CVE-2025-10795 is a medium-severity SQL Injection vulnerability identified in version 1.0 of the code-projects Online Bidding System. The vulnerability resides in the /administrator/bidupdate.php file, specifically involving the manipulation of the 'ID' parameter. An attacker can remotely exploit this flaw without requiring authentication or user interaction. By injecting malicious SQL code into the 'ID' parameter, the attacker can manipulate backend database queries, potentially leading to unauthorized data access, data modification, or disruption of database integrity. The vulnerability has a CVSS 4.0 base score of 6.9, reflecting its network attack vector, low attack complexity, and no privileges or user interaction needed. The impact on confidentiality, integrity, and availability is rated as low individually but combined can lead to significant compromise of the bidding system's data and operations. Although no public exploits are currently known to be actively used in the wild, the disclosure of the vulnerability and its exploitability make it a credible threat. The absence of available patches at this time increases the urgency for mitigation. Given the nature of online bidding systems, which often handle sensitive financial and transactional data, exploitation could lead to unauthorized bid manipulation, financial fraud, or leakage of user information.

For European organizations using the code-projects Online Bidding System version 1.0, this vulnerability poses a risk to the confidentiality and integrity of sensitive bidding and transactional data. Exploitation could allow attackers to alter bids, disrupt auction processes, or extract confidential user and financial information. This could result in financial losses, reputational damage, and regulatory non-compliance, especially under GDPR requirements for protecting personal data. The availability impact is low but could still disrupt business operations temporarily. Organizations relying on this system for critical procurement or sales processes may face operational and financial risks. The remote and unauthenticated nature of the exploit increases the threat level, as attackers can target vulnerable systems over the internet without needing insider access.

Immediate mitigation steps include implementing web application firewalls (WAFs) with rules to detect and block SQL injection attempts targeting the 'ID' parameter in /administrator/bidupdate.php. Organizations should conduct thorough code reviews and apply input validation and parameterized queries or prepared statements to sanitize all inputs, especially the 'ID' parameter. Since no official patches are currently available, consider isolating or restricting access to the administration interface to trusted IP addresses or VPNs to reduce exposure. Regularly monitor logs for suspicious database query patterns or repeated failed attempts. Additionally, organizations should plan for an urgent update or patch deployment once the vendor releases a fix. Conducting penetration testing focused on injection flaws can help identify other potential vulnerabilities in the system. Finally, ensure backups of critical data are current and tested to enable recovery in case of data corruption or loss.
