CVE-2025-10033 is a SQL Injection vulnerability identified in version 1.0 of the itsourcecode Online Discussion Forum software. The vulnerability exists in an unspecified function within the /admin path, specifically involving manipulation of the 'Username' argument. This flaw allows an unauthenticated remote attacker to inject malicious SQL code into the backend database queries. The injection can lead to unauthorized data access, modification, or deletion, potentially compromising the confidentiality, integrity, and availability of the forum's data. The vulnerability does not require any user interaction or privileges, making it accessible to any remote attacker. The CVSS 4.0 base score is 6.9 (medium severity), reflecting the ease of exploitation (no authentication or user interaction required) but limited impact scope (low confidentiality, integrity, and availability impacts). No known exploits are currently observed in the wild, and no patches have been published yet. The vulnerability disclosure date is September 6, 2025.

For European organizations using the itsourcecode Online Discussion Forum 1.0, this vulnerability poses a significant risk to the security of their discussion platforms. Exploitation could lead to unauthorized access to sensitive user data, including credentials and private communications, which may violate GDPR and other data protection regulations. Integrity of forum content could be compromised, allowing attackers to alter or delete posts, potentially damaging organizational reputation and trust. Availability impacts could disrupt communication channels critical for internal or customer-facing operations. Given the remote and unauthenticated nature of the exploit, attackers could easily target vulnerable installations, increasing the risk of widespread compromise. Organizations in sectors with high regulatory scrutiny or those relying heavily on online community engagement are particularly at risk.

Organizations should immediately assess their use of the itsourcecode Online Discussion Forum version 1.0 and plan to upgrade to a patched version once available. In the absence of an official patch, applying web application firewall (WAF) rules to detect and block SQL injection patterns targeting the 'Username' parameter in the /admin endpoint is recommended. Input validation and parameterized queries should be implemented to sanitize user inputs. Restricting access to the /admin path via IP whitelisting or VPN-only access can reduce exposure. Continuous monitoring of logs for suspicious SQL query patterns and anomalous admin access attempts is advised. Additionally, organizations should conduct security audits and penetration testing focused on injection flaws in their web applications. Finally, maintaining regular backups of forum data will aid in recovery if an attack occurs.
