CVE-2025-4764 identifies an SQL Injection vulnerability in the Hotel Guest Hotspot product by Aida Computer Information Technology Inc., affecting versions up to 22012026. The vulnerability arises from improper neutralization of special characters in SQL commands (CWE-89), enabling an attacker to inject malicious SQL statements. The CVSS 3.1 score is 8.0 (high), with an attack vector of adjacent network (AV:A), low attack complexity (AC:L), requiring low privileges (PR:L), no user interaction (UI:N), and impacting confidentiality, integrity, and availability (C:H/I:H/A:H). This means an attacker with limited access to the same network segment as the device can exploit the flaw to execute arbitrary SQL commands, potentially extracting sensitive data, modifying or deleting records, or disrupting service. The vendor was contacted but did not respond, and no patches or mitigations have been released. The vulnerability affects a critical component in hospitality environments—guest Wi-Fi hotspot management—where compromised systems could expose guest data or disrupt network services. The lack of vendor response and absence of known exploits in the wild suggest the vulnerability is newly disclosed but poses a significant risk if weaponized. Technical mitigation is complicated by the absence of patches, requiring defensive controls at the network and application layers.

For European organizations, especially those in the hospitality industry using Aida Computer Information Technology Inc.'s Hotel Guest Hotspot, this vulnerability poses a significant risk. Exploitation can lead to unauthorized access to sensitive guest information, including personal and payment data, violating GDPR and other privacy regulations. Integrity of hotspot configuration and logs can be compromised, enabling attackers to manipulate network access or cover tracks. Availability impacts could disrupt guest internet services, damaging reputation and causing operational losses. The adjacent network attack vector means attackers need some network proximity, which is plausible in public or semi-public hotel environments. The lack of vendor patches increases risk exposure duration. European hotels and service providers relying on this product must consider the potential for regulatory penalties, customer trust erosion, and operational disruptions. Additionally, attackers could leverage this vulnerability as a foothold for lateral movement within hotel networks, threatening broader organizational infrastructure.

Given the absence of vendor patches, European organizations should implement immediate compensating controls. These include strict network segmentation to isolate the Hotel Guest Hotspot devices from critical internal systems and sensitive data stores. Employ network access control (NAC) to restrict which devices can connect to the hotspot management network. Deploy intrusion detection/prevention systems (IDS/IPS) with signatures or anomaly detection tuned to identify SQL injection attempts targeting the hotspot. Regularly audit and monitor database logs for suspicious queries or unauthorized access patterns. If possible, replace or upgrade the affected product to a more secure alternative or a version not affected by this vulnerability. Conduct thorough security assessments of the hotspot environment and apply principle of least privilege to all accounts interacting with the database. Educate staff on the risks and signs of exploitation. Finally, maintain close monitoring of threat intelligence sources for any emerging exploits or vendor updates.
