CVE-2025-4553 is a SQL Injection vulnerability identified in version 1.0 of the PHPGurukul Apartment Visitors Management System, specifically within the /admin/bwdates-reports-details.php file. The vulnerability arises due to improper sanitization or validation of the 'fromdate' and 'todate' input parameters, which are used in SQL queries. An attacker can manipulate these parameters remotely without requiring authentication or user interaction, injecting malicious SQL code that could alter the intended database queries. 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, categorized as medium severity, reflecting the ease of exploitation (network accessible, no privileges or user interaction needed) but with limited impact on confidentiality, integrity, and availability (each rated low). No known exploits are currently reported in the wild, and no patches have been published yet. The vulnerability affects only version 1.0 of the product, which is a niche visitor management system used primarily in apartment complexes to track visitor entries and reports.

For European organizations using the PHPGurukul Apartment Visitors Management System version 1.0, this vulnerability poses a risk of unauthorized access to sensitive visitor data, which may include personally identifiable information (PII) of residents and visitors. Exploitation could lead to data breaches, undermining privacy compliance obligations under regulations such as the GDPR. Additionally, attackers could manipulate or delete records, disrupting visitor management operations and potentially causing safety or security issues within residential complexes. Although the product is specialized and likely has limited deployment in Europe, organizations relying on it without timely updates or mitigations could face reputational damage and regulatory penalties if exploited. The remote, unauthenticated nature of the vulnerability increases the risk of automated attacks or scanning by threat actors targeting exposed management interfaces.

Given the absence of an official patch, European organizations should implement immediate compensating controls. These include restricting network access to the /admin/bwdates-reports-details.php endpoint via firewall rules or VPN-only access to limit exposure. Input validation and sanitization should be enforced at the web application firewall (WAF) level to detect and block suspicious SQL injection payloads targeting the 'fromdate' and 'todate' parameters. Organizations should monitor logs for unusual query patterns or repeated access attempts to this endpoint. If possible, upgrade or migrate to a newer, patched version of the software once available. Additionally, conduct a thorough audit of visitor data integrity and access logs to detect any prior exploitation. Educate administrative users on the risks and ensure strong authentication mechanisms are in place to reduce overall attack surface.
