CVE-2025-63525 Overview
CVE-2025-63525 is a privilege escalation vulnerability in Shridharshukl Blood Bank Management System 1.0. The flaw resides in the delete.php endpoint, which fails to enforce proper access control. Authenticated attackers can issue crafted requests to perform actions reserved for higher-privileged accounts. The weakness maps to [CWE-284] Improper Access Control and affects the confidentiality, integrity, and availability of stored blood bank records.
Critical Impact
Authenticated users can escalate privileges and delete or manipulate records belonging to other users or administrators by sending crafted requests to delete.php.

Technical Details for CVE-2025-63525
Vulnerability Analysis
The Blood Bank Management System exposes a delete.php script that processes record-removal requests. The script authenticates the caller but does not validate whether the caller owns the targeted record or holds an administrative role. As a result, any authenticated user can submit requests that delete arbitrary records.
The issue is a horizontal and vertical privilege escalation. Low-privilege users can affect records belonging to other users or to administrators. Because the application stores blood donor and inventory data, unauthorized deletions can corrupt operational data used for medical logistics.
The vulnerability requires network access to the web application and valid credentials. No user interaction is needed beyond submitting an HTTP request. Exploitation is straightforward and does not require evading authentication or bypassing additional controls.
Root Cause
The root cause is missing authorization checks in delete.php. The endpoint relies on session authentication alone and does not verify role or ownership of the resource referenced in the request parameters. This is a classic broken access control pattern tracked under [CWE-284].
Attack Vector
An attacker authenticates to the application using any valid account, including a self-registered user. The attacker then sends a crafted HTTP request to delete.php with parameters referencing records owned by other users or by administrative accounts. The server processes the deletion without verifying authorization. See the GitHub CVE Analysis and the GitHub Project Repository for technical details.
Detection Methods for CVE-2025-63525
Indicators of Compromise
- Unexpected HTTP requests to delete.php originating from non-administrative session cookies.
- Database records removed without a corresponding administrative audit entry.
- Multiple deletion requests from a single low-privilege account targeting different record IDs in sequence.
Detection Strategies
- Inspect web server access logs for POST or GET requests to delete.php and correlate the authenticated user with the affected record owner.
- Enable application-level audit logging for all delete operations and flag mismatches between actor role and resource ownership.
- Deploy a web application firewall rule that blocks requests to delete.php unless the session belongs to an administrative role.
Monitoring Recommendations
- Monitor for spikes in deletion activity tied to a single session identifier or IP address.
- Alert on database row count drops in donor and inventory tables outside of approved maintenance windows.
- Track authentication events for accounts that exhibit privilege-sensitive activity shortly after login.
How to Mitigate CVE-2025-63525
Immediate Actions Required
- Restrict access to delete.php at the web server or reverse proxy level so only administrative paths can invoke it.
- Disable self-registration on the application until access control is enforced server-side.
- Audit recent deletions and restore affected records from backups where required.
Patch Information
No official vendor patch is referenced in the NVD entry for CVE-2025-63525 at the time of publication. The upstream project is hosted at the GitHub Project Repository. Operators should monitor the repository for updates and apply server-side authorization checks that validate both role and resource ownership before processing deletions.
Workarounds
- Add a server-side role check at the top of delete.php that rejects requests from non-administrative sessions.
- Implement an ownership check that compares the session user ID to the record owner before executing the delete query.
- Place the application behind authenticated reverse proxy rules that restrict delete.php to trusted administrative IP ranges.
# Example Apache configuration restricting delete.php to admin network
<Location "/delete.php">
Require ip 10.0.0.0/24
