CVE-2025-10791 is a SQL Injection vulnerability identified in version 1.0 of the code-projects Online Bidding System, specifically within an unspecified function in the /administrator/index.php file. The vulnerability arises from improper sanitization or validation of the 'aduser' argument, which allows an attacker to inject malicious SQL code remotely without requiring authentication or user interaction. This flaw enables an attacker to manipulate backend database queries, potentially leading to unauthorized data access, data modification, or disruption of service. The CVSS 4.0 base score is 6.9 (medium severity), reflecting the network attack vector, low complexity, no privileges or user interaction required, and limited impact on confidentiality, integrity, and availability. Although no public exploits are currently observed in the wild, the exploit code has been made publicly available, increasing the risk of exploitation. The vulnerability affects only version 1.0 of the product, which is an online bidding platform likely used by organizations to manage auctions or sales online. The lack of patches or mitigation links indicates that no official fix has been released yet, emphasizing the need for immediate defensive measures.

For European organizations using the code-projects Online Bidding System 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of sensitive bidding data and user information. Attackers exploiting this SQL Injection could extract confidential bidder details, manipulate auction results, or disrupt the availability of the bidding platform, potentially causing financial losses and reputational damage. Given the administrative context of the vulnerable endpoint, successful exploitation could also lead to privilege escalation or full system compromise if combined with other vulnerabilities. The medium severity score suggests a moderate but tangible threat, especially for organizations relying heavily on this system for critical procurement or sales processes. Additionally, the public availability of exploit code increases the likelihood of opportunistic attacks, making timely mitigation crucial. Compliance with European data protection regulations (e.g., GDPR) could be jeopardized if personal data is exposed or altered due to this vulnerability.

1. Immediate isolation or temporary disabling of the affected /administrator/index.php functionality until a patch or fix is available. 2. Implement strict input validation and parameterized queries or prepared statements for all database interactions involving the 'aduser' parameter to prevent SQL Injection. 3. Conduct a thorough code review of the entire application to identify and remediate any other potential injection points. 4. Deploy Web Application Firewalls (WAF) with custom rules to detect and block SQL Injection attempts targeting the vulnerable parameter. 5. Monitor logs for unusual database query patterns or repeated access attempts to the vulnerable endpoint. 6. If possible, upgrade to a newer, patched version of the Online Bidding System once released by the vendor. 7. Educate system administrators and developers on secure coding practices and the importance of timely patching. 8. Consider network segmentation to limit access to the administrative interface only to trusted IP addresses or VPN users.
