CVE-2026-82614: Online Medicine Delivery System SQL Injection

CVE-2026-82614 Overview

CVE-2026-82614 is a SQL injection vulnerability in itsourcecode Online Medicine Delivery System 1.0. The flaw affects the loadResultList function in /index.php?q=product, part of the Product Category Filter Interface. Attackers can manipulate the Category argument to inject arbitrary SQL statements. The vulnerability is remotely exploitable without authentication or user interaction. A public exploit has been released, increasing the risk of opportunistic attacks against exposed installations.

Critical Impact
Unauthenticated remote attackers can inject SQL into the Product Category Filter, allowing extraction or modification of backend database records containing customer and medicine order data.

Affected Products

itsourcecode Online Medicine Delivery System 1.0
Component: Product Category Filter Interface (/index.php?q=product)

Technical Details for CVE-2026-82614

Vulnerability Analysis

The vulnerability resides in the loadResultList function invoked when a client requests /index.php?q=product with a Category parameter. The application concatenates the attacker-controlled Category value directly into a SQL query without parameterization or sanitization. This aligns with [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component). A remote, unauthenticated attacker can submit crafted Category values that alter the query structure and execute arbitrary SQL against the backend database.

Successful exploitation can disclose product catalogs, customer records, order history, and administrative credential hashes stored by the application. Depending on database privileges, the attacker may also modify records or leverage database features to read local files. A public proof-of-concept is available through the referenced GitHub SQL Injection Vulnerability writeup and VulDB CVE-2026-82614 entry.

Root Cause

The root cause is unsafe query construction inside loadResultList. The Category argument received from the HTTP request is embedded directly into a SQL statement without prepared statements, parameter binding, or input validation. PHP applications built on legacy mysql_query or unparameterized mysqli_query calls are particularly prone to this pattern.

Attack Vector

Exploitation requires only network access to the web application. The attacker issues an HTTP GET request to /index.php?q=product and supplies a malicious Category value containing SQL metacharacters such as single quotes, UNION SELECT clauses, or boolean-based inference payloads. No credentials, cookies, or user interaction are required.

See the GitHub SQL Injection Vulnerability writeup for the published payloads.

Detection Methods for CVE-2026-82614

Indicators of Compromise

HTTP requests to /index.php?q=product containing SQL metacharacters in the Category parameter such as ', --, UNION, SELECT, SLEEP(, or INFORMATION_SCHEMA.
Web server access logs showing unusually long or URL-encoded Category values from a single source IP address.
Database error messages surfaced in HTTP responses referencing MySQL syntax errors or malformed SQL fragments.
Unexpected database sessions executing queries against the users, orders, or products tables outside normal application patterns.

Detection Strategies

Deploy web application firewall (WAF) rules that inspect the Category query parameter for SQL injection signatures on /index.php?q=product.
Enable database query logging and alert on UNION SELECT or boolean-based payloads originating from the web application account.
Correlate web access logs with database logs to identify time-based SQL injection attempts producing delayed responses.

Monitoring Recommendations

Baseline normal Category parameter values and alert on entries containing whitespace, quotes, or SQL keywords.
Monitor for spikes in HTTP 500 responses from /index.php?q=product, which often indicate injection probing.
Track outbound connections from the database server that may indicate post-exploitation data exfiltration.

How to Mitigate CVE-2026-82614

Immediate Actions Required

Restrict public access to the Online Medicine Delivery System until a patch is available, or place it behind an authenticated reverse proxy.
Deploy WAF rules that block SQL injection patterns targeting the Category parameter on /index.php?q=product.
Audit the application database account and revoke unnecessary privileges such as FILE, CREATE, and DROP.
Review web and database logs for prior exploitation attempts using the indicators listed above.

Patch Information

No vendor patch is referenced in the NVD entry at the time of publication. Administrators should monitor the vendor site at IT Source Code Blog and the VulDB CVE-2026-82614 entry for updates. Where source code is available, remediation requires replacing string concatenation in loadResultList with parameterized queries using PDO prepared statements or mysqli with bound parameters.

Workarounds

Add server-side allowlist validation for the Category parameter, permitting only known category identifiers or numeric values.
Cast the Category argument to an integer before it reaches the SQL layer if the schema uses numeric category IDs.
Enable strict SQL mode on the MySQL server and configure the application to suppress verbose database errors in HTTP responses.
Isolate the application in a segmented network zone to limit lateral movement if the database is compromised.
