CVE-2025-15353 is a SQL injection vulnerability identified in the itsourcecode Society Management System version 1.0. The flaw resides in the edit_admin_query function located in the /admin/edit_admin_query.php file. The vulnerability arises from improper sanitization of the Username parameter, which can be manipulated by an attacker to inject malicious SQL commands. This injection occurs remotely without requiring authentication or user interaction, making it highly accessible to attackers. The vulnerability allows attackers to execute arbitrary SQL queries against the backend database, potentially leading to unauthorized data disclosure, data modification, or deletion. The CVSS 4.0 base score is 6.9, reflecting a medium severity level due to the lack of authentication and user interaction requirements, but limited scope and impact on confidentiality, integrity, and availability. Although no known exploits in the wild have been reported, the public availability of exploit code increases the risk of exploitation. The vulnerability affects only version 1.0 of the software, and no official patches have been published yet. The lack of input validation and use of unsafe query construction methods are the root causes. This vulnerability is critical for organizations relying on this software for managing society or community data, as attackers could compromise sensitive information or disrupt services.

For European organizations using itsourcecode Society Management System 1.0, this vulnerability poses a significant risk to the confidentiality, integrity, and availability of their data. Attackers exploiting this flaw can gain unauthorized access to sensitive community or society management data, potentially leading to data breaches involving personal or financial information. Data integrity could be compromised by unauthorized modifications or deletions, disrupting organizational operations and trust. Availability may also be affected if attackers execute destructive queries or cause database corruption. Given the remote and unauthenticated nature of the exploit, attackers can launch attacks at scale, increasing the risk of widespread compromise. This is particularly concerning for organizations managing large memberships or sensitive community data. The public availability of exploit code further elevates the threat level, increasing the likelihood of opportunistic attacks. Failure to address this vulnerability could result in regulatory non-compliance, reputational damage, and financial losses for affected European entities.

To mitigate CVE-2025-15353, organizations should immediately implement strict input validation and sanitization on the Username parameter within the edit_admin_query function. Employing parameterized queries or prepared statements is essential to prevent SQL injection attacks. Restrict access to the /admin/edit_admin_query.php endpoint by enforcing strong authentication and role-based access controls, limiting it to trusted administrators only. Monitor logs for unusual query patterns or repeated failed attempts targeting this function. If possible, isolate the database with network segmentation to reduce exposure. Since no official patches are currently available, consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting this vulnerability. Regularly update and audit the software for any new patches or security advisories from the vendor. Additionally, conduct security awareness training for administrators to recognize and respond to suspicious activities. Finally, plan for an upgrade or replacement of the vulnerable software version once a secure release is available.
