CVE-2025-2846 Overview
A critical SQL injection vulnerability has been identified in SourceCodester Online Eyewear Shop version 1.0. This vulnerability exists in the registration function of the file /oews/classes/Users.php?f=registration within the Registration component. The flaw allows remote attackers to inject malicious SQL commands through manipulation of the ID argument, potentially compromising database integrity, confidentiality, and availability. The exploit has been publicly disclosed, increasing the risk of active exploitation.
Critical Impact
Remote attackers can exploit this SQL injection vulnerability to bypass authentication, extract sensitive data, modify database records, or potentially execute arbitrary commands on the underlying database server.

Technical Details for CVE-2025-2846
Vulnerability Analysis
This vulnerability represents a classic SQL injection flaw categorized under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component). The registration function in the Online Eyewear Shop application fails to properly sanitize user-supplied input for the ID parameter before incorporating it into SQL queries. This allows attackers to inject arbitrary SQL statements that execute with the privileges of the database user configured for the application.
The vulnerability is remotely exploitable without authentication, making it particularly dangerous for internet-facing deployments. Successful exploitation could lead to unauthorized access to customer data, order information, payment details, and administrative credentials stored in the application's database.
Root Cause
The root cause of CVE-2025-2846 is improper input validation and lack of parameterized queries in the registration functionality. The Users.php file directly concatenates user-controlled input from the ID argument into SQL statements without adequate sanitization or use of prepared statements. This design flaw violates secure coding practices and enables injection attacks.
Attack Vector
The attack vector is network-based, requiring no authentication or user interaction. An attacker can craft malicious HTTP requests to the vulnerable endpoint /oews/classes/Users.php?f=registration with specially crafted SQL payloads in the ID parameter. The injection point allows manipulation of the query structure, enabling techniques such as UNION-based extraction, boolean-based blind injection, or time-based blind injection depending on the application's error handling and response behavior.
The vulnerability can be exploited by submitting crafted registration requests where the ID parameter contains SQL metacharacters and statements. For example, an attacker could inject payloads to extract database schema information, enumerate table contents, or modify existing records. Technical details are available in the GitHub CVE Documentation.
Detection Methods for CVE-2025-2846
Indicators of Compromise
- Unusual SQL error messages in application logs referencing the Users.php file or registration functionality
- Web server access logs showing requests to /oews/classes/Users.php?f=registration with SQL syntax in parameters
- Database query logs indicating UNION SELECT statements, information_schema queries, or time-delay functions
- Failed or anomalous registration attempts with non-standard characters in user input fields
Detection Strategies
- Deploy web application firewall (WAF) rules to detect and block common SQL injection patterns in HTTP requests
- Implement database activity monitoring to identify suspicious queries originating from the web application user
- Configure intrusion detection systems (IDS) with signatures for SQL injection attempts targeting PHP applications
- Enable detailed application logging for the registration endpoint to capture malformed input attempts
Monitoring Recommendations
- Monitor HTTP request parameters for SQL metacharacters including single quotes, semicolons, and comment sequences
- Track database connection anomalies and unusual query execution times that may indicate blind SQL injection attempts
- Establish baseline metrics for registration activity and alert on statistical deviations
- Review web application firewall logs for blocked requests matching SQL injection patterns
How to Mitigate CVE-2025-2846
Immediate Actions Required
- Restrict network access to the vulnerable application until patches or workarounds are applied
- Implement web application firewall rules to filter malicious SQL injection payloads
- Review database permissions and minimize privileges for the application database user
- Enable database query logging to detect potential exploitation attempts
- Consider taking the registration functionality offline temporarily if feasible
Patch Information
No official vendor patch information is currently available for this vulnerability. Organizations using SourceCodester Online Eyewear Shop 1.0 should monitor the SourceCodester website for security updates. Additional technical details can be found in the VulDB advisory.
Workarounds
- Implement input validation using parameterized queries or prepared statements in Users.php
- Deploy a web application firewall to filter SQL injection attempts at the network perimeter
- Restrict access to the registration endpoint via IP whitelisting or authentication requirements
- Apply virtual patching through WAF rules while awaiting an official fix
# Example WAF rule for ModSecurity to block SQL injection attempts
SecRule ARGS "@detectSQLi" "id:1001,phase:2,deny,status:403,log,msg:'SQL Injection Attempt Detected'"
# Restrict access to vulnerable endpoint via .htaccess
# <Files "Users.php">
# Order Deny,Allow
# Deny from all
# Allow from 192.168.1.0/24
# </Files>
