CVE-2025-5248 is a critical SQL Injection vulnerability identified in version 1.0 of the PHPGurukul Company Visitor Management System. The flaw exists in an unspecified function within the /bwdates-reports-details.php file, where the 'fromdate' and 'todate' parameters are improperly sanitized. This lack of input validation allows an attacker to inject malicious SQL code remotely without requiring authentication or user interaction. Exploiting this vulnerability could enable an attacker to manipulate backend database queries, potentially leading to unauthorized data access, data modification, or deletion. The vulnerability is remotely exploitable over the network, increasing its risk profile. Although the CVSS 4.0 score is 6.9 (medium severity), the classification as critical in the description suggests the potential for significant impact if exploited. The vulnerability affects only version 1.0 of the product, and no patches or mitigations have been publicly disclosed yet. No known exploits are currently observed in the wild, but public disclosure of the exploit code increases the risk of exploitation attempts.

For European organizations using PHPGurukul Company Visitor Management System 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of visitor management data. Exploitation could lead to unauthorized access to sensitive visitor logs, personal information, and potentially other connected systems if the database contains integrated data. This could result in privacy breaches violating GDPR regulations, leading to legal and financial repercussions. Additionally, data manipulation or deletion could disrupt visitor tracking operations, impacting physical security management. The remote and unauthenticated nature of the exploit increases the likelihood of attacks, especially in organizations with internet-facing visitor management portals. The medium CVSS score reflects moderate ease of exploitation and impact, but the critical classification and potential for data compromise warrant urgent attention.

European organizations should immediately audit their environments to identify any deployments of PHPGurukul Company Visitor Management System version 1.0. As no official patches are currently available, organizations should implement the following specific mitigations: 1) Restrict network access to the visitor management system, limiting it to trusted internal networks or VPNs to reduce exposure. 2) Employ web application firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting 'fromdate' and 'todate' parameters. 3) Conduct code reviews and apply manual input validation and parameterized queries in the affected PHP file if source code access is available. 4) Monitor logs for suspicious query patterns or unusual database errors indicative of injection attempts. 5) Plan for an upgrade or replacement of the vulnerable system with a patched or alternative solution as soon as a fix is released. 6) Educate IT and security teams about this vulnerability to ensure rapid response to any exploitation attempts.
