AnalysisAI

CVE-2025-6470 is a critical SQL injection vulnerability in code-projects Online Bidding System 1.0, specifically in the /bidlog.php file's ID parameter, allowing unauthenticated remote attackers to execute arbitrary SQL queries. The vulnerability has been publicly disclosed with proof-of-concept code available, presenting immediate exploitation risk. With a CVSS score of 7.3 and network-accessible attack vector requiring no authentication, this poses significant risk to confidentiality, integrity, and availability of affected systems.

Technical ContextAI

The vulnerability stems from CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component - 'Injection'), manifesting as SQL injection in a PHP-based web application. The /bidlog.php file fails to properly sanitize or parameterize the 'ID' parameter before incorporating it into SQL queries, allowing attackers to manipulate query logic. This is a classic first-order SQL injection vulnerability in a server-side PHP component. The affected product is code-projects Online Bidding System version 1.0, a web-based application handling auction/bidding functionality. CPE likely maps to vendor 'code-projects' with product identifier 'online_bidding_system' at version '1.0'.
