CVE-2025-10842 is a SQL Injection vulnerability identified in version 1.0 of the code-projects Online Bidding System, specifically within an unknown function in the /administrator/wew.php file. The vulnerability arises from improper sanitization or validation of the 'ID' parameter, allowing an attacker to manipulate this argument to inject malicious SQL code. This injection can be performed remotely without any authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/AT:N/PR:N/UI:N). The vulnerability impacts the confidentiality, integrity, and availability of the backend database, as an attacker could potentially extract sensitive data, modify or delete records, or disrupt service availability. The CVSS score of 6.9 (medium severity) reflects the moderate impact and ease of exploitation. Although no known exploits are currently reported in the wild, the public availability of the exploit code increases the risk of exploitation. The vulnerability does not require authentication or user interaction, making it accessible to a wide range of attackers. The absence of patches or mitigation links suggests that users of this software must take immediate action to protect their systems. Given the nature of online bidding systems, which often handle sensitive user data and financial transactions, exploitation could lead to significant data breaches and financial fraud.

For European organizations using the code-projects Online Bidding System 1.0, this vulnerability poses a significant risk. Exploitation could lead to unauthorized access to sensitive bidder information, including personal and financial data, undermining user trust and potentially violating GDPR regulations. Data integrity could be compromised, allowing attackers to alter bids or auction outcomes, which could result in financial losses and reputational damage. Availability impacts could disrupt auction operations, causing business interruptions. Given the remote and unauthenticated nature of the exploit, attackers could target multiple organizations simultaneously. The public availability of the exploit increases the likelihood of opportunistic attacks, especially against smaller organizations with limited cybersecurity resources. Additionally, regulatory scrutiny in Europe regarding data protection means affected organizations could face legal penalties and mandatory breach notifications, further amplifying the impact.

Organizations should immediately audit their use of the code-projects Online Bidding System version 1.0 and isolate any exposed administrative interfaces such as /administrator/wew.php. Since no official patch is currently available, it is critical to implement web application firewalls (WAFs) with specific rules to detect and block SQL injection attempts targeting the 'ID' parameter. Input validation and parameterized queries should be enforced in the application code to prevent injection. If possible, restrict access to the administration interface by IP whitelisting or VPN-only access to reduce exposure. Regularly monitor logs for suspicious activity related to the 'ID' parameter and unusual database queries. Organizations should also prepare incident response plans to quickly address potential exploitation. Engaging with the vendor for updates or patches and planning for an upgrade or migration to a secure version should be prioritized. Additionally, conducting penetration testing focused on injection vulnerabilities can help identify other potential weaknesses.
