CVE-2022-41530 is a high-severity SQL injection vulnerability identified in the Open Source SACCO Management System version 1.0. The vulnerability exists in the 'id' parameter of the endpoint /sacco_shield/ajax.php?action=delete_borrower. SQL injection (CWE-89) occurs when untrusted input is improperly sanitized and directly incorporated into SQL queries, allowing an attacker to manipulate the database query executed by the application. In this case, the 'id' parameter is vulnerable, enabling an attacker with high privileges (PR:H) to execute arbitrary SQL commands remotely (AV:N) without requiring user interaction (UI:N). The vulnerability affects confidentiality, integrity, and availability (C:H/I:H/A:H) of the system, as an attacker could extract sensitive data, modify or delete records, or disrupt service. The CVSS 3.1 base score of 7.2 reflects the ease of exploitation due to low attack complexity (AC:L) and the significant impact on the system. Although no known exploits are currently reported in the wild, the vulnerability poses a serious risk to organizations using this SACCO Management System, which is typically used by Savings and Credit Cooperative Organizations to manage member loans and financial transactions. The lack of vendor or product-specific information limits detailed attribution, but the vulnerability's presence in an open-source financial management tool suggests potential exposure in environments relying on this software for critical financial operations.

For European organizations, particularly those involved in cooperative financial services or microfinance sectors using the Open Source SACCO Management System, this vulnerability could lead to severe consequences. Exploitation could result in unauthorized disclosure of sensitive member financial data, manipulation or deletion of loan records, and disruption of financial services. This could undermine trust in cooperative institutions, lead to financial losses, regulatory penalties under GDPR due to data breaches, and damage to organizational reputation. The high integrity and availability impact means that attackers could alter financial data or cause service outages, potentially affecting operational continuity. Given the financial nature of the application, exploitation could also facilitate fraud or unauthorized financial transactions, increasing the risk exposure for European SACCOs and their members.

To mitigate this vulnerability, organizations should immediately review and sanitize all user inputs, especially the 'id' parameter in the /sacco_shield/ajax.php?action=delete_borrower endpoint, using parameterized queries or prepared statements to prevent SQL injection. Since no official patch is currently available, applying Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection payloads targeting this endpoint can provide interim protection. Conduct thorough code audits to identify and remediate similar injection points throughout the application. Implement strict access controls to limit high-privilege user accounts that can invoke this functionality, reducing the attack surface. Regularly monitor application logs for suspicious database query patterns or repeated failed attempts to exploit the vulnerability. Additionally, organizations should consider isolating the SACCO Management System within segmented network zones to limit lateral movement if compromised. Finally, maintain up-to-date backups of critical financial data to enable recovery in case of data tampering or loss.
