable target/component exists; prepare the target environment to improve exploit reliability; or inject themselves into the logical network path between the target and the resource requested by the victim in order to read and/or modify network communications (e.g., a man in the middle attack).
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: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
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: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploited in the wildExploited: 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

Organizations should immediately review their UniFi Network Application deployments to determine if they are running affected versions (9.2.87 or earlier) and whether both 802.1X/MAC Authentication and VPN services share the same RADIUS profile. As no official patches are currently linked, temporary mitigations include segregating RADIUS profiles for WiFi and VPN services to prevent cross-authentication via MAC addresses. Network administrators should enforce stronger authentication methods that do not rely solely on MAC addresses, such as certificate-based 802.1X authentication, and disable MAC Authentication where possible. Monitoring network logs for unusual authentication attempts or MAC address anomalies can help detect exploitation attempts. Additionally, restricting network access by implementing network segmentation and zero-trust principles can limit the impact of any unauthorized access. Organizations should stay alert for official patches or updates from Ubiquiti and apply them promptly once available.

Description

A misconfigured query in UniFi Network (v9.1.120 and earlier) could allow users to authenticate to Enterprise WiFi or VPN Server (l2tp and OpenVPN) using a device’s MAC address from 802.1X or MAC Authentication, if both services are enabled and share the same RADIUS profile.

Impact

For European organizations, this vulnerability poses a significant risk to network security, particularly in sectors relying heavily on secure wireless and VPN access, such as finance, healthcare, government, and critical infrastructure. Unauthorized access via MAC address spoofing could lead to exposure of sensitive data, unauthorized lateral movement within networks, and potential breaches of compliance with GDPR and other data protection regulations. The confidentiality impact is high as attackers could access internal resources without proper authentication. Although integrity and availability are not directly affected, the unauthorized access could facilitate further attacks that compromise these aspects. The medium severity score reflects the high confidentiality risk balanced against the high attack complexity, meaning exploitation is not trivial but feasible for skilled attackers. Given the widespread use of Ubiquiti UniFi products in European enterprises and SMBs, this vulnerability could have broad implications if exploited.
