CVE-2025-6472 is a critical SQL Injection vulnerability identified in version 1.0 of the code-projects Online Bidding System, specifically within the /showprod.php file. The vulnerability arises from improper sanitization or validation of the 'ID' parameter, which an attacker can manipulate to inject malicious SQL commands. This flaw allows an unauthenticated remote attacker to execute arbitrary SQL queries on the backend database without requiring any user interaction. The vulnerability affects confidentiality, integrity, and availability of the affected system by potentially exposing sensitive data, modifying or deleting database records, or causing denial of service through database corruption or resource exhaustion. The CVSS 4.0 base score is 6.9 (medium severity), reflecting the network attack vector, low attack 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. The lack of available patches or mitigations from the vendor further elevates the threat level. The Online Bidding System is typically used by organizations to facilitate auctions and bidding processes online, making it a critical component for e-commerce and procurement activities. Exploitation could lead to unauthorized data access, financial fraud, or disruption of business operations.

For European organizations using the code-projects Online Bidding System version 1.0, this vulnerability poses significant risks. Successful exploitation could lead to unauthorized disclosure of sensitive bidding data, including user credentials, bid amounts, and transaction details, undermining confidentiality. Integrity could be compromised by altering bids or auction outcomes, potentially causing financial losses or legal disputes. Availability impacts may arise if attackers execute destructive SQL commands, leading to system downtime and disruption of critical procurement or sales processes. Given the nature of online bidding platforms, sectors such as government procurement, manufacturing, and retail in Europe could face operational and reputational damage. Furthermore, compromised bidding systems may be leveraged as entry points for broader network intrusions or lateral movement within organizational IT environments. The medium CVSS score suggests moderate but tangible risk, especially in environments lacking compensating controls or timely patching.

1. Immediate mitigation should include implementing input validation and parameterized queries or prepared statements in the /showprod.php file to prevent SQL injection. 2. If source code modification is not feasible immediately, deploy Web Application Firewalls (WAFs) with custom rules to detect and block malicious payloads targeting the 'ID' parameter. 3. Conduct thorough code audits of the entire application to identify and remediate similar injection points. 4. Restrict database user privileges to the minimum necessary to limit the impact of potential injection attacks. 5. Monitor application logs and database logs for unusual query patterns or errors indicative of exploitation attempts. 6. Engage with the vendor or community to obtain or develop patches or updates addressing this vulnerability. 7. Implement network segmentation to isolate the bidding system from critical internal networks. 8. Educate development and security teams on secure coding practices to prevent recurrence. 9. Plan for incident response readiness in case exploitation occurs, including data backup and recovery procedures.
