CVE-2025-11039 Overview
A SQL injection vulnerability has been identified in Campcodes Computer Sales and Inventory System version 1.0. The vulnerability exists in an unknown functionality of the file /pages/us_edit1.php, where improper handling of the ID parameter allows attackers to inject malicious SQL queries. This vulnerability can be exploited remotely without authentication, making it a significant security concern for organizations using this inventory management software.
Critical Impact
Remote attackers can exploit this SQL injection vulnerability to extract sensitive database information, modify or delete records, and potentially compromise the entire underlying database system. The exploit has been publicly disclosed, increasing the risk of widespread exploitation.

Technical Details for CVE-2025-11039
Vulnerability Analysis
This SQL injection vulnerability affects the /pages/us_edit1.php file within the Campcodes Computer Sales and Inventory System. The application fails to properly sanitize user-supplied input in the ID parameter before incorporating it into SQL queries. This allows attackers to inject arbitrary SQL commands that will be executed by the database server.
The vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), commonly referred to as injection vulnerabilities. SQL injection attacks can lead to unauthorized data access, data manipulation, and in some cases, complete system compromise.
Since the vulnerability is network-accessible and requires no authentication or user interaction, it presents a significant attack surface for malicious actors targeting systems running this inventory management software.
Root Cause
The root cause of this vulnerability is insufficient input validation and lack of parameterized queries in the /pages/us_edit1.php file. The ID parameter is directly concatenated or interpolated into SQL statements without proper sanitization or escaping. This allows special SQL characters and commands to be interpreted as part of the query structure rather than as data values.
The application does not employ prepared statements or other defensive coding practices that would prevent user input from being treated as executable SQL code.
Attack Vector
The attack can be executed remotely over the network. An attacker can craft malicious HTTP requests targeting the /pages/us_edit1.php endpoint with a specially crafted ID parameter containing SQL injection payloads. No authentication is required to exploit this vulnerability, and no user interaction is needed.
The vulnerability mechanism involves manipulating the ID parameter to break out of the intended SQL query context and inject additional SQL commands. Typical exploitation techniques include UNION-based injection to extract data, boolean-based blind injection to infer database contents, and time-based blind injection when other methods are not viable. For technical details and proof-of-concept information, refer to the GitHub Issue Discussion and VulDB entry #325986.
Detection Methods for CVE-2025-11039
Indicators of Compromise
- Unusual HTTP requests to /pages/us_edit1.php containing SQL keywords (UNION, SELECT, INSERT, UPDATE, DELETE, DROP, OR, AND) in the ID parameter
- Database error messages appearing in application logs or responses indicating SQL syntax errors
- Abnormal database query patterns or execution times suggesting injection attempts
- Unexpected data access or modifications in inventory system database tables
Detection Strategies
- Implement web application firewall (WAF) rules to detect and block SQL injection patterns in HTTP parameters
- Configure database activity monitoring to alert on unusual query patterns or unauthorized data access
- Enable detailed logging on the web server for requests to /pages/us_edit1.php and analyze for injection indicators
- Deploy intrusion detection systems (IDS) with signatures for common SQL injection attack patterns
Monitoring Recommendations
- Monitor web server access logs for requests containing encoded or obfuscated SQL injection payloads targeting the vulnerable endpoint
- Set up alerts for database connection errors or unusual query failures that may indicate injection attempts
- Track and baseline normal application behavior to identify anomalous database query volumes or response times
- Implement real-time monitoring of outbound network traffic for potential data exfiltration attempts
How to Mitigate CVE-2025-11039
Immediate Actions Required
- Restrict access to the /pages/us_edit1.php endpoint using network-level controls or web server configuration until a patch is applied
- Implement input validation rules at the web application firewall level to filter malicious input to the ID parameter
- Review database user permissions and apply the principle of least privilege to limit potential damage from successful exploitation
- Consider temporarily disabling the affected functionality if it is not business-critical
Patch Information
No official vendor patch has been released at this time. Organizations should monitor the Campcodes website for security updates and patch announcements. In the absence of an official fix, applying the workarounds and compensating controls described below is strongly recommended.
Additional technical information about this vulnerability can be found in the VulDB CTI entry and the VulDB submission.
Workarounds
- Deploy a web application firewall (WAF) with SQL injection protection rules to filter malicious requests before they reach the application
- Implement network segmentation to isolate the vulnerable system from critical database infrastructure
- If source code access is available, modify /pages/us_edit1.php to use parameterized queries or prepared statements for the ID parameter
- Apply strict input validation to ensure the ID parameter only accepts expected integer values
# Example: Apache mod_security rule to block SQL injection attempts
# Add to Apache configuration or .htaccess
SecRule ARGS:ID "@detectSQLi" "id:1001,phase:2,deny,status:403,msg:'SQL Injection Attempt Detected'"
# Example: Restrict access to vulnerable endpoint by IP
<Location /pages/us_edit1.php>
Require ip 192.168.1.0/24
</Location>
