CVE-2026-3133 identifies a SQL injection vulnerability in the itsourcecode Document Management System version 1.0, specifically within the /loging.php file responsible for user login processing. The vulnerability is triggered by manipulation of the Username parameter, which is not properly sanitized or parameterized before being used in SQL queries. This allows remote attackers to inject arbitrary SQL commands without requiring authentication or user interaction, potentially enabling unauthorized data retrieval, modification, or deletion. The CVSS 4.0 base score is 6.9 (medium severity), reflecting the network attack vector, low attack complexity, and no privileges or user interaction needed. The impact on confidentiality, integrity, and availability is limited but present, as attackers can partially compromise these aspects. No patches or fixes have been officially released yet, and no known exploits are currently active in the wild. However, public disclosure of the vulnerability details increases the risk of exploitation attempts. The vulnerability affects only version 1.0 of the product, which may reduce the overall exposure. The lack of authentication requirement and remote exploitability make this a significant concern for organizations using this document management system, especially those handling sensitive or critical documents.

The SQL injection vulnerability allows attackers to execute arbitrary SQL commands remotely without authentication, potentially leading to unauthorized access to sensitive information stored in the database, data manipulation, or deletion. This compromises the confidentiality, integrity, and availability of the document management system. Organizations relying on this software for managing critical documents could face data breaches, loss of data integrity, or service disruptions. The medium severity score reflects a moderate risk, but the ease of exploitation and remote attack vector increase the threat level. If exploited, attackers could gain insights into user credentials, internal configurations, or other sensitive data, which could be leveraged for further attacks. The absence of known exploits in the wild currently limits immediate widespread impact, but the public disclosure means attackers may develop exploits soon. The impact is particularly significant for organizations in sectors such as government, finance, healthcare, and legal services that depend heavily on document management systems for secure data handling.

1. Immediate mitigation should include restricting access to the /loging.php endpoint through network controls such as firewalls or VPNs to limit exposure to trusted networks only. 2. Implement Web Application Firewall (WAF) rules specifically designed to detect and block SQL injection attempts targeting the Username parameter. 3. Conduct a thorough code review and refactor the login processing code to use parameterized queries or prepared statements to eliminate SQL injection vulnerabilities. 4. Monitor logs for unusual or suspicious SQL query patterns or repeated failed login attempts that may indicate exploitation attempts. 5. If possible, upgrade to a newer, patched version of the itsourcecode Document Management System once available. 6. Employ database-level access controls and least privilege principles to minimize the impact of any successful injection. 7. Educate developers and administrators about secure coding practices and the importance of input validation and sanitization. 8. Regularly back up critical data and verify backup integrity to enable recovery in case of data corruption or deletion caused by exploitation.
