CVE-2025-7599: Dairy Farm Shop Management System SQLi Flaw

CVE-2025-7599 Overview

CVE-2025-7599 is a SQL injection vulnerability in PHPGurukul Dairy Farm Shop Management System version 1.3. The flaw resides in the /invoice.php script, where the del parameter is passed directly into a database query without sanitization. Remote attackers with low-privileged authenticated access can manipulate the del argument to inject arbitrary SQL statements. The exploit details have been publicly disclosed, increasing the likelihood of opportunistic scanning and abuse. This weakness maps to CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component.

Critical Impact
Authenticated remote attackers can inject SQL through the del parameter in /invoice.php, exposing invoice records and underlying database contents.

Technical Details for CVE-2025-7599

Vulnerability Analysis

The vulnerability affects the invoice management component of the Dairy Farm Shop Management System. The /invoice.php script accepts a del request parameter used to identify invoice records for deletion. The application concatenates this value into a SQL statement without parameterization or input validation. As a result, attackers can break out of the intended query context and append additional SQL clauses.

Exploitation requires network access to the web application and a low-privileged authenticated session. No user interaction is required beyond issuing a crafted HTTP request. Successful injection can be leveraged to read arbitrary tables, enumerate the database schema, and extract customer, invoice, or credential data stored by the application.

Root Cause

The root cause is improper neutralization of special elements passed through the del parameter [CWE-74]. The application trusts client-supplied input and interpolates it directly into a SQL query. Prepared statements, parameterized queries, and input allow-listing are absent from this code path.

Attack Vector

The attack vector is network-based. An authenticated attacker sends an HTTP request to /invoice.php with a manipulated del value containing SQL metacharacters. Depending on the backend response handling, both error-based and time-based blind SQL injection techniques are viable. Public disclosure through the GitHub Issue Tracker and VulDB #316298 documents the injection point and provides reproduction guidance.

The vulnerability manifests when the del parameter is appended to a DELETE or SELECT query. See the referenced advisories for technical details.

Detection Methods for CVE-2025-7599

Indicators of Compromise

HTTP requests to /invoice.php containing SQL metacharacters such as single quotes, UNION SELECT, SLEEP(, or comment sequences (--, #) in the del parameter.
Database error messages or abnormal response delays returned from /invoice.php requests.
Unexpected DELETE operations or bulk row removals in the invoice tables.
Web server access logs showing repeated del= values from a single source IP within a short timeframe.

Detection Strategies

Deploy web application firewall (WAF) rules that inspect the del parameter of /invoice.php for SQL syntax patterns.
Enable database query logging and alert on multi-statement queries or UNION-based reads originating from the invoice module.
Correlate authentication logs with /invoice.php request bursts to identify credential-backed injection attempts.

Monitoring Recommendations

Aggregate web server, PHP, and MySQL logs into a central platform for query and parameter analysis.
Baseline normal invoice deletion volume and alert on statistical deviations.
Retain HTTP request bodies and query strings for forensic review of suspected injection activity.

How to Mitigate CVE-2025-7599

Immediate Actions Required

Restrict access to /invoice.php to trusted administrative IP ranges until a vendor fix is applied.
Rotate credentials for any accounts that authenticate to the Dairy Farm Shop Management System.
Review database audit logs for unauthorized reads, writes, or deletions in invoice-related tables.
Apply WAF signatures blocking SQL injection payloads targeting the del parameter.

Patch Information

No vendor advisory or patch has been published in the referenced sources at the time of NVD update on 2026-06-17. Monitor the PHPGurukul website and the GitHub Issue Tracker for remediation updates. Until an official fix is released, treat the application as vulnerable and apply compensating controls.

Workarounds

Modify /invoice.php to use parameterized queries or PHP Data Objects (PDO) prepared statements for the del parameter.
Enforce server-side type checking to accept only numeric invoice identifiers in the del argument.
Apply the principle of least privilege to the database account used by the application, removing rights that are not required for normal operation.
Disable or remove the invoice deletion endpoint if it is not actively required by business operations.
