CVE-2025-8931: Medical Store Management System SQL Injection

CVE-2025-8931 Overview

CVE-2025-8931 is a SQL injection vulnerability in code-projects Medical Store Management System 1.0. The flaw resides in the ChangePassword.java file, where the newPassTxt argument is passed to a database query without proper sanitization. Remote attackers with low privileges can manipulate this parameter to inject arbitrary SQL statements. The vulnerability has been publicly disclosed, and proof-of-concept details are available through third-party vulnerability databases. The issue is tracked under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component).

Critical Impact

Authenticated remote attackers can inject SQL commands through the password change function, potentially compromising stored credentials and patient inventory data.

Technical Details for CVE-2025-8931

Vulnerability Analysis

The vulnerability is a SQL injection flaw within the password change workflow of the Medical Store Management System. The ChangePassword.java component accepts a user-supplied newPassTxt value and concatenates it into a SQL statement without parameterized queries or input sanitization. An authenticated attacker with low-level privileges can craft a malicious payload that alters the intended SQL logic. Exploitation can be performed remotely over the network and does not require user interaction.

Successful exploitation can lead to unauthorized read or modification of database records. In the context of a medical store management application, affected data may include user credentials, inventory records, and customer information. Because the application is a Java-based system handling sensitive healthcare-adjacent data, exploitation has direct privacy and integrity implications.

Root Cause

The root cause is improper neutralization of input passed to a SQL query [CWE-74]. The newPassTxt argument is directly embedded in a query string rather than bound through a PreparedStatement. This pattern allows special SQL characters such as single quotes, semicolons, and comment delimiters to break out of the intended literal context and modify query structure.

Attack Vector

An attacker authenticates to the application with low-privilege credentials, then submits a crafted value to the password change function. The malicious newPassTxt payload manipulates the underlying SQL statement to extract, modify, or delete database contents. The attack requires network access to the application but no user interaction beyond the attacker's own session.

No verified public proof-of-concept code is available in the referenced sources. Technical details are documented at VulDB #319890 and the Yuque Vulnerability Details page.

Detection Methods for CVE-2025-8931

Indicators of Compromise

• Unexpected SQL syntax characters (', --, ;, UNION, OR 1=1) in HTTP POST bodies submitted to the password change endpoint.
• Database error messages or stack traces returned in application responses following password change requests.
• Anomalous read or write activity against user authentication tables shortly after a password change request.

Detection Strategies

• Inspect application and web server logs for requests targeting the ChangePassword handler containing SQL metacharacters in the newPassTxt parameter.
• Enable database query logging and alert on queries originating from the password change function that deviate from the expected parameterized form.
• Deploy a web application firewall (WAF) with SQL injection signatures tuned for Java application endpoints.

Monitoring Recommendations

• Monitor authentication and account management endpoints for high request volume or repeated failures, which may indicate injection probing.
• Correlate password change events with subsequent privileged access or unusual data export activity.
• Track outbound database connections from the application server for unexpected query patterns.

How to Mitigate CVE-2025-8931

Immediate Actions Required

• Restrict network access to the Medical Store Management System to trusted internal networks only.
• Audit all user accounts and rotate credentials for any account that may have authenticated during the exposure window.
• Place the affected ChangePassword endpoint behind a WAF rule that blocks SQL metacharacters in the newPassTxt parameter.

Patch Information

No vendor patch has been published in the referenced advisories. code-projects has not released a fixed version of Medical Store Management System 1.0 as of the last NVD update. Organizations should review the Code Projects Resources site for any future updates and consider migrating to a maintained alternative if no patch becomes available.

Workarounds

• Modify the ChangePassword.java source to use a PreparedStatement with bound parameters instead of string concatenation for the newPassTxt value.
• Apply server-side input validation that rejects non-printable characters, SQL keywords, and length anomalies before any database interaction.
• Run the application database account with least-privilege permissions, removing DROP, ALTER, and administrative rights to limit the impact of successful injection.
• If source modification is not feasible, isolate the application on a segmented network and disable external access until a fix is available.
