CVE-2025-5430 is a SQL Injection vulnerability identified in AssamLook CMS version 1.0, specifically affecting the /product.php file through manipulation of the 'ID' parameter. SQL Injection vulnerabilities occur when untrusted input is improperly sanitized and directly included in SQL queries, allowing attackers to execute arbitrary SQL commands on the backend database. This can lead to unauthorized data access, data modification, or even full system compromise depending on the database privileges. The vulnerability is remotely exploitable without user interaction or authentication, increasing the risk profile. Although the CVSS 4.0 score is 5.3 (medium severity), the description classifies it as critical, indicating potential underestimation of impact. The vendor has not responded to disclosure requests, and no patches or mitigations have been released. No known exploits are currently reported in the wild, but public disclosure increases the likelihood of exploitation attempts. The vulnerability’s impact depends on the database backend and the CMS deployment context, but typical risks include data leakage, data integrity loss, and potential pivoting within the network. The lack of authentication and user interaction requirements makes this vulnerability particularly dangerous for exposed web servers running AssamLook CMS 1.0.

For European organizations using AssamLook CMS 1.0, this vulnerability poses a significant risk to the confidentiality, integrity, and availability of their web applications and underlying data. Attackers exploiting this SQL Injection could extract sensitive customer or business data, modify product information, or disrupt service availability. This could lead to regulatory compliance violations under GDPR due to unauthorized data disclosure, resulting in legal and financial penalties. Additionally, compromised CMS instances could serve as footholds for further attacks within organizational networks, increasing overall cyber risk. The absence of vendor patches means organizations must rely on alternative mitigations or consider immediate CMS upgrades or replacements. The medium CVSS score may underestimate the real-world impact, especially if the CMS is used to manage critical business functions or sensitive data. The remote and unauthenticated nature of the exploit increases the likelihood of automated scanning and exploitation attempts, particularly targeting publicly accessible web servers.

Given the lack of official patches, European organizations should take immediate steps to mitigate risk: 1) Implement Web Application Firewalls (WAFs) with custom rules to detect and block SQL Injection attempts targeting the /product.php endpoint and the 'ID' parameter. 2) Conduct thorough input validation and sanitization on all user-supplied parameters, especially 'ID', using parameterized queries or prepared statements if possible. 3) Restrict database user privileges associated with the CMS to the minimum necessary to limit damage from potential exploitation. 4) Monitor web server and application logs for suspicious activity indicative of SQL Injection attempts. 5) If feasible, isolate or temporarily disable the vulnerable CMS instance until a patch or upgrade is available. 6) Consider migrating to a more secure and actively maintained CMS platform. 7) Educate IT and security teams about this vulnerability and ensure incident response plans include detection and containment strategies for SQL Injection attacks. 8) Regularly back up CMS data and configurations to enable rapid recovery in case of compromise.
