CVE-2025-12293: Janobe Point Of Sales SQLi Vulnerability

CVE-2025-12293 Overview

A SQL injection vulnerability has been identified in SourceCodester Point of Sales version 1.0. This vulnerability affects the /category.php file, where improper handling of the Category parameter allows attackers to inject malicious SQL statements. The vulnerability can be exploited remotely without authentication, potentially enabling unauthorized access to sensitive database information, data manipulation, or complete database compromise.

Critical Impact

Remote attackers can exploit this SQL injection flaw to extract sensitive customer and transaction data, modify database records, or potentially gain further access to backend systems through database-level privileges.

Affected Products

• Janobe Point of Sales 1.0
• SourceCodester Point of Sales implementations using vulnerable /category.php endpoint

Discovery Timeline

Technical Details for CVE-2025-12293

Vulnerability Analysis

This SQL injection vulnerability exists in the /category.php file of the SourceCodester Point of Sales application. The Category parameter is directly concatenated into SQL queries without proper sanitization or parameterized query implementation. This classic injection pattern allows attackers to manipulate database queries by inserting malicious SQL syntax through user-controllable input.

The vulnerability is network-exploitable, meaning attackers can target vulnerable installations remotely without requiring any prior authentication or user interaction. This significantly increases the attack surface and risk exposure for organizations running affected versions of this point-of-sale software.

Root Cause

The root cause stems from improper input validation and the absence of parameterized queries (prepared statements) in the application's database interaction layer. The Category parameter value is directly incorporated into SQL statements, creating a direct injection point. This violates fundamental secure coding practices outlined in CWE-89 (Improper Neutralization of Special Elements used in an SQL Command) and CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component).

Attack Vector

The attack is executed remotely over the network by sending crafted HTTP requests to the /category.php endpoint. An attacker manipulates the Category parameter to include SQL metacharacters and malicious query fragments. Successful exploitation can result in:

• Extraction of sensitive data including customer information, transaction records, and credentials
• Modification or deletion of database records
• Bypassing authentication mechanisms
• Potential lateral movement if database credentials provide access to other systems

The vulnerability requires no authentication and no user interaction, making it trivially exploitable by remote attackers. The exploit is publicly referenced in security databases, increasing the likelihood of opportunistic attacks against exposed systems.

Detection Methods for CVE-2025-12293

Indicators of Compromise

• Unusual or malformed requests to /category.php containing SQL syntax such as single quotes, UNION, SELECT, OR 1=1, or comment sequences (--, /*)
• Database error messages appearing in application logs or HTTP responses indicating malformed queries
• Unexpected database query patterns or unusual data access in database audit logs
• Evidence of data exfiltration or bulk data queries in database activity monitoring

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the Category parameter
• Implement application-layer monitoring to identify requests containing common SQL injection payloads
• Enable database query logging and alerting on suspicious statement patterns
• Configure intrusion detection systems (IDS) with signatures for SQL injection attacks

Monitoring Recommendations

• Monitor HTTP access logs for requests to /category.php with encoded or suspicious parameter values
• Enable database audit logging to track unusual query patterns and unauthorized data access
• Implement real-time alerting for application errors related to database query failures
• Review web server logs for repeated probing attempts against the vulnerable endpoint

How to Mitigate CVE-2025-12293

Immediate Actions Required

• Restrict network access to the Point of Sales application to trusted networks only
• Implement Web Application Firewall (WAF) rules to filter SQL injection attempts
• Consider disabling or restricting access to /category.php if not critical to operations
• Review database user permissions and apply principle of least privilege
• Back up all data immediately in case of compromise

Patch Information

As of the last NVD update on 2025-11-03, no official vendor patch has been documented for this vulnerability. Organizations should monitor the SourceCodester Resource Hub and vendor communications for security updates. Additional technical details are available through the VulDB Vulnerability Report and the GitHub Issue Discussion.

Workarounds

• Implement input validation to sanitize the Category parameter and reject values containing SQL metacharacters
• Modify the application code to use parameterized queries (prepared statements) for all database interactions
• Deploy a reverse proxy or WAF with SQL injection protection enabled in front of the application
• Isolate the database server and restrict direct network access from untrusted zones
• Consider migrating to an alternative point-of-sale solution with better security practices until a patch is available
