CVE-2026-3068 identifies a SQL injection vulnerability in the itsourcecode Document Management System version 1.0, specifically in the /deluser.php script through the user2del parameter. SQL injection occurs when untrusted input is improperly sanitized and directly included in SQL queries, allowing attackers to manipulate the database query logic. In this case, an attacker can remotely send crafted input to the user2del parameter, which is not properly validated or parameterized, leading to injection of malicious SQL commands. This can result in unauthorized data retrieval, modification, or deletion within the backend database. The vulnerability requires no authentication or user interaction, making it easier to exploit remotely. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L) reflects network attack vector, low attack complexity, no privileges or user interaction needed, and low impact on confidentiality, integrity, and availability individually, but combined they pose a medium risk. The exploit code has been publicly disclosed, increasing the likelihood of exploitation attempts. No official patches have been linked yet, so mitigation relies on secure coding practices or temporary workarounds. This vulnerability affects only version 1.0 of the product, which may still be in use in some organizations.

The SQL injection vulnerability in itsourcecode Document Management System 1.0 can lead to unauthorized access to sensitive data stored in the backend database, including user credentials, documents, or configuration data. Attackers could modify or delete data, potentially disrupting document management operations and causing data integrity issues. The ability to execute arbitrary SQL commands remotely without authentication increases the risk of data breaches and system compromise. Organizations relying on this system for document storage and management may face operational downtime, reputational damage, and compliance violations if exploited. Although the impact on confidentiality, integrity, and availability is rated low individually, the combined effect and ease of exploitation elevate the risk to medium severity. The lack of known exploits in the wild currently limits immediate widespread impact, but public exploit availability raises the threat level. The vulnerability could be leveraged as an initial access vector in broader attack campaigns targeting organizations using this software.

1. Apply vendor-provided patches or updates as soon as they become available to address the vulnerability directly. 2. If patches are not yet available, implement input validation and sanitization on the user2del parameter to reject or neutralize malicious SQL syntax. 3. Use parameterized queries or prepared statements in the /deluser.php code to prevent direct injection of user input into SQL commands. 4. Restrict access to the /deluser.php endpoint via network controls such as firewalls or VPNs to limit exposure to untrusted networks. 5. Monitor logs for suspicious activity targeting the user2del parameter or unusual database query patterns. 6. Conduct a thorough security review of the entire application for similar injection flaws. 7. Educate developers on secure coding practices to prevent SQL injection vulnerabilities in future releases. 8. Consider deploying Web Application Firewalls (WAFs) with rules to detect and block SQL injection attempts targeting this parameter. 9. Maintain regular backups of critical data to enable recovery in case of data tampering or deletion.
