CVE-2026-82613: Medicine Delivery System SQL Injection Flaw

CVE-2026-82613 Overview

CVE-2026-82613 is a SQL injection vulnerability in itsourcecode Online Medicine Delivery System 1.0. The flaw resides in the loadResultList function of /index.php?q=product, part of the Product Search Interface. Attackers can manipulate the Search parameter to inject arbitrary SQL statements into backend database queries. The vulnerability is remotely exploitable without authentication or user interaction, and a public exploit is available. The weakness is categorized under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component).

Critical Impact
Unauthenticated remote attackers can execute arbitrary SQL queries against the application database, resulting in disclosure or modification of stored records.

Technical Details for CVE-2026-82613

Vulnerability Analysis

The vulnerability affects the product search feature of the Online Medicine Delivery System. When a user submits a search query, the loadResultList function receives the Search parameter and incorporates it directly into a SQL LIKE clause without sanitization or parameterization. The public advisory identifies this as a SQL injection in a LIKE construct, meaning the attacker-controlled string is concatenated into a query similar to ... WHERE product_name LIKE '%<input>%'. An attacker can break out of the string literal and append arbitrary SQL syntax, including UNION SELECT payloads to extract rows from other tables.

Root Cause

The root cause is improper neutralization of special elements passed to a downstream SQL interpreter [CWE-74]. The application concatenates the Search request parameter into a dynamic SQL statement rather than using prepared statements with bound parameters. Standard PHP database APIs such as PDO or mysqli prepared statements would prevent this class of flaw, but the code path relies on direct string interpolation.

Attack Vector

The attack is initiated over the network against the public product search endpoint. No authentication or user interaction is required. An attacker sends a crafted HTTP request to /index.php?q=product with a malicious Search value that terminates the LIKE string and appends additional SQL. Because the exploit is publicly documented in a GitHub proof-of-concept, opportunistic scanning against exposed instances is likely. Details are also tracked in VulDB CVE-2026-82613.

No verified exploit code is republished here. Refer to the linked advisory for the technical payload structure.

Detection Methods for CVE-2026-82613

Indicators of Compromise

Web server access logs containing requests to /index.php?q=product with SQL keywords such as UNION, SELECT, SLEEP, --, or %27 in the Search parameter.
Unusually long or URL-encoded values in the Search query string parameter.
Database error messages returned to clients or written to application logs indicating malformed LIKE clauses.
Anomalous spikes in query duration originating from the product search endpoint, consistent with time-based blind SQL injection.

Detection Strategies

Deploy web application firewall rules that inspect the Search parameter for SQL metacharacters and common injection payloads.
Enable database query logging and alert on queries containing concatenated user input reaching the products table.
Correlate web access logs with database audit logs to identify successful injection attempts that returned non-standard result sets.

Monitoring Recommendations

Monitor HTTP request patterns against /index.php?q=product for automated scanner signatures (sqlmap, Ghauri).
Track outbound data volume from the application database server to detect bulk exfiltration following successful injection.
Review authentication and administrative account activity for anomalies after any suspected injection event.

How to Mitigate CVE-2026-82613

Immediate Actions Required

Restrict public exposure of the Online Medicine Delivery System until a fix is applied, ideally placing it behind VPN or IP allow-listing.
Deploy WAF signatures blocking SQL injection patterns targeting the Search parameter on /index.php?q=product.
Audit the application database for unauthorized reads, new administrative accounts, or modified product records.
Rotate database credentials and any secrets that may have been exposed through the vulnerable query path.

Patch Information

No official vendor patch has been published at the time of NVD disclosure. Administrators should track the IT Source Code project page for updates. In the interim, apply source-code remediation by rewriting loadResultList to use parameterized queries with bound parameters, and escape any wildcard characters (%, _) before insertion into the LIKE clause.

Workarounds

Implement server-side input validation restricting the Search parameter to an allow-list of alphanumeric characters and spaces.
Enforce least-privilege database accounts so the web application user cannot read sensitive tables or execute administrative statements.
Disable verbose SQL error messages returned to clients to slow attacker reconnaissance and blind injection techniques.
Deploy a reverse proxy or WAF with virtual patching rules until source-level fixes are deployed.
