CVE-2026-2117 identifies a SQL Injection vulnerability in the itsourcecode Society Management System version 1.0, located in the /admin/edit_activity.php file. The vulnerability arises from improper sanitization of the activity_id parameter, which is directly used in SQL queries without adequate validation or parameterization. This allows remote attackers to inject malicious SQL code by manipulating the activity_id argument, potentially enabling unauthorized access to the backend database. The attack vector is network-based (AV:N), requires no authentication (PR:N), and no user interaction (UI:N), making it straightforward to exploit remotely. The impact on confidentiality, integrity, and availability is limited but present (VC:L, VI:L, VA:L), as attackers can read or modify data but not fully compromise the system or escalate privileges. The vulnerability is rated medium severity with a CVSS 4.0 score of 6.9. No patches or fixes have been published yet, and while no exploits are currently observed in the wild, the public availability of exploit code increases the risk of exploitation. The vulnerability primarily affects organizations using the Society Management System 1.0, which is typically deployed for managing community or society activities and member data. The lack of authentication requirement and remote exploitability make this a significant risk for exposed installations.

For European organizations, exploitation of this SQL Injection vulnerability could lead to unauthorized disclosure of sensitive community or society member data, unauthorized modification or deletion of records, and potential disruption of society management operations. This could result in privacy violations under GDPR, reputational damage, and operational downtime. Since the vulnerability does not require authentication, attackers can exploit it remotely without insider access, increasing the attack surface. Organizations relying on this software for managing sensitive or regulated data are at higher risk. The impact is particularly critical for entities managing large membership databases or financial transactions related to society activities. Additionally, the integrity compromise could lead to fraudulent activity or misinformation within society records, affecting trust and compliance.

To mitigate CVE-2026-2117, organizations should immediately implement input validation and sanitization on the activity_id parameter in /admin/edit_activity.php. The preferred approach is to use parameterized queries or prepared statements to prevent SQL Injection. Restrict network access to the admin interface through firewalls or VPNs to limit exposure. Monitor logs for suspicious activity targeting the activity_id parameter or unusual database queries. If possible, upgrade to a patched version once available or apply vendor-supplied patches promptly. Conduct a thorough audit of database integrity and access controls to detect any unauthorized changes. Employ web application firewalls (WAFs) with SQL Injection detection rules as an additional layer of defense. Educate administrators about the risks and signs of exploitation attempts. Finally, consider isolating the Society Management System from critical infrastructure to minimize potential damage.
