CVE-2025-10833 is a SQL Injection vulnerability identified in version 1.0 of the 1000projects Bookstore Management System, specifically within an unspecified function in the /login.php file. The vulnerability arises from improper sanitization or validation of the 'unm' parameter, which is likely related to the username input during the login process. An attacker can remotely exploit this flaw by injecting malicious SQL code into the 'unm' parameter, allowing unauthorized manipulation of the backend database queries. This can lead to unauthorized data access, modification, or potentially bypassing authentication mechanisms. The vulnerability does not require any authentication or user interaction, making it remotely exploitable over the network. The CVSS 4.0 base score is 6.9, indicating a medium severity level, with attack vector network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction (UI:N). The impact on confidentiality, integrity, and availability is rated low to medium, suggesting limited but non-negligible damage potential. No patches or fixes have been disclosed yet, and there are no known exploits actively used in the wild. However, the public disclosure of the vulnerability increases the risk of exploitation attempts. The vulnerability affects only version 1.0 of the product, which is a niche bookstore management system, potentially limiting the scope of affected installations.

For European organizations using the 1000projects Bookstore Management System version 1.0, this vulnerability poses a risk of unauthorized access to sensitive customer and business data stored in the backend database. Exploitation could lead to data leakage, unauthorized modification of records, or bypassing authentication controls, potentially resulting in financial loss, reputational damage, and regulatory non-compliance under GDPR. Given the nature of the product (bookstore management), the impact may be more pronounced for small to medium-sized enterprises (SMEs) in the retail sector that rely on this software for daily operations. The medium severity rating suggests that while the vulnerability is serious, it may not lead to full system compromise or widespread disruption. However, the lack of authentication and user interaction requirements means attackers can attempt exploitation remotely and at scale if the system is internet-facing. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate it, especially after public disclosure. European organizations should consider the potential for targeted attacks exploiting this vulnerability, particularly those handling sensitive customer payment or personal data.

1. Immediate mitigation should involve restricting external access to the /login.php endpoint through network-level controls such as firewalls or VPNs to limit exposure. 2. Implement input validation and parameterized queries or prepared statements in the /login.php code to prevent SQL injection attacks. Since no official patch is currently available, organizations should review and sanitize the 'unm' parameter handling in the source code if accessible. 3. Conduct thorough code audits and penetration testing focused on SQL injection vectors in all user input fields, not just the login function. 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 software once available or consider alternative bookstore management solutions with better security track records. 6. Educate IT staff about the vulnerability and ensure incident response plans include steps for SQL injection detection and containment. 7. Employ web application firewalls (WAFs) with rules specifically designed to detect and block SQL injection payloads targeting the affected endpoint.
