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: 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: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

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

1. Implement strict network segmentation to isolate the administrative interface of Uniway routers from untrusted networks, limiting access to known and secured management stations. 2. Employ VPNs or secure tunnels with strong authentication for administrative access rather than relying on IP-based controls. 3. Monitor network traffic for unusual IP spoofing or access attempts targeting router management interfaces. 4. Use network intrusion detection/prevention systems (IDS/IPS) to detect and block suspicious activities related to IP spoofing or unauthorized access attempts. 5. Regularly audit router configurations and logs to identify unauthorized changes or access patterns. 6. Where possible, replace or upgrade affected Uniway Router devices to models or firmware versions that do not rely on IP-based authentication. 7. Engage with Uniway or third-party security providers for potential custom patches or mitigations if official updates remain unavailable. 8. Educate network administrators about the risks of IP-based authentication and encourage best practices for secure device management.

Description

A vulnerability was found in Uniway Router 2.0. It has been declared as critical. This vulnerability affects unknown code of the component Administrative Web Interface. The manipulation leads to reliance on ip address for authentication. The attack can be initiated remotely. The complexity of an attack is rather high. The exploitation appears to be difficult. The exploit has been disclosed to the public and may be used. VDB-249766 is the identifier assigned to this vulnerability. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.

Impact

For European organizations using Uniway Router 2.0, this vulnerability poses a risk of unauthorized administrative access to network infrastructure. Such access could allow attackers to alter router configurations, intercept or redirect traffic, or disrupt network availability. This could lead to data breaches, loss of network integrity, and potential service outages. Critical infrastructure operators, enterprises with sensitive data, and public sector organizations relying on these routers for network management could face operational disruptions and compliance issues under GDPR if personal data confidentiality is compromised. The medium severity and high attack complexity somewhat limit immediate widespread exploitation, but targeted attacks against high-value networks remain a concern. The absence of vendor patches increases the window of exposure, especially in environments lacking compensating controls like strict network segmentation or robust monitoring.

Summary

CVE-2023-7211 is a medium-severity vulnerability affecting Uniway Router version 2.0, specifically within its Administrative Web Interface component. The core issue is a reliance on IP address-based authentication, classified under CWE-291 (Reliance on IP Address for Authentication). This means that the router's administrative interface trusts the source IP address as a factor for granting access, which is inherently insecure. An attacker who can spoof or manipulate their IP address to appear as a trusted source could potentially bypass authentication controls and gain unauthorized administrative access. The vulnerability is remotely exploitable without requiring user interaction or prior authentication, but the attack complexity is rated as high, indicating that exploitation demands advanced skills or specific conditions. The CVSS 3.1 base score is 5.6 (medium), reflecting limited confidentiality, integrity, and availability impacts, and the difficulty of exploitation. Although no known exploits are currently active in the wild, the public disclosure of the vulnerability increases the risk of future exploitation attempts. The lack of vendor response and patch availability leaves affected devices exposed, especially in environments where network segmentation or IP filtering is weak or absent. This vulnerability undermines the security model of the router’s administrative interface by trusting IP addresses, which can be spoofed or manipulated in various network scenarios, such as within compromised local networks or via advanced routing attacks.
