CVE-2025-5332 is a critical SQL Injection vulnerability identified in version 1.0 of the 1000 Projects Online Notice Board application. The vulnerability arises from improper handling of the 'email' parameter in the /index.php file, allowing an attacker to inject malicious SQL code remotely without any authentication or user interaction. This flaw enables attackers to manipulate backend database queries, potentially leading to unauthorized data access, data modification, or even full compromise of the database server. The vulnerability is exploitable over the network (AV:N), requires no privileges (PR:N), no user interaction (UI:N), and has low attack complexity (AC:L). The impact on confidentiality, integrity, and availability is low to limited (VC:L, VI:L, VA:L), indicating that while the attacker can influence the database, the scope of damage may be somewhat constrained by application logic or database permissions. The vulnerability has a CVSS 4.0 base score of 6.9, categorized as medium severity. No public exploits are currently known in the wild, but the exploit details have been disclosed publicly, increasing the risk of exploitation. The lack of available patches or mitigation guidance from the vendor increases the urgency for affected organizations to implement protective measures. Given the nature of SQL Injection, attackers could extract sensitive user data, alter or delete records, or escalate attacks to compromise the underlying server or network infrastructure if combined with other vulnerabilities or misconfigurations.

For European organizations using the 1000 Projects Online Notice Board version 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of stored data, particularly user email addresses and potentially other sensitive information managed by the notice board. Exploitation could lead to data breaches, regulatory non-compliance (e.g., GDPR violations), reputational damage, and operational disruptions. Since the vulnerability is remotely exploitable without authentication, attackers can target exposed web servers from anywhere, increasing the threat landscape. Organizations in sectors such as education, government, and public services that rely on online notice boards for communication may face heightened risks. Additionally, the lack of patches means that without immediate mitigation, these organizations remain exposed. The medium severity rating reflects the potential for impactful data compromise but suggests that the vulnerability might not allow full system takeover without additional flaws. However, the public disclosure of the exploit details could accelerate attack attempts, making timely response critical.

1. Immediate mitigation should include implementing Web Application Firewall (WAF) rules to detect and block SQL injection attempts targeting the 'email' parameter in /index.php. 2. Conduct a thorough code review and input validation to sanitize and parameterize all user inputs, especially the 'email' parameter, to prevent injection attacks. 3. If possible, upgrade or replace the 1000 Projects Online Notice Board application with a version that addresses this vulnerability or switch to alternative secure notice board solutions. 4. Restrict database user permissions to the minimum necessary, limiting the impact of any successful injection. 5. Monitor web server and database logs for suspicious activities indicative of SQL injection attempts. 6. Employ network segmentation and intrusion detection systems to detect and contain potential exploitation. 7. Engage with the vendor or community to obtain patches or security updates as they become available. 8. Educate IT staff about this vulnerability and ensure incident response plans include procedures for SQL injection incidents.
