CVE-2025-4764 identifies a critical SQL Injection vulnerability in the Hotel Guest Hotspot software developed by Aida Computer Information Technology Inc. This vulnerability stems from improper neutralization of special characters in SQL commands (CWE-89), which allows an attacker to inject malicious SQL code into the backend database queries. The affected versions include all releases up to 22012026. The vulnerability can be exploited remotely by an attacker with low privileges (PR:L) and does not require user interaction (UI:N), but does require network access to the application (AV:A). Successful exploitation can lead to complete compromise of the database confidentiality, integrity, and availability, enabling data exfiltration, unauthorized data modification, or denial of service. The vendor was notified early but has not issued any patches or advisories. No known exploits are currently observed in the wild, but the high CVSS score of 8.0 reflects the significant risk posed by this flaw. The vulnerability affects hospitality environments where the Hotel Guest Hotspot product is deployed, potentially exposing sensitive guest and operational data. The lack of vendor response and absence of patches increases the urgency for organizations to implement compensating controls.

The impact of CVE-2025-4764 is substantial for organizations using the Hotel Guest Hotspot product, particularly in the hospitality sector. Exploitation can lead to unauthorized access to sensitive guest information, including personal and payment data, resulting in privacy violations and regulatory non-compliance. Attackers could manipulate or delete critical data, disrupting hotel operations and guest services. The vulnerability also opens pathways for attackers to pivot within internal networks, potentially compromising additional systems. Given the product's role in managing guest network access, availability impacts could degrade customer experience and damage brand reputation. The high severity and ease of exploitation without user interaction increase the likelihood of targeted attacks. Organizations worldwide relying on this product face risks of data breaches, financial losses, and operational downtime.

In the absence of vendor patches, organizations should implement immediate compensating controls. Network segmentation should isolate the Hotel Guest Hotspot system from critical internal networks to limit lateral movement. Deploy web application firewalls (WAFs) with custom rules to detect and block SQL injection payloads targeting the vulnerable endpoints. Conduct thorough input validation and sanitization on all user-supplied data before it reaches the database layer. Monitor database logs and network traffic for unusual query patterns or spikes indicative of exploitation attempts. Restrict access to the management interfaces to trusted IP addresses only and enforce strong authentication mechanisms. Regularly back up databases and test restoration procedures to mitigate data loss risks. Engage with the vendor for updates and consider alternative solutions if remediation is delayed. Finally, maintain up-to-date threat intelligence to detect emerging exploits targeting this vulnerability.
