CVE-2025-11319 Overview
CVE-2025-11319 is a SQL injection vulnerability in the nahiduddinahammed Hospital-Management-System-Website project. The flaw resides in /delete.php and is triggered through manipulation of the ai argument. An authenticated remote attacker with low privileges can inject arbitrary SQL statements into the underlying database query. The project follows a rolling release model, so no fixed version identifiers are available. A public exploit report has been released, and the vendor did not respond to disclosure attempts. The weakness is classified under CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component.
Critical Impact
Remote attackers with low-privilege access can inject SQL through the ai parameter of /delete.php, potentially reading, modifying, or deleting patient and hospital records.

Technical Details for CVE-2025-11319
Vulnerability Analysis
The vulnerability exists in the /delete.php script of the Hospital-Management-System-Website. The script consumes the ai request parameter and concatenates it into a SQL statement without proper sanitization or parameterization. An attacker can supply crafted input that alters the intended query logic. Because the project uses a rolling release model, no discrete patched version is available for defenders to track. A public writeup describing the flaw has been published on GitHub, increasing the likelihood of opportunistic exploitation against exposed instances.
Root Cause
The root cause is improper neutralization of user-controlled input passed through the ai parameter before it is included in a database query. The application does not enforce prepared statements or escape special characters. This maps to [CWE-74], the parent weakness class covering injection flaws where downstream components misinterpret attacker-supplied data.
Attack Vector
Exploitation occurs over the network against the vulnerable web endpoint. An attacker sends a crafted HTTP request to /delete.php with a malicious ai parameter value containing SQL syntax. Successful injection can enumerate database schema, extract records, or modify hospital data such as patient records, appointments, and staff credentials. The attack requires low privileges but no user interaction.
See the GitHub SQL Injection Report and VulDB entry #327200 for the disclosed technical details.
Detection Methods for CVE-2025-11319
Indicators of Compromise
- HTTP requests to /delete.php containing SQL metacharacters in the ai parameter such as single quotes, UNION, SELECT, --, or /*
- Unexpected database errors or stack traces returned to clients from the delete endpoint
- Anomalous read or write operations against hospital database tables originating from the web application user
Detection Strategies
- Deploy web application firewall (WAF) rules that flag SQL injection payloads targeting the ai query string or POST parameter
- Enable database query logging and alert on statements referencing multiple tables initiated by /delete.php
- Correlate authentication events with subsequent access to /delete.php to identify abuse from low-privilege accounts
Monitoring Recommendations
- Monitor web server access logs for repeated requests to /delete.php with encoded or obfuscated parameter values
- Track outbound traffic from the database host for signs of data exfiltration following suspicious query activity
- Baseline normal record deletion rates and alert on volume spikes indicating automated exploitation
How to Mitigate CVE-2025-11319
Immediate Actions Required
- Restrict network access to the Hospital-Management-System-Website until code-level fixes are applied
- Audit /delete.php and surrounding scripts for direct concatenation of request parameters into SQL statements
- Rotate database credentials and review recent activity in hospital data tables for unauthorized changes
Patch Information
No vendor patch is available. The project maintainer did not respond to disclosure attempts, and the rolling release model does not provide fixed version identifiers. Operators should refer to the VulDB advisory #327200 and apply source-level fixes by replacing vulnerable SQL construction with prepared statements using parameter binding.
Workarounds
- Rewrite queries in /delete.php to use parameterized statements (PDO::prepare with bound parameters or mysqli prepared statements)
- Add server-side input validation to reject non-numeric values for the ai parameter if it represents a record identifier
- Deploy a WAF ruleset such as the OWASP ModSecurity Core Rule Set to block common SQL injection payloads at the perimeter
- Enforce least privilege on the database account used by the application so it cannot drop tables or read unrelated schemas
