CVE-2025-10802 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/remove.php file. The vulnerability arises from improper sanitization or validation of the 'ID' parameter, which is manipulated by an attacker to inject malicious SQL code. This injection flaw allows remote attackers to execute arbitrary SQL commands on the backend database without requiring any authentication or user interaction. The CVSS 4.0 score of 6.9 (medium severity) reflects that the attack vector is network-based with low complexity and no privileges or user interaction needed, but the impact on confidentiality, integrity, and availability is limited to low levels. The vulnerability could allow attackers to read, modify, or delete data within the database, potentially compromising sensitive bidding information or administrative data. Although no known exploits are currently observed in the wild, the exploit code has been published, increasing the risk of exploitation. The lack of available patches or mitigations from the vendor further elevates the urgency for organizations using this system to implement protective measures.

For European organizations utilizing the code-projects Online Bidding System 1.0, this vulnerability poses a tangible risk to the confidentiality and integrity of their bidding data and administrative controls. Successful exploitation could lead to unauthorized data disclosure, manipulation of bidding records, or disruption of auction processes, undermining trust and operational continuity. Given that the vulnerability requires no authentication and can be exploited remotely, attackers could leverage it to gain persistent access or pivot within the network. This is particularly concerning for organizations handling sensitive procurement or auction data, including government agencies, financial institutions, and commercial enterprises. The medium severity rating suggests that while the impact is not catastrophic, it can cause significant operational and reputational damage if exploited. Additionally, the absence of patches means organizations must rely on compensating controls to mitigate risk.

1. Immediate implementation of Web Application Firewall (WAF) rules to detect and block SQL injection attempts targeting the /administrator/remove.php endpoint, specifically filtering suspicious 'ID' parameter inputs. 2. Restrict network access to the administration interface by implementing IP whitelisting or VPN-only access to reduce exposure to external attackers. 3. Conduct thorough input validation and parameterized query enforcement in the application code to sanitize all user-supplied inputs, especially the 'ID' parameter, to prevent injection. 4. Monitor application logs and database query logs for anomalous activities indicative of SQL injection attempts. 5. If feasible, isolate the affected system within a segmented network zone to limit lateral movement in case of compromise. 6. Engage with the vendor or development team to obtain or develop patches or updates addressing this vulnerability. 7. Educate administrators and developers on secure coding practices and the importance of timely patching and vulnerability management.
