CVE-2026-10263: SQL Injection in SourceCodester Computer Repair Shop Management System

CVE-2026-10263: SQL Injection in Computer Repair Shop Management System

A SQL injection vulnerability tracked as CVE-2026-10263 has been identified in SourceCodester's Computer Repair Shop Management System version 1.0. The flaw resides in the /admin/products/manage_product.php endpoint and can be triggered by manipulating the ID parameter. With a CVSS v3.1 score of 7.3 (High), the vulnerability is remotely exploitable and a working public exploit has been published.

Vulnerability Overview

Technical Details

Root Cause

The manage_product.php script passes user-supplied input from the ID GET/POST parameter directly into a SQL query without adequate sanitization or the use of parameterized statements. An attacker who can reach the admin panel — or bypass authentication — can inject arbitrary SQL syntax to manipulate query logic.

Conceptual vulnerable query:

-- Likely server-side behavior
SELECT * FROM products WHERE id = [USER_INPUT]
 
-- Attacker-supplied input
ID = 1 UNION SELECT 1,username,password,4,5 FROM users-- -

Exploitation Path

Attacker (remote, network-accessible)
  → HTTP request to /admin/products/manage_product.php?ID=<payload>
    → Unsanitized ID parameter injected into SQL query
      → Database returns unauthorized data
        → Credentials, PII, or configuration data exfiltrated

Attack Vectors

The CVSS 7.3 score reflects network exploitability with low complexity — once the injection point is confirmed, automated tools such as sqlmap can enumerate the entire database.

Impact Assessment

SourceCodester scripts are widely used in academic and small business environments and are often deployed without security hardening. The public availability of an exploit increases urgency for organizations running this software.

Affected Systems

No patch has been released as of the publication date. Organizations should apply interim mitigations immediately.

Remediation

Immediate Actions

1. Restrict admin panel access — Limit /admin/ directory access to trusted IP ranges using web server configuration or a firewall:

   # Apache .htaccess example
   <Directory "/var/www/html/admin">
     Order deny,allow
     Deny from all
     Allow from 192.168.1.0/24
   </Directory>

   Copy

2. Input validation and parameterized queries — Replace direct string interpolation with prepared statements:

   // Vulnerable pattern
   $query = "SELECT * FROM products WHERE id = " . $_GET['ID'];
    
   // Secure pattern — PDO prepared statement
   $stmt = $pdo->prepare("SELECT * FROM products WHERE id = :id");
   $stmt->execute([':id' => (int) $_GET['ID']]);

   Copy

3. Implement a Web Application Firewall (WAF) — Deploy ModSecurity or a cloud WAF with SQL injection rule sets to detect and block exploitation attempts.

4. Audit database privileges — Ensure the application database user has the minimum required privileges (SELECT only where appropriate), preventing INSERT/UPDATE/DELETE via injected queries.

5. Monitor access logs — Review web server logs for suspicious patterns indicating SQL injection probing:

   grep -i "union\|select\|sleep\|information_schema" /var/log/apache2/access.log

   Copy

6. Rotate credentials — If the system has been exposed, assume database credentials and admin passwords are compromised and rotate immediately.

Detection Indicators

Common SQL injection attack signatures to monitor in logs:

UNION SELECT
OR 1=1
AND 1=2
' OR '1'='1
; DROP TABLE
SLEEP(5)
WAITFOR DELAY
information_schema
@@version

Context: SourceCodester Vulnerabilities

SourceCodester free PHP scripts are frequently targeted by vulnerability researchers and threat actors because they are:

• Widely deployed in small businesses, schools, and development environments
• Rarely maintained with security updates
• Often internet-accessible without authentication hardening

Organizations using any SourceCodester application should conduct a full security audit and consider migration to a maintained alternative.

Key Takeaways

1. CVE-2026-10263 is a CVSS 7.3 SQL injection in the admin product management page of SourceCodester CRMS v1.0
2. The vulnerability is network-exploitable with a public PoC, elevating risk for internet-facing deployments
3. No vendor patch is available — apply firewall restrictions, WAF rules, and parameterized queries immediately
4. Audit all SourceCodester applications in your environment for similar injection points
