CVE-2025-63525 is a critical security vulnerability identified in Blood Bank Management System version 1.0. The issue arises from improper access control in the delete.php endpoint, which allows authenticated users with low privileges to perform unauthorized actions with escalated privileges. Specifically, an attacker who has some level of authenticated access can craft a malicious request to the delete.php script to delete or manipulate data that should be restricted to higher privilege users. The vulnerability is classified under CWE-284 (Improper Access Control), indicating a failure to enforce correct privilege checks. The CVSS 3.1 base score is 9.6, reflecting high impact on confidentiality and integrity, with no user interaction required and low attack complexity. The scope is changed, meaning the vulnerability affects resources beyond the initially compromised component. Although no known exploits are currently reported in the wild, the critical severity and ease of exploitation make this a significant threat. The lack of available patches at the time of publication increases the urgency for organizations to implement compensating controls. This vulnerability could lead to unauthorized deletion of critical blood bank data, potentially disrupting healthcare operations and compromising patient safety.

For European organizations, particularly those in the healthcare sector, this vulnerability poses a severe risk. Blood banks manage highly sensitive and critical data related to blood donations, inventory, and patient transfusion records. Exploitation could lead to unauthorized deletion or alteration of this data, resulting in operational disruptions, delays in medical procedures, and potential harm to patients. Confidentiality breaches could expose personal health information, violating GDPR and other data protection regulations, leading to legal and financial consequences. Integrity loss undermines trust in healthcare services and could cause cascading effects in hospital supply chains. The availability of the system could also be indirectly affected if data corruption requires system downtime for recovery. Given the critical nature of healthcare infrastructure, this vulnerability could be leveraged by threat actors aiming to cause disruption or gain strategic advantage, especially in countries with advanced healthcare IT systems.

Until an official patch is released, European healthcare organizations should implement strict access control reviews to ensure that only authorized personnel have access to sensitive functionalities like delete.php. Employ network segmentation to isolate the blood bank management system from broader enterprise networks, reducing exposure. Monitor and log all access to critical endpoints to detect suspicious activity early. Implement multi-factor authentication (MFA) to reduce the risk of compromised credentials being used to exploit this vulnerability. Conduct regular security audits and penetration testing focused on access control mechanisms. If possible, apply web application firewalls (WAFs) with custom rules to block or alert on suspicious requests targeting delete.php. Educate staff on the importance of credential security and monitor for unusual authentication patterns. Prepare incident response plans specifically addressing potential exploitation scenarios involving this system. Finally, maintain close communication with the vendor for timely patch deployment once available.
