CVE-2025-7592 is a SQL Injection vulnerability identified in version 1.3 of the PHPGurukul Dairy Farm Shop Management System, specifically within the invoices.php file. The vulnerability arises from improper sanitization or validation of the 'del' parameter, which an attacker can manipulate to inject malicious SQL code. This flaw allows remote attackers to execute arbitrary SQL commands on the backend database without requiring authentication or user interaction. The vulnerability is classified as medium severity with a CVSS 4.0 base score of 5.3, reflecting its moderate impact and relatively straightforward exploitability. The attack vector is network-based (AV:N), with low attack complexity (AC:L), no privileges required (PR:L - low privileges), and no user interaction needed (UI:N). The impact on confidentiality, integrity, and availability is limited (VC:L, VI:L, VA:L), suggesting partial compromise potential rather than full system takeover. The vulnerability does not involve scope changes or security controls bypass (SC:N, SI:N, SA:N). Although no known exploits are currently active in the wild, the public disclosure of the exploit code increases the risk of exploitation. This vulnerability could allow attackers to extract sensitive data, modify or delete records, or disrupt normal database operations, potentially affecting business continuity and data integrity within organizations using this software.

For European organizations using PHPGurukul Dairy Farm Shop Management System 1.3, this vulnerability poses a tangible risk to the confidentiality and integrity of their business data, particularly financial and transactional records managed through the invoices.php module. Exploitation could lead to unauthorized data disclosure, manipulation of sales or inventory data, and disruption of invoicing processes, which are critical for operational and financial reporting. This could result in financial losses, regulatory non-compliance (especially under GDPR if personal data is involved), reputational damage, and operational downtime. Given the remote exploitability and lack of required user interaction, attackers can target vulnerable systems at scale, potentially impacting multiple organizations. The medium severity rating indicates that while the vulnerability is serious, it may require some level of access or conditions to fully exploit, limiting widespread impact but still necessitating prompt remediation.

To mitigate this vulnerability, organizations should immediately upgrade to a patched version of the PHPGurukul Dairy Farm Shop Management System once available. In the absence of an official patch, applying input validation and parameterized queries or prepared statements for the 'del' parameter in invoices.php is critical to prevent SQL injection. Employing Web Application Firewalls (WAFs) with rules to detect and block SQL injection attempts targeting this parameter can provide interim protection. Regularly auditing and monitoring database logs for suspicious queries related to the 'del' parameter can help detect exploitation attempts early. Additionally, restricting database user privileges to the minimum necessary can limit the potential damage from successful injection attacks. Organizations should also ensure that backups of critical data are current and tested to enable recovery in case of data corruption or loss.
