CVE-2025-12329 identifies a SQL injection vulnerability in the shawon100 RUET OJ platform, a system likely used for online judging or educational purposes. The flaw resides in an unspecified function within the /details.php file, where the ID parameter is not properly sanitized, allowing an attacker to inject arbitrary SQL commands. This injection can be performed remotely without requiring authentication or user interaction, increasing the attack surface. The vulnerability has a CVSS 4.0 base score of 5.3 (medium severity), reflecting limited but notable impact on confidentiality, integrity, and availability with low complexity of attack. The rolling release nature of the product means affected versions are difficult to pinpoint, complicating patch management. The vendor has not responded to early disclosure attempts, and no official patches or updates have been published. Although no confirmed exploits in the wild exist, public proof-of-concept code is available, increasing the risk of exploitation. This vulnerability could allow attackers to extract sensitive data, modify database contents, or disrupt service availability. The lack of authentication and user interaction requirements means automated attacks or mass scanning could be effective. The threat is particularly relevant for organizations running this platform or similar educational tools, which may store user data, contest results, or other sensitive information.

For European organizations, especially educational institutions or competitive programming platforms using shawon100 RUET OJ, this vulnerability poses a risk of unauthorized data access, data manipulation, and service disruption. Confidentiality could be compromised through data leakage of user credentials, contest data, or personal information. Integrity risks include unauthorized modification of database records, potentially affecting contest results or user data. Availability could be impacted if attackers exploit the vulnerability to cause database errors or denial of service. Given the remote and unauthenticated nature of the exploit, attackers could automate attacks at scale, increasing exposure. The medium CVSS score suggests moderate impact, but the presence of public exploit code elevates the urgency. European organizations with limited security monitoring or patch management may be particularly vulnerable. Additionally, the vendor's lack of response and absence of patches complicate remediation efforts, increasing risk exposure over time.

1. Immediately implement input validation and sanitization on the ID parameter in /details.php to prevent SQL injection. 2. Refactor database queries to use parameterized statements or prepared queries, eliminating direct concatenation of user inputs. 3. Conduct a comprehensive code review of the entire application to identify and remediate similar injection points. 4. Deploy Web Application Firewalls (WAFs) with rules targeting SQL injection patterns specific to this vulnerability. 5. Monitor database logs and application logs for unusual query patterns or errors indicative of exploitation attempts. 6. If possible, isolate the affected service behind network segmentation to limit exposure. 7. Engage with the vendor or community to track any forthcoming patches or updates, and apply them promptly. 8. Educate developers and administrators on secure coding practices and the importance of timely patching. 9. Consider temporary mitigation by restricting access to the /details.php endpoint to trusted users or IP ranges until a patch is available. 10. Maintain regular backups of the database to enable recovery in case of data manipulation or corruption.
