Technical Analysis

CVE-2025-4383 is a critical vulnerability identified in the Wi-Fi Cloud Hotspot product developed by Art-in Bilişim Teknolojileri ve Yazılım Hizm. Tic. Ltd. Şti. This vulnerability stems from CWE-307, which concerns improper restriction of excessive authentication attempts. Specifically, the affected versions of Wi-Fi Cloud Hotspot (all versions prior to 30.05.2025) do not adequately limit the number of authentication attempts, allowing an attacker to perform brute force or automated authentication abuse without being blocked or throttled. The vulnerability enables authentication bypass and abuse, potentially allowing attackers to gain unauthorized access to the hotspot management interface or user sessions. The CVSS v3.1 base score is 9.3 (critical), reflecting the vulnerability's network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), scope change (S:C), no confidentiality impact (C:N), low integrity impact (I:L), and high availability impact (A:H). The scope change indicates that the vulnerability affects components beyond the initially vulnerable system, potentially impacting connected systems or services. The high availability impact suggests that exploitation could lead to denial of service or disruption of hotspot services. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability was published on June 24, 2025, with the reservation date on May 6, 2025, by TR-CERT, indicating a Turkish origin of the vendor and initial reporting. The Wi-Fi Cloud Hotspot product is typically used to provide managed wireless internet access in public or semi-public environments, such as cafes, hotels, airports, and other venues requiring controlled Wi-Fi access. The lack of restriction on authentication attempts means attackers can systematically try credentials or session tokens to gain unauthorized access or disrupt service availability.

Potential Impact

For European organizations, the impact of CVE-2025-4383 can be significant, especially for businesses and public institutions relying on Wi-Fi Cloud Hotspot for guest or customer internet access. Unauthorized access through authentication bypass could lead to misuse of network resources, unauthorized data access, or lateral movement within internal networks if the hotspot is connected to broader infrastructure. The high availability impact means attackers could launch denial-of-service attacks by overwhelming the authentication system, causing service outages that affect customer experience and operational continuity. This is particularly critical for sectors such as hospitality, transportation hubs, retail, and public services, where Wi-Fi access is integral to customer engagement and operational workflows. Additionally, compromised hotspots could be leveraged as entry points for further attacks, including malware distribution or interception of user traffic, raising privacy and regulatory compliance concerns under GDPR. The scope change in the CVSS vector suggests that exploitation might affect other connected systems or services, amplifying the risk. Given the vendor's Turkish origin and the product's deployment in various markets, European organizations using this hotspot solution or similar configurations are at risk if they have not applied mitigations or updates.

Mitigation Recommendations

1. Immediate deployment of any available vendor patches or updates once released is critical. Since no patch links are currently provided, organizations should maintain close communication with the vendor for updates. 2. Implement network-level rate limiting and intrusion prevention systems (IPS) to detect and block excessive authentication attempts targeting the hotspot. 3. Employ multi-factor authentication (MFA) for hotspot management interfaces to reduce the risk of authentication bypass. 4. Segment the hotspot network from critical internal networks to limit potential lateral movement if the hotspot is compromised. 5. Monitor authentication logs for unusual patterns indicative of brute force or automated attacks and trigger alerts for rapid response. 6. Consider deploying web application firewalls (WAF) or dedicated hotspot security appliances that can add an additional layer of authentication attempt restrictions. 7. Educate staff managing the hotspot infrastructure about the vulnerability and encourage prompt incident reporting. 8. If possible, temporarily disable or restrict hotspot access during periods of high attack risk until patches are applied. 9. Review and harden default configurations, including disabling unnecessary services and enforcing strong password policies. 10. Conduct penetration testing and vulnerability assessments focused on hotspot authentication mechanisms to identify residual weaknesses.
