CVE-2025-8240 is a SQL Injection vulnerability identified in version 1.0 of the 'code-projects Exam Form Submission' application, specifically within the /user/dashboard.php file. The vulnerability arises from improper sanitization or validation of the 'phone' parameter, which is susceptible to malicious input manipulation. An attacker can remotely exploit this flaw by injecting crafted SQL commands through the 'phone' argument, potentially allowing unauthorized access to the backend database. This could lead to unauthorized data disclosure, data modification, or even complete compromise of the database depending on the database permissions and structure. The vulnerability does not require any authentication or user interaction, making it accessible to unauthenticated remote attackers. The CVSS 4.0 score is 6.9, categorized as medium severity, reflecting the network attack vector, no privileges or user interaction required, but with limited impact on confidentiality, integrity, and availability. Although no known exploits are currently reported in the wild, the public disclosure of the vulnerability increases the risk of exploitation attempts. The lack of available patches or mitigation links indicates that users of the affected software must take immediate protective measures to reduce risk. Since the vulnerability affects a web application component handling user input, it is critical to address it promptly to prevent data breaches or further exploitation.

For European organizations using the 'code-projects Exam Form Submission' software, this vulnerability poses a tangible risk of unauthorized data access or manipulation. Educational institutions or certification bodies relying on this software for exam form submissions could face data integrity issues, exposure of sensitive personal information (such as phone numbers and potentially other linked data), and disruption of services. The ability for unauthenticated remote attackers to exploit this vulnerability increases the threat landscape, potentially leading to reputational damage, regulatory non-compliance (e.g., GDPR violations due to personal data exposure), and operational interruptions. The medium severity rating suggests that while the impact is significant, it may not lead to full system compromise without additional vulnerabilities or misconfigurations. However, the critical classification in the description and the public disclosure heighten the urgency for European entities to assess their exposure and implement mitigations swiftly.

Given the absence of official patches, European organizations should immediately implement the following specific mitigations: 1) Apply strict input validation and sanitization on the 'phone' parameter within /user/dashboard.php to neutralize SQL injection payloads. This can be done by using parameterized queries or prepared statements in the database access layer. 2) Employ Web Application Firewalls (WAFs) configured with rules to detect and block SQL injection attempts targeting the vulnerable endpoint. 3) Conduct thorough code reviews and security testing of the affected application module to identify and remediate similar injection flaws. 4) Restrict database user permissions to the minimum necessary, limiting the potential damage from successful injection attacks. 5) Monitor application logs and network traffic for unusual or suspicious activity related to the 'phone' parameter or dashboard access. 6) If feasible, isolate the vulnerable application environment from critical internal networks until a patch or secure update is available. 7) Engage with the vendor or community maintaining the software to obtain or request an official patch or update addressing this vulnerability. These targeted actions go beyond generic advice by focusing on the specific vulnerable parameter and application context.
