CVE-2025-8270 is a critical SQL Injection vulnerability identified in version 1.0 of the code-projects Exam Form Submission application. The vulnerability resides in the /admin/delete_s2.php file, specifically through improper sanitization of the 'ID' parameter. An attacker can remotely manipulate this parameter to inject malicious SQL code, potentially allowing unauthorized access to or modification of the backend database. The vulnerability requires no authentication or user interaction, making it remotely exploitable over the network. The CVSS 4.0 score is 6.9 (medium severity) with vector AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P, indicating the attack can be performed remotely with low complexity and no privileges or user interaction needed. The impact on confidentiality, integrity, and availability is limited but present, as the vulnerability allows partial compromise of the database. No official patches have been published yet, and although no exploits are currently known in the wild, public disclosure of the exploit code increases the risk of exploitation. The vulnerability affects only version 1.0 of the product, which is a niche web application used for exam form submissions, likely deployed in educational or administrative environments.

For European organizations, especially educational institutions or administrative bodies using the code-projects Exam Form Submission 1.0 software, this vulnerability poses a significant risk. Exploitation could lead to unauthorized data access, including sensitive student or exam data, modification or deletion of records, and potential disruption of exam administration processes. This could result in data breaches violating GDPR regulations, reputational damage, and operational downtime. Since the vulnerability is remotely exploitable without authentication, attackers could leverage it to gain footholds within networks or pivot to other systems. The lack of patches and public exploit disclosure heightens the urgency for mitigation. Organizations relying on this software must assess their exposure and implement compensating controls promptly to prevent data compromise and service disruption.

1. Immediate mitigation should include restricting access to the /admin/delete_s2.php endpoint via network-level controls such as IP whitelisting or VPN-only access to limit exposure. 2. Implement web application firewall (WAF) rules to detect and block SQL injection patterns targeting the 'ID' parameter. 3. If possible, disable or remove the vulnerable functionality until a patch is available. 4. Conduct thorough input validation and parameterized queries in the application code to prevent SQL injection. 5. Monitor logs for suspicious activity related to the 'ID' parameter and unusual database queries. 6. Engage with the vendor or community to obtain or develop patches and apply them promptly once available. 7. Perform a risk assessment and consider isolating the affected system from critical networks to limit lateral movement. 8. Educate administrators about the vulnerability and ensure incident response plans are updated to handle potential exploitation.
