CVE-2025-6343 is a SQL Injection vulnerability identified in version 1.0 of the code-projects Online Shoe Store application, specifically within the /admin/admin_product.php file. The vulnerability arises from improper sanitization or validation of the 'pid' parameter, which is used in SQL queries. An attacker can remotely exploit this flaw by manipulating the 'pid' argument to inject malicious SQL code, potentially allowing unauthorized access to the underlying database. This could lead to unauthorized data disclosure, modification, or deletion of sensitive information such as product details, user data, or administrative credentials. The vulnerability does not require authentication or user interaction, making it accessible to unauthenticated remote attackers. The CVSS 4.0 base score is 6.9, categorized as medium severity, with an attack vector of network (remote), low attack complexity, no privileges required, and no user interaction needed. The impact on confidentiality, integrity, and availability is rated as low individually, but combined they pose a significant risk. Although no known exploits are currently observed in the wild, the public disclosure of the exploit code increases the likelihood of exploitation. The absence of patches or mitigation links indicates that the vendor has not yet released an official fix, increasing the urgency for organizations to implement protective measures.

For European organizations using the code-projects Online Shoe Store 1.0 platform, this vulnerability presents a tangible risk of data breaches and operational disruption. Exploitation could lead to unauthorized access to sensitive customer and business data, undermining confidentiality and potentially violating GDPR regulations, which impose strict data protection requirements and heavy penalties for breaches. Integrity of product and transactional data could be compromised, leading to fraudulent transactions or misinformation. Availability impact is limited but possible if attackers execute destructive SQL commands. Retailers and e-commerce businesses relying on this software may face reputational damage, financial losses, and legal consequences. Given the remote and unauthenticated nature of the exploit, attackers can easily scan for vulnerable instances across Europe, increasing the threat surface. The medium CVSS score suggests moderate risk, but the critical classification in the description and public exploit disclosure warrant heightened attention.

1. Immediate implementation of Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the 'pid' parameter in /admin/admin_product.php. 2. Conduct thorough input validation and sanitization on all user-supplied inputs, especially the 'pid' parameter, using parameterized queries or prepared statements to prevent injection. 3. Restrict access to the /admin/ directory via IP whitelisting or VPN-only access to reduce exposure of the vulnerable endpoint. 4. Monitor application logs for unusual SQL errors or suspicious query patterns indicative of injection attempts. 5. If possible, isolate the affected application environment and conduct a security audit to identify any signs of compromise. 6. Engage with the vendor or community to obtain or develop patches; if unavailable, consider upgrading to a more secure e-commerce platform. 7. Educate administrative users on the risks and encourage strong authentication mechanisms to mitigate potential lateral movement post-exploitation. 8. Regularly back up databases and verify backup integrity to enable recovery in case of data tampering or loss.
