A high-severity SQL Injection vulnerability has been identified in the phpgurukul Complaint Management System 2. This flaw allows an attacker to manipulate the application's database, potentially leading to unauthorized access, theft, or modification of sensitive complaint data and user information.

The application fails to properly sanitize user-supplied input before incorporating it into SQL queries. An unauthenticated attacker can inject malicious SQL commands into input fields (such as login forms or URL parameters). This allows the attacker to bypass security controls and execute arbitrary commands on the backend database.

This is a High severity vulnerability with a CVSS score of 7.5. Successful exploitation could lead to a significant data breach, including the exposure of sensitive customer complaints, personal identifiable information (PII), and user credentials. The potential consequences include unauthorized data access, data modification, or complete deletion of database records, leading to severe reputational damage, regulatory penalties, and loss of customer trust.

Immediate Action: Apply vendor patches immediately to address the root cause of the vulnerability. Review existing database user accounts and access controls to ensure the application is operating with the principle of least privilege. Enable and configure detailed database query logging to capture all executed commands for future auditing and incident response.

Proactive Monitoring: Monitor web application firewall (WAF), web server, and database logs for suspicious patterns, such as queries containing SQL keywords like UNION, SELECT, --, or ' OR '1'='1'. Network monitoring should be in place to detect any unusual or large data transfers from the database server.

Compensating Controls: If immediate patching is not feasible, deploy a Web Application Firewall (WAF) with a strict ruleset designed to block SQL injection attacks. Implement stringent input validation on the web server as an interim measure. Restrict network access to the database server to only the application server.

Public Exploit Available: false

Immediate patching of CVE-2025-57147 is strongly recommended due to its High severity rating and the potential for a complete compromise of sensitive data. Although this vulnerability is not currently on the CISA KEV list, the ease of exploitation and high impact necessitate urgent action. Organizations must prioritize the deployment of vendor patches and implement the recommended monitoring and compensating controls to mitigate the significant risk of a data breach.
