CVE-2025-39445 is a critical SQL Injection vulnerability (CWE-89) found in the highwarden Super Store Finder product, affecting versions up to 7.2. This vulnerability arises due to improper neutralization of special elements used in SQL commands, allowing an unauthenticated attacker to inject malicious SQL code remotely over the network without any user interaction. The CVSS 3.1 base score of 9.3 reflects the high severity, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction (UI:N). The scope is changed (S:C), indicating that exploitation can affect resources beyond the vulnerable component. The impact on confidentiality is high (C:H), while integrity is not impacted (I:N), and availability impact is low (A:L). This suggests that an attacker can extract sensitive data from the backend database but cannot modify or delete data or cause significant denial of service. The vulnerability is present in the Super Store Finder application, a tool commonly used by retail and commercial businesses to locate stores and services. The lack of available patches at the time of publication increases the urgency for mitigation. Although no known exploits are currently reported in the wild, the ease of exploitation and critical impact make this a significant threat that could be weaponized quickly once exploit code becomes available. The vulnerability allows attackers to bypass authentication and extract sensitive information such as customer data, business intelligence, or internal configurations, potentially leading to data breaches and compliance violations.

For European organizations using highwarden Super Store Finder, this vulnerability poses a substantial risk to the confidentiality of sensitive customer and business data. Retailers and service providers relying on this software could face data breaches exposing personal data protected under GDPR, leading to regulatory fines and reputational damage. The ability to remotely exploit this vulnerability without authentication or user interaction means attackers can operate stealthily and at scale. Data exfiltration could include customer locations, contact details, and transaction histories, which are valuable for identity theft and fraud. Additionally, the compromise of internal business intelligence could undermine competitive advantage. Even though integrity and availability impacts are limited, the confidentiality breach alone is critical. European organizations may also face legal consequences under data protection laws if they fail to secure their systems against such vulnerabilities. The threat is amplified by the lack of patches, requiring immediate defensive measures to prevent exploitation.

1. Immediate deployment of Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting Super Store Finder endpoints. 2. Conduct thorough input validation and sanitization on all user-supplied data fields within the application, employing parameterized queries or prepared statements to prevent injection. 3. Restrict database user permissions to the minimum necessary, avoiding use of high-privilege accounts by the application to limit potential data exposure. 4. Monitor network traffic and application logs for unusual query patterns or spikes in database errors indicative of attempted SQL injection attacks. 5. Implement network segmentation to isolate the Super Store Finder application and its database from other critical systems. 6. Engage with the vendor highwarden for timely patch releases and apply updates as soon as they become available. 7. Perform regular security assessments and penetration testing focused on injection flaws to identify and remediate similar vulnerabilities proactively. 8. Educate development and operations teams on secure coding practices and the risks of SQL injection to prevent recurrence.
