CVE-2026-82615: Online Medicine Delivery System SQLi Flaw

CVE-2026-82615 Overview

CVE-2026-82615 is a SQL injection vulnerability in itsourcecode Online Medicine Delivery System 1.0. The flaw resides in the Customer::find_phone function within /passwordrecover.php, part of the Password Recovery Interface. Attackers can manipulate the phonenumber argument to inject arbitrary SQL statements without authentication. The issue is classified under CWE-74: Improper Neutralization of Special Elements in Output. Public disclosure of the exploit technique has occurred, increasing the likelihood of opportunistic attacks against exposed deployments.

Critical Impact
Unauthenticated remote attackers can inject SQL into the password recovery workflow, potentially exposing customer credentials and enabling account takeover.

Technical Details for CVE-2026-82615

Vulnerability Analysis

The vulnerability exists in the password recovery flow of the Online Medicine Delivery System. When a user submits a phone number to recover an account, the Customer::find_phone method in /passwordrecover.php incorporates the phonenumber parameter directly into a SQL query. The absence of parameterized queries or input sanitization allows an attacker to break out of the intended query context. Successful exploitation can disclose stored user data, including hashed credentials and personal information. Because the password recovery endpoint is publicly reachable, no prior authentication is required to trigger the injection.

Root Cause

The root cause is improper neutralization of special elements in the phonenumber input before it is concatenated into a SQL statement [CWE-74]. The application trusts client-supplied data and passes it to the database driver without prepared statements or escaping. This design flaw allows the injected payload to alter query logic and read arbitrary rows from backend tables.

Attack Vector

Exploitation occurs over the network against the password recovery endpoint. An attacker sends a crafted HTTP request containing SQL metacharacters in the phonenumber parameter. The injected payload can employ UNION-based or boolean-based techniques to extract data from other tables. Public technical details are documented in the GitHub SQL Injection Guide and in the VulDB CVE-2026-82615 entry.

No verified proof-of-concept code is reproduced here. Refer to the published references for exploitation specifics.

Detection Methods for CVE-2026-82615

Indicators of Compromise

HTTP POST or GET requests to /passwordrecover.php containing SQL metacharacters such as ', --, UNION, or SLEEP( in the phonenumber parameter.
Unusual response time variations on the password recovery endpoint indicating time-based blind SQL injection.
Web server logs showing repeated recovery requests from a single source with varied phonenumber payloads.
Database error messages returned to clients referencing SQL syntax or table structures.

Detection Strategies

Deploy web application firewall (WAF) rules that flag SQL keywords and tautologies in parameters submitted to /passwordrecover.php.
Enable database query logging and alert on queries originating from the password recovery module that contain unexpected clauses.
Correlate authentication failures with recovery requests to spot enumeration or extraction attempts.

Monitoring Recommendations

Monitor outbound data volumes from the database host tied to the password recovery workflow.
Track HTTP 500 responses from /passwordrecover.php as they often accompany failed injection attempts.
Review access logs for high-frequency requests to the recovery endpoint from single IP addresses or subnets.

How to Mitigate CVE-2026-82615

Immediate Actions Required

Restrict access to /passwordrecover.php at the network or WAF layer until a fix is available.
Audit the users and customers tables for signs of unauthorized reads or modifications.
Force password resets for all accounts if evidence of credential extraction exists.
Rate-limit requests to the password recovery endpoint to slow brute-force injection attempts.

Patch Information

No vendor patch has been referenced in the published advisory. Consult the IT Source Code Homepage and the VulDB Vulnerability #397116 entry for updates. Because this project is distributed as source code, operators should apply code-level fixes: replace string concatenation in Customer::find_phone with parameterized queries using PDO prepared statements or mysqli_prepare with bound parameters.

Workarounds

Rewrite the affected query in Customer::find_phone to use prepared statements with bound phonenumber parameters.
Add server-side input validation that rejects non-numeric characters in the phonenumber field before it reaches the database layer.
Configure the database account used by the application with least-privilege permissions to limit the impact of successful injection.
Temporarily disable the password recovery feature if code changes cannot be applied immediately.
