CVE-2026-2115 identifies a SQL Injection vulnerability in itsourcecode Society Management System version 1.0, affecting the /admin/delete_expenses.php endpoint. The vulnerability arises from improper handling and sanitization of the expenses_id parameter, which is directly used in SQL queries without adequate validation. This allows a remote attacker to inject malicious SQL code, potentially enabling unauthorized data retrieval, modification, or deletion within the backend database. The attack vector requires no authentication or user interaction, increasing the risk of automated exploitation. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P) indicates network attack vector, low attack complexity, no privileges or user interaction needed, and partial impact on confidentiality, integrity, and availability. Although no official patches or fixes have been published yet, the vulnerability is publicly known, and exploit code has been released, raising the likelihood of future exploitation. The affected product is typically used for managing society or community expenses and related administrative tasks, making the confidentiality and integrity of financial data critical. The vulnerability's exploitation could lead to unauthorized data exposure, financial data manipulation, or denial of service through database corruption or deletion.

The exploitation of CVE-2026-2115 can have significant impacts on organizations using the itsourcecode Society Management System 1.0. Attackers can remotely execute arbitrary SQL commands, potentially leading to unauthorized disclosure of sensitive financial and personal data stored in the database. Integrity of records related to expenses and society management can be compromised, allowing attackers to alter or delete critical data, which may disrupt financial reporting and administrative operations. Availability may also be affected if injected queries cause database crashes or lockups. Since no authentication is required, the attack surface is broad, increasing the risk of automated or mass exploitation attempts. Organizations relying on this software for community or society management could face reputational damage, regulatory compliance issues, and financial losses if the vulnerability is exploited. The absence of official patches further exacerbates the risk, necessitating immediate mitigation efforts to prevent potential breaches.

To mitigate CVE-2026-2115, organizations should implement the following specific measures: 1) Immediately review and sanitize all input parameters, especially expenses_id, using prepared statements or parameterized queries to prevent SQL injection. 2) Restrict access to the /admin/delete_expenses.php endpoint by implementing network-level controls such as IP whitelisting or VPN access to limit exposure. 3) Employ Web Application Firewalls (WAFs) configured to detect and block SQL injection patterns targeting this endpoint. 4) Conduct thorough code audits of the entire application to identify and remediate other potential injection points. 5) Monitor logs for suspicious database query patterns or repeated access attempts to the vulnerable endpoint. 6) If possible, isolate the database with least privilege principles to limit the damage scope in case of exploitation. 7) Engage with the vendor or community to obtain or develop patches and apply them promptly once available. 8) Educate administrators and users about the risks and signs of exploitation to enable rapid incident response. These targeted actions go beyond generic advice by focusing on the specific vulnerable component and its operational context.
