CVE-2025-6469 is a SQL Injection vulnerability identified in version 1.0 of the code-projects Online Bidding System, specifically affecting the /details.php endpoint. The vulnerability arises from improper sanitization or validation of the 'ID' parameter, which is used in database queries. An attacker can remotely manipulate this parameter to inject malicious SQL code, potentially altering the intended database commands. This can lead to unauthorized data access, data modification, or even deletion, depending on the database permissions and the nature of the injected payload. The vulnerability does not require authentication or user interaction, making it exploitable by any remote attacker with network access to the affected system. The CVSS 4.0 score is 6.9 (medium severity), reflecting that while the attack vector is network-based and requires no privileges or user interaction, the impact on confidentiality, integrity, and availability is limited to low levels. The vulnerability scope is local to the affected system, and there is no indication of privilege escalation or widespread impact beyond the compromised instance. No public exploits are currently known in the wild, but the exploit details have been disclosed publicly, increasing the risk of exploitation. No patches or official fixes have been published yet, which leaves systems running version 1.0 exposed to potential attacks. Given the nature of online bidding systems, which often handle sensitive user data and transactional information, exploitation could lead to unauthorized disclosure of bidder identities, bid amounts, or manipulation of auction results, undermining trust and causing financial and reputational damage.

For European organizations using the code-projects Online Bidding System version 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of auction data. Successful exploitation could allow attackers to access sensitive bidder information, manipulate auction details, or disrupt service availability. This could result in financial losses, legal liabilities under GDPR due to data breaches, and damage to organizational reputation. Given the critical role of online bidding platforms in sectors such as government procurement, industrial supply chains, and e-commerce, the impact could extend to operational disruptions and loss of competitive advantage. The medium CVSS score suggests that while the vulnerability is serious, the overall impact may be contained if proper compensating controls are in place. However, the lack of authentication requirements and remote exploitability increase the urgency for mitigation. Organizations relying on this software should consider the risk of targeted attacks, especially in high-value auctions or where sensitive data is processed.

1. Immediate mitigation should involve restricting access to the /details.php endpoint through network-level controls such as IP whitelisting or VPN access to limit exposure to trusted users only. 2. Implement Web Application Firewall (WAF) rules specifically designed to detect and block SQL injection attempts targeting the 'ID' parameter, including payload patterns and anomalous query strings. 3. Conduct a thorough code review and apply input validation and parameterized queries or prepared statements to sanitize the 'ID' parameter, eliminating the injection vector. 4. If possible, upgrade to a newer, patched version of the Online Bidding System once available, or apply vendor-provided patches immediately upon release. 5. Monitor application logs and database logs for suspicious queries or unusual activity related to the 'ID' parameter to detect potential exploitation attempts early. 6. Educate development and operations teams about secure coding practices and the importance of input validation to prevent similar vulnerabilities. 7. As a temporary measure, consider disabling the vulnerable functionality if it is not critical to business operations until a fix is applied.
