CVE-2025-10841 is a SQL Injection vulnerability identified in version 1.0 of the code-projects Online Bidding System, specifically within the /administrator/weweee.php file. The vulnerability arises due to improper sanitization or validation of the 'ID' parameter, which allows an attacker to manipulate SQL queries executed by the application. This manipulation can be performed remotely without requiring authentication or user interaction, making it a significant risk. Exploiting this vulnerability could allow an attacker to execute arbitrary SQL commands on the backend database, potentially leading to unauthorized data disclosure, data modification, or deletion. 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 known in the wild, the vulnerability has been publicly disclosed, increasing the risk of exploitation by opportunistic attackers. The affected product is an online bidding system, which typically handles sensitive user data, bidding information, and possibly financial transactions, making the vulnerability particularly concerning in contexts where data integrity and confidentiality are critical.

For European organizations using the code-projects Online Bidding System 1.0, this vulnerability poses a risk of unauthorized access to sensitive bidding data, user credentials, and potentially financial information. Exploitation could lead to data breaches, manipulation of bidding outcomes, and disruption of auction processes, undermining trust and causing financial losses. Given the remote and unauthenticated nature of the attack, threat actors could target these systems en masse, especially if they are exposed to the internet. The impact extends beyond confidentiality to integrity and availability, as attackers could alter bids or disrupt system operations. Organizations in sectors such as e-commerce, government procurement, and financial services that rely on online bidding platforms are particularly vulnerable. Additionally, compliance with GDPR and other data protection regulations in Europe means that exploitation could result in regulatory penalties and reputational damage.

To mitigate this vulnerability, organizations should immediately apply any available patches or updates from the vendor; however, no patch links are currently provided, so contacting the vendor for a fix is critical. In the interim, implement input validation and sanitization on the 'ID' parameter to prevent malicious SQL code injection. Employ web application firewalls (WAFs) configured to detect and block SQL injection attempts targeting the /administrator/weweee.php endpoint. Restrict access to the administration interface by IP whitelisting or VPN to limit exposure. Conduct thorough code reviews and penetration testing focused on SQL injection vectors within the application. Additionally, monitor logs for suspicious query patterns or repeated access attempts to the vulnerable parameter. Consider migrating to a more secure or updated bidding system if remediation is delayed. Finally, ensure regular backups of the database to enable recovery in case of data tampering or loss.
