CVE-2025-10667 is a SQL Injection vulnerability identified in the itsourcecode Online Discussion Forum version 1.0. The vulnerability exists in the /members/compose_msg.php file, specifically through manipulation of the 'ID' parameter. This parameter is not properly sanitized, allowing an attacker to inject malicious SQL code remotely without any authentication or user interaction. The injection flaw can lead to unauthorized access or modification of the backend database, potentially exposing sensitive user data or enabling further compromise of the application. The CVSS 4.0 base score of 6.9 reflects a medium severity, indicating that while the attack vector is network-based and requires no privileges or user interaction, the impact on confidentiality, integrity, and availability is limited to low levels individually but combined can be significant. The vulnerability is publicly known, and exploit code is available, increasing the risk of exploitation. However, there are no known active exploits in the wild at this time. No official patches have been released yet, which means affected installations remain vulnerable. The lack of authentication requirement and remote exploitability make this a notable risk for any organization using this forum software, especially if sensitive communications or personal data are stored within the forum database.

For European organizations using the itsourcecode Online Discussion Forum 1.0, this vulnerability poses a risk of unauthorized data disclosure, data manipulation, or potential disruption of forum services. Given that forums often contain user-generated content, private messages, and possibly sensitive organizational discussions, exploitation could lead to leakage of confidential information or reputational damage. Additionally, attackers might leverage this vulnerability as a foothold to pivot into broader internal networks if the forum is hosted within corporate infrastructure. The medium severity suggests that while immediate catastrophic damage is unlikely, the cumulative effect of data breaches or service interruptions could be significant, especially under the stringent data protection regulations such as GDPR. Organizations failing to secure or monitor these forums might face compliance issues and potential fines if personal data is compromised.

To mitigate this vulnerability, European organizations should first verify if they are running itsourcecode Online Discussion Forum version 1.0. Since no official patch is currently available, immediate steps include implementing web application firewall (WAF) rules to detect and block SQL injection attempts targeting the 'ID' parameter in /members/compose_msg.php. Input validation and parameterized queries should be enforced at the application level if source code access is possible. Network segmentation should isolate the forum server from critical internal systems to limit lateral movement in case of compromise. Regular monitoring of logs for suspicious database queries or unusual forum activity is recommended. Organizations should also consider temporarily disabling the vulnerable functionality or restricting access to trusted IP addresses until a patch or upgrade is available. Finally, planning for an upgrade to a patched or newer version of the forum software once released is critical for long-term security.
