CVE-2025-9749 is a SQL Injection vulnerability identified in the HKritesh009 Grocery List Management Web App, specifically affecting the /src/update.php file. The vulnerability arises from improper sanitization or validation of the 'ID' parameter, which can be manipulated remotely by an unauthenticated attacker to inject malicious SQL queries. This injection flaw allows the attacker to interfere with the application's database queries, potentially leading to unauthorized data access, data modification, or even full database compromise. The vulnerability is exploitable over the network without any authentication or user interaction, increasing the risk of automated exploitation. The product uses a rolling release model, meaning that fixed versions are not clearly delineated, and no official patch or version update information is currently available. The CVSS v4.0 base score is 6.9, indicating a medium severity level, with an exploitability rating of 'Proof-of-Concept' (E:P). The vulnerability impacts confidentiality, integrity, and availability to a limited extent (VC:L, VI:L, VA:L), and no scope change is involved. Although no known exploits are reported in the wild yet, the exploit code is publicly available, which could facilitate attacks by malicious actors.

For European organizations using the HKritesh009 Grocery List Management Web App, this vulnerability poses a significant risk to the confidentiality and integrity of their data. Attackers could leverage the SQL injection to extract sensitive user information, alter grocery list data, or disrupt service availability. While the application is niche, organizations relying on it for internal or customer-facing operations could face data breaches or service interruptions. Given the remote and unauthenticated nature of the exploit, attackers can launch attacks at scale, potentially leading to widespread compromise if the app is deployed in multiple environments. The medium severity rating suggests that while the impact is serious, it may not lead to full system takeover without additional vulnerabilities. However, the lack of available patches and the rolling release model complicate timely remediation, increasing exposure duration. European data protection regulations such as GDPR impose strict requirements on data breach prevention and notification, so affected organizations could face regulatory penalties if they fail to address this vulnerability promptly.

1. Immediate mitigation should involve implementing input validation and parameterized queries or prepared statements in the /src/update.php file to prevent SQL injection attacks. 2. Conduct a thorough code review of the entire application to identify and remediate any other injection points or insecure coding practices. 3. If possible, deploy a Web Application Firewall (WAF) with rules specifically designed to detect and block SQL injection attempts targeting the 'ID' parameter. 4. Monitor application logs for unusual database query patterns or repeated failed attempts that could indicate exploitation attempts. 5. Engage with the vendor or development team to obtain or request a security patch or update, even if the rolling release model complicates version tracking. 6. Consider isolating or restricting access to the application to trusted networks until a fix is applied. 7. Educate development teams on secure coding practices to prevent similar vulnerabilities in future releases. 8. Regularly back up databases and ensure backups are stored securely to enable recovery in case of data tampering or loss.
