CVE-2025-7589: Dairy Farm Shop Management System SQLi Flaw

CVE-2025-7589 Overview

CVE-2025-7589 is a SQL injection vulnerability in PHPGurukul Dairy Farm Shop Management System version 1.3. The flaw resides in edit-company.php, where the companyname parameter is concatenated into a SQL query without proper sanitization. An authenticated remote attacker can manipulate this parameter to inject arbitrary SQL statements. The exploit has been disclosed publicly, increasing the likelihood of opportunistic attacks against exposed deployments. The vulnerability is categorized under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component).

Critical Impact
Authenticated attackers can inject SQL through the companyname parameter in edit-company.php, exposing or modifying backend database records.

Affected Products

Technical Details for CVE-2025-7589

Vulnerability Analysis

The vulnerability stems from unsafe handling of the companyname HTTP request parameter inside edit-company.php. The application incorporates user-supplied input directly into a SQL statement without prepared statements or input validation. This allows an attacker to break out of the intended SQL string context and append arbitrary clauses.

Because the attack requires only low-level authenticated access and can be initiated remotely, attackers who acquire any valid account credential can leverage it. The public disclosure of exploit details lowers the barrier for opportunistic exploitation against internet-exposed installations.

Root Cause

The root cause is the absence of parameterized queries in the company-edit workflow. User input flows from the HTTP request into the SQL query string through direct concatenation. PHP's mysqli or PDO prepared statement APIs are not used to bind the companyname value, leaving the query grammar attacker-controlled.

Attack Vector

An attacker authenticates to the application and submits a crafted POST or GET request to edit-company.php with a malicious companyname payload. Typical SQL injection techniques include union-based extraction, boolean-based blind injection, and time-based blind injection. Successful exploitation can disclose database content, alter records, or escalate access depending on the database user privileges.

No verified proof-of-concept code is published in NVD. See the GitHub Issue #135 and the VulDB entry #316288 for technical details on the disclosed exploit path.

Detection Methods for CVE-2025-7589

Indicators of Compromise

Unusual or malformed values in the companyname parameter of requests to edit-company.php, including quotes, SQL keywords (UNION, SELECT, SLEEP), or comment markers (--, #).
Web server access logs showing repeated POST requests to edit-company.php from a single source within a short interval.
Database error messages or stack traces returned to clients during interaction with the company-edit functionality.

Detection Strategies

Deploy Web Application Firewall (WAF) rules that inspect the companyname parameter for SQL metacharacters and known injection signatures.
Enable database query logging and alert on queries originating from edit-company.php that contain UNION, INFORMATION_SCHEMA, or time-delay functions.
Correlate authentication events with sudden bursts of requests to administrative endpoints such as edit-company.php.

Monitoring Recommendations

Monitor outbound database traffic for anomalous result-set sizes that may indicate data exfiltration.
Track failed and successful logins followed by immediate access to company management pages.
Review application error logs for SQL syntax errors tied to the edit-company workflow.

How to Mitigate CVE-2025-7589

Immediate Actions Required

Restrict network access to the Dairy Farm Shop Management System administrative interface using IP allowlists or VPN-only access.
Audit application accounts and disable any unused or shared credentials that could be abused to reach edit-company.php.
Review database logs for suspicious activity dating back to the application's deployment.

Patch Information

As of the last NVD update on 2026-04-29, no vendor advisory or official patch is listed in the references. Consult the PHP Gurukul website for updates and apply any released fixed version immediately. Until a patch is available, code-level remediation should replace string concatenation in edit-company.php with prepared statements using mysqli::prepare() or PDO with bound parameters.

Workarounds

Place a WAF in front of the application with signatures blocking SQL injection patterns in the companyname parameter.
Apply server-side input validation to reject non-alphanumeric characters in company name fields.
Limit the database account used by the application to least privilege, removing DROP, ALTER, and cross-database SELECT rights.
If the edit-company functionality is not required, disable or remove edit-company.php from the deployment.
