CVE-2025-4548 is a critical SQL Injection vulnerability identified in version 1.0 of the Campcodes Online Food Ordering System. The vulnerability resides in the /routers/router.php file, specifically involving the manipulation of the 'Username' argument. An attacker can remotely exploit this flaw without requiring authentication or user interaction, by injecting malicious SQL code through the Username parameter. This can lead to unauthorized access or modification of the backend database, potentially exposing sensitive customer data, order information, or administrative credentials. The CVSS 4.0 score is 6.9, categorized as medium severity, reflecting the ease of remote exploitation (AV:N), no privileges or user interaction required, but with limited impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). Although no known exploits are currently active in the wild, the public disclosure of the vulnerability increases the risk of exploitation. The absence of available patches or mitigation guidance from the vendor further elevates the threat. SQL Injection vulnerabilities are among the most dangerous web application flaws, often leading to data breaches, data loss, or full system compromise if leveraged effectively. Given the nature of the product—a food ordering system—compromise could disrupt business operations, damage customer trust, and lead to regulatory penalties under data protection laws.

For European organizations using the Campcodes Online Food Ordering System 1.0, this vulnerability poses a significant risk to both operational continuity and data security. Exploitation could allow attackers to extract personal customer data, including names, contact details, and order histories, potentially violating GDPR requirements and resulting in heavy fines. Integrity of order data could be compromised, leading to fraudulent orders or financial losses. Availability impacts could disrupt service, harming reputation and revenue streams. Since the vulnerability is remotely exploitable without authentication, attackers can target these systems en masse, increasing the likelihood of widespread impact. Additionally, food service providers are critical infrastructure in many regions, and disruption could have broader societal effects. The lack of patches means organizations must rely on compensating controls, increasing operational complexity and risk.

1. Immediate implementation of Web Application Firewalls (WAFs) with rules specifically designed to detect and block SQL Injection attempts targeting the Username parameter in /routers/router.php. 2. Conduct thorough input validation and sanitization on all user-supplied data, especially the Username field, using parameterized queries or prepared statements to prevent injection. 3. Restrict database user permissions to the minimum necessary to limit the impact of a successful injection. 4. Monitor logs for unusual database queries or access patterns indicative of exploitation attempts. 5. Isolate the vulnerable system within the network and limit external exposure until a vendor patch or update is available. 6. Engage with the vendor for timely patch releases and apply updates as soon as they become available. 7. Educate development and operations teams on secure coding practices to prevent similar vulnerabilities in future releases.
