CVE-2025-63525 is a critical security vulnerability identified in Blood Bank Management System version 1.0. The flaw exists in the delete.php endpoint, which processes deletion requests. Authenticated attackers with low-level privileges can craft specific requests to this endpoint to perform actions beyond their authorized scope, effectively escalating their privileges. This vulnerability allows attackers to delete or manipulate sensitive data related to blood bank operations, potentially compromising patient information and disrupting critical healthcare services. The CVSS 3.1 base score of 9.6 reflects the vulnerability's high impact on confidentiality and integrity, with no user interaction required and the ability to be exploited remotely over the network. Although no known exploits are currently reported in the wild, the vulnerability's characteristics make it a prime target for attackers aiming to disrupt healthcare infrastructure or steal sensitive data. The lack of available patches at the time of disclosure necessitates immediate risk mitigation through access controls and monitoring. Given the critical role of blood bank systems in healthcare, exploitation could lead to severe consequences including data breaches, loss of trust, and operational downtime.

For European organizations, particularly those in the healthcare sector, this vulnerability poses a significant threat. Exploitation could lead to unauthorized deletion or alteration of sensitive patient and blood inventory data, compromising patient safety and violating data protection regulations such as GDPR. The integrity and availability of blood bank services could be severely impacted, potentially delaying critical medical procedures. Healthcare providers relying on this system may face operational disruptions and reputational damage. Additionally, the breach of confidential health information could result in legal penalties and loss of patient trust. The critical severity and ease of exploitation make this vulnerability a high-priority risk for European healthcare institutions, especially those with interconnected IT environments where lateral movement could amplify the damage.

To mitigate this vulnerability, European healthcare organizations should immediately restrict access to the delete.php endpoint to only highly trusted and necessary users, ideally through network segmentation and firewall rules. Implement strict authorization checks to ensure that only users with appropriate privileges can perform deletion operations. Monitor logs for unusual or unauthorized deletion requests and establish alerting mechanisms. Employ multi-factor authentication to reduce the risk of compromised credentials being used for exploitation. Until an official patch is released, consider deploying web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting delete.php. Conduct thorough security audits of the Blood Bank Management System and related components to identify and remediate other potential weaknesses. Finally, prepare an incident response plan tailored to healthcare data breaches to minimize impact in case of exploitation.
