CVE-2025-3352 Overview
A SQL injection vulnerability has been identified in PHPGurukul Old Age Home Management System version 1.0. This vulnerability exists in the /admin/edit-scdetails.php file where the contnum parameter is improperly handled, allowing attackers to inject malicious SQL queries. The vulnerability can be exploited remotely without authentication, potentially leading to unauthorized database access, data manipulation, or complete system compromise.
Critical Impact
Remote attackers can exploit this SQL injection vulnerability to read, modify, or delete sensitive database contents including personal information of elderly residents and administrative credentials.

Technical Details for CVE-2025-3352
Vulnerability Analysis
This SQL injection vulnerability occurs due to insufficient input validation and sanitization in the /admin/edit-scdetails.php administrative endpoint. When processing requests containing the contnum parameter, the application directly incorporates user-supplied input into SQL queries without proper parameterization or escaping. This allows attackers to craft malicious input that alters the structure of the intended SQL query, enabling unauthorized database operations.
The vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), which encompasses injection flaws where attacker-controlled data is not properly sanitized before being processed by an interpreter.
Root Cause
The root cause of this vulnerability is the direct concatenation of user-supplied input (specifically the contnum parameter) into SQL statements without using prepared statements, parameterized queries, or adequate input sanitization. PHP applications using legacy database interaction patterns that concatenate variables directly into query strings are particularly susceptible to this class of vulnerability.
Attack Vector
The attack can be launched remotely over the network against the administrative panel of the Old Age Home Management System. An attacker can manipulate the contnum parameter in requests to /admin/edit-scdetails.php by injecting SQL metacharacters and malicious query fragments. This could enable data extraction through UNION-based injection, authentication bypass, or even command execution if the database is configured with elevated privileges.
The vulnerability is exploited by sending crafted HTTP requests to the vulnerable endpoint with malicious SQL code embedded in the contnum parameter. For example, an attacker might append SQL operators and subqueries to extract sensitive information from other database tables or bypass authentication controls. Technical details regarding the exploitation technique have been publicly disclosed. See the GitHub Issue Discussion and VulDB entry for additional technical information.
Detection Methods for CVE-2025-3352
Indicators of Compromise
- Unusual or malformed requests to /admin/edit-scdetails.php containing SQL syntax characters such as single quotes, semicolons, or UNION keywords in the contnum parameter
- Database error messages appearing in web server logs or application responses indicating SQL syntax errors
- Unexpected database queries or access patterns in database audit logs
Detection Strategies
- Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns in HTTP request parameters
- Enable detailed logging on the web server and database to capture suspicious query activity and failed authentication attempts
- Deploy intrusion detection systems (IDS) with signatures for SQL injection attack patterns targeting PHP applications
Monitoring Recommendations
- Monitor web server access logs for repeated requests to /admin/edit-scdetails.php with unusual parameter values
- Set up alerts for database query anomalies or errors that may indicate injection attempts
- Review application logs regularly for signs of unauthorized data access or modification
How to Mitigate CVE-2025-3352
Immediate Actions Required
- Restrict access to the administrative panel (/admin/) to trusted IP addresses only using network-level access controls or web server configuration
- Implement input validation and sanitization for all user-supplied parameters, particularly contnum
- Consider taking the application offline or disabling the affected functionality until a patch is available
Patch Information
No official patch information has been released by PHPGurukul at the time of this analysis. Organizations should monitor the PHPGurukul website for security updates. It is strongly recommended to implement manual code fixes using prepared statements with parameterized queries to address this SQL injection vulnerability.
Workarounds
- Use a Web Application Firewall (WAF) to filter and block SQL injection attempts targeting the vulnerable endpoint
- Implement network segmentation to limit database access from the web application server
- Apply the principle of least privilege to database accounts used by the application to minimize potential damage from successful exploitation
