CVE-2025-9047 is a SQL Injection vulnerability identified in version 1.0 of the projectworlds Visitor Management System, specifically in the /visitor_out.php file. The vulnerability arises from improper sanitization or validation of the 'rid' parameter, which is susceptible to malicious input manipulation. An attacker can remotely exploit this flaw without any authentication or user interaction, injecting crafted SQL commands that the backend database executes. This can lead to unauthorized data access, modification, or deletion, potentially compromising the confidentiality, integrity, and availability of the system's data. The vulnerability has a CVSS 4.0 base score of 6.9, indicating a medium severity level. The attack vector is network-based (AV:N), requiring no privileges (PR:N), no user interaction (UI:N), and no scope change (SI:N). The impact on confidentiality, integrity, and availability is low to medium (VC:L, VI:L, VA:L), suggesting partial but significant compromise potential. Although no public exploits are currently known in the wild, the disclosure of the exploit code increases the risk of exploitation. The vulnerability affects only version 1.0 of the product, and no official patches or mitigations have been published yet. This SQL Injection vulnerability is critical because visitor management systems often handle sensitive visitor data and access logs, which if compromised, can lead to privacy violations and unauthorized physical or logical access to facilities.

For European organizations using projectworlds Visitor Management System 1.0, this vulnerability poses a significant risk. Visitor management systems are commonly deployed in corporate offices, government buildings, healthcare facilities, and educational institutions across Europe to track and control visitor access. Exploitation could allow attackers to extract sensitive visitor information, manipulate visitor logs, or disrupt visitor processing workflows. This could lead to privacy breaches violating GDPR regulations, reputational damage, and potential physical security risks if attackers manipulate visitor access records. The medium severity rating indicates that while the vulnerability may not lead to full system takeover, it still allows meaningful unauthorized data access and modification. Organizations in sectors with strict compliance requirements (e.g., finance, healthcare, government) are particularly vulnerable to regulatory penalties if such data breaches occur. Additionally, the remote and unauthenticated nature of the exploit increases the attack surface, making it easier for threat actors to target these systems from outside the network perimeter.

Given the absence of official patches, European organizations should implement immediate compensating controls. First, restrict network access to the Visitor Management System, allowing only trusted internal IP ranges to communicate with the /visitor_out.php endpoint. Deploy Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the 'rid' parameter. Conduct thorough input validation and sanitization on all user-supplied parameters, especially 'rid', to neutralize malicious payloads. If possible, upgrade or replace the vulnerable version 1.0 with a newer, patched version once available. Regularly monitor logs for suspicious queries or unusual database activity indicative of exploitation attempts. Additionally, conduct security awareness training for administrators to recognize and respond to potential exploitation signs. Finally, consider isolating the visitor management system within a segmented network zone to limit lateral movement in case of compromise.
