CVE-2026-10249: SQL Injection in itsourcecode Online Blood Bank Management System 1.0

Technical summary

CVE-2026-10249 is a remote, unauthenticated SQL injection flaw in the /admin/viewrequest.php endpoint of itsourcecode Online Blood Bank Management System 1.0. The vulnerability arises from insufficient input validation on the ID parameter, permitting attackers to craft malicious SQL queries that execute within the database context. The affected CWEs (CWE-74: Improper Neutralization of Special Elements in Output and CWE-89: Improper Neutralization of Special Elements used in an SQL Command) indicate both direct SQL injection and potential output encoding failures. The CVSS 3.1 score of 7.3 (HIGH) reflects the network-accessible nature, low attack complexity, and moderate impact on confidentiality, integrity, and availability.

Business impact

Blood bank management systems handle critical patient health information and blood inventory critical to transfusion operations. A successful SQL injection attack could expose personally identifiable information (PII), blood type records, donation history, and potentially compromise blood product inventory tracking. For healthcare organizations, this translates to regulatory violations (HIPAA, GDPR), loss of patient trust, operational disruption during blood shortages, and potential harm if incompatible blood is administered due to corrupted records. Ransomware actors or competitors may leverage this flaw to exfiltrate data or lock critical systems.

Affected systems

itsourcecode Online Blood Bank Management System version 1.0 is directly affected. Organizations running this specific version in production environments, whether on-premises or cloud-hosted, face immediate risk. The vulnerability does not require authentication, making every internet-facing instance a potential target. Verify your deployment version against vendor documentation to confirm scope within your organization.

Exploitability

This vulnerability presents high exploitability risk. The attack requires no authentication, no special configuration, and minimal technical sophistication—SQL injection at this attack surface is well-understood and readily automated. Publicly available exploits lower the barrier to entry for opportunistic attackers and organized threat actors. Exploitation can occur immediately upon network exposure without user interaction.

Remediation

Upgrade itsourcecode Online Blood Bank Management System to a patched version released by the vendor. Verify the patch version and release notes against the official vendor advisory to confirm SQL injection remediation. If immediate patching is unavailable, implement network-level controls: restrict /admin/ endpoint access to trusted IP ranges via firewall rules, disable public internet access, and enforce VPN or bastion host requirements. Deploy Web Application Firewall (WAF) rules to detect and block common SQL injection payloads targeting the ID parameter.

Patch guidance

Contact itsourcecode or consult their official security advisory for the specific patched version addressing CVE-2026-10249. After patching, conduct a full application restart and verify through security testing that the ID parameter no longer permits SQL injection. If the vendor has not released a patch, request an expedited security update and implement compensating controls immediately. Test patches in a non-production environment first to ensure compatibility with your blood bank workflows.

Detection guidance

Monitor HTTP access logs for /admin/viewrequest.php requests containing suspicious patterns in the ID parameter, such as SQL keywords (UNION, SELECT, OR 1=1), comment sequences (--), or encoded payloads (%27, %3D). Implement intrusion detection signatures targeting SQL injection attempts. Audit database query logs for unexpected administrative queries or multi-statement executions originating from the application user account. Alert on repeated failed query attempts, which may indicate active exploitation or reconnaissance.

Why prioritize this

This vulnerability merits immediate remediation despite the absence of KEV designation. The combination of unauthenticated remote attack, public exploit availability, HIGH CVSS score, and the critical nature of blood bank data creates urgent business and compliance risk. Healthcare organizations face regulatory scrutiny and potential operational harm from blood inventory corruption. The low technical barrier to exploitation means active scanning and attack attempts are likely underway.

Risk score, explained

The CVSS 3.1 score of 7.3 (HIGH) reflects a network-accessible, unauthenticated attack with low complexity, causing partial disclosure and modification of data. This score appropriately captures the severity for a general audience but understates the organizational risk for healthcare entities, where patient data exposure and operational system compromise carry elevated regulatory and reputational consequences. Security teams should weight this vulnerability as CRITICAL within healthcare environments and apply fastest-track remediation timelines.
