CVE-2025-61246 identifies a critical SQL Injection vulnerability in the indieka900 online-shopping-system-php version 1.0, located in the master/review_action.php script via the proId parameter. SQL Injection (CWE-89) occurs when untrusted input is improperly sanitized and directly embedded into SQL queries, allowing attackers to manipulate the database query logic. In this case, the proId parameter is vulnerable, enabling remote attackers to inject malicious SQL code without requiring authentication or user interaction. The vulnerability is remotely exploitable over the network (AV:N), with low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The impact is severe, affecting confidentiality, integrity, and availability (C:H/I:H/A:H), meaning attackers can exfiltrate sensitive data, alter or delete records, and disrupt service availability. Despite the absence of published patches or known exploits in the wild, the high CVSS score (9.8) reflects the critical nature of this flaw. The vulnerability was reserved in late 2025 and published in early 2026, indicating recent discovery. The indieka900 platform is a PHP-based e-commerce system, and such SQL Injection flaws are common in web applications lacking proper input validation and use of parameterized queries. This vulnerability poses a significant risk to organizations relying on this software for online shopping operations.

For European organizations, exploitation of this vulnerability could lead to severe consequences including unauthorized access to customer data such as personal information and payment details, resulting in data breaches and regulatory non-compliance (e.g., GDPR). Attackers could manipulate product reviews or orders, damaging business reputation and trust. The ability to alter or delete database records could disrupt e-commerce operations, causing downtime and financial losses. Given the critical nature and ease of exploitation, attackers could automate attacks at scale, targeting multiple organizations simultaneously. This threat is particularly impactful for SMEs and retailers using indieka900 or similar PHP-based shopping platforms without robust security controls. Additionally, the breach of customer data could lead to legal penalties and loss of competitive advantage. The lack of available patches increases the urgency for immediate mitigation to prevent exploitation.

Immediate mitigation steps include conducting a thorough code audit focusing on the master/review_action.php file and the handling of the proId parameter. Developers should refactor the code to use parameterized queries or prepared statements to prevent SQL Injection. Implement strict input validation and sanitization for all user-supplied data, especially URL parameters. Deploy Web Application Firewalls (WAFs) with rules targeting SQL Injection patterns to provide a temporary protective layer. Monitor logs for suspicious database query patterns or unexpected errors related to proId. If possible, isolate the vulnerable module or disable review submission functionality until a secure fix is applied. Organizations should also prepare incident response plans in case of exploitation and consider penetration testing to verify the effectiveness of mitigations. Finally, maintain up-to-date backups of databases to enable recovery from potential data corruption or deletion.
