CVE-2024-9976: Pharmacy Management System SQLi Vulnerability

CVE-2024-9976 Overview

CVE-2024-9976 is a SQL injection vulnerability affecting code-projects Pharmacy Management System 1.0. The flaw resides in the /php/manage_customer.php endpoint when invoked with the action=search parameter. Attackers can manipulate the text argument to inject arbitrary SQL statements into the backend database query. The vulnerability is remotely exploitable over the network and requires low-level privileges. Public disclosure of the exploit details has occurred, increasing the risk of opportunistic attacks against exposed installations. The weakness is classified under CWE-89, Improper Neutralization of Special Elements used in an SQL Command.

Critical Impact

Remote attackers with low privileges can execute arbitrary SQL queries against the application database, potentially exposing customer records, credentials, and prescription data.

Technical Details for CVE-2024-9976

Vulnerability Analysis

The vulnerability is a SQL injection flaw in the customer search functionality of the Pharmacy Management System. When the application processes requests to /php/manage_customer.php?action=search, it incorporates the text parameter directly into a SQL query without proper sanitization or parameterization. Attackers supply crafted input through the text argument to alter query semantics. The exploit has been publicly disclosed, lowering the barrier to attack. Exposed customer data within the pharmacy database becomes accessible to unauthorized parties.

Root Cause

The root cause is improper neutralization of special characters in user-supplied input passed to a SQL statement [CWE-89]. The text parameter received via HTTP request flows into the database query unfiltered. The application does not use prepared statements or parameterized queries. This allows attacker-controlled SQL syntax to execute within the database context.

Attack Vector

An attacker sends an HTTP request to the search endpoint with a malicious payload in the text parameter. Because the endpoint is reachable over the network, exploitation does not require local access. The attacker requires only low-level authenticated access to the application. Successful exploitation enables data extraction through UNION-based, boolean-based, or time-based injection techniques.

No verified proof-of-concept code is published in this advisory. Refer to the GitHub Gist Snippet and VulDB #280341 for technical disclosure details.

Detection Methods for CVE-2024-9976

Indicators of Compromise

• HTTP requests to /php/manage_customer.php?action=search containing SQL metacharacters such as ', --, UNION, SLEEP(, or OR 1=1 in the text parameter
• Unusual database query patterns or slow query log entries originating from the customer search workflow
• Unexpected outbound database connections or large result sets returned to the web application

Detection Strategies

• Deploy web application firewall rules that inspect the text query string parameter for SQL injection signatures
• Enable verbose database query logging and correlate anomalous query structures with web access logs
• Monitor for repeated 500-series responses from manage_customer.php that may indicate injection probing

Monitoring Recommendations

• Alert on HTTP requests where the text parameter length or character composition deviates from baseline customer search behavior
• Track authenticated user accounts generating high volumes of search requests against the pharmacy application
• Forward web server and database logs to a centralized logging platform for correlation and retention

How to Mitigate CVE-2024-9976

Immediate Actions Required

• Restrict network access to the Pharmacy Management System to trusted internal networks or VPN clients
• Disable or restrict the /php/manage_customer.php endpoint until a patched build is available
• Audit existing application and database logs for indicators of prior exploitation against the search endpoint
• Rotate database credentials used by the web application if compromise is suspected

Patch Information

No official vendor patch is referenced in the NVD entry for CVE-2024-9976. Administrators should monitor the Code Projects Resource Hub for security updates and consult the VulDB CTI ID #280341 record for additional remediation guidance.

Workarounds

• Place the application behind a web application firewall configured to block SQL injection patterns targeting the text parameter
• Modify the affected PHP source to use parameterized queries or prepared statements with PDO or mysqli bindings
• Apply input validation to enforce expected character sets and maximum length on the text search field
• Restrict the database account used by the application to least-privilege read access on required tables only
