CVE-2025-5432 is a SQL Injection vulnerability identified in AssamLook CMS version 1.0, specifically within the /view_tender.php file. The vulnerability arises from improper sanitization or validation of the 'ID' parameter, which is directly used in SQL queries. This flaw allows an unauthenticated remote attacker to manipulate the SQL query logic by injecting malicious SQL code through the 'ID' argument. The injection can lead to unauthorized access to the backend database, enabling attackers to read, modify, or delete sensitive data, potentially compromising the confidentiality and integrity of the system. The vulnerability does not require user interaction or authentication, increasing its risk profile. Although the CVSS 4.0 score is 5.3 (medium severity), the attack vector is network-based with low attack complexity and no privileges required, which typically elevates the risk. The vendor has been notified but has not responded or issued a patch, and no known exploits have been observed in the wild yet. Given the public disclosure of the exploit details, the risk of exploitation may increase rapidly. AssamLook CMS is a content management system, and the affected functionality appears to be related to tender or procurement information, which may contain sensitive business or governmental data. The lack of vendor response and patch availability heightens the urgency for organizations using this CMS to implement mitigations promptly.

For European organizations using AssamLook CMS 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of their data. Attackers exploiting this SQL injection could access sensitive procurement or tender information, potentially leading to data breaches, intellectual property theft, or manipulation of critical business processes. The availability impact is limited but could occur if attackers execute destructive SQL commands. Given the remote and unauthenticated nature of the exploit, attackers can target vulnerable systems over the internet without needing credentials, increasing the attack surface. This is particularly concerning for public sector entities or private companies involved in government contracts or sensitive supply chains. The lack of vendor patches means organizations must rely on compensating controls, increasing operational complexity and risk. Additionally, public disclosure may attract opportunistic attackers, increasing the likelihood of exploitation attempts within Europe.

1. Immediate mitigation should include implementing web application firewall (WAF) rules to detect and block malicious SQL injection payloads targeting the 'ID' parameter in /view_tender.php. 2. Conduct thorough input validation and sanitization on all user-supplied parameters, especially 'ID', using parameterized queries or prepared statements to prevent injection. 3. If possible, restrict access to the vulnerable endpoint via network segmentation or IP whitelisting to limit exposure. 4. Monitor web server and database logs for unusual query patterns or errors indicative of injection attempts. 5. Consider deploying runtime application self-protection (RASP) solutions to detect and block injection attacks dynamically. 6. Plan for migration or upgrade to a more secure CMS platform if AssamLook CMS is no longer maintained or patched. 7. Engage with the vendor or community for any unofficial patches or mitigations. 8. Educate security teams and developers about this vulnerability and ensure incident response plans are updated to address potential exploitation.
