CVE-2025-7167 is a SQL Injection vulnerability identified in version 1.0 of the code-projects Responsive Blog Site, specifically within the /category.php file. The vulnerability arises due to improper sanitization or validation of the 'ID' parameter, which is used in SQL queries. 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 is exploitable without user interaction and does not require prior authentication, increasing its risk profile. The CVSS 4.0 score is 5.3 (medium severity), reflecting the fact that while the attack vector is network-based and requires low attack complexity, the impact on confidentiality, integrity, and availability is limited to low levels. The vulnerability has been publicly disclosed, but no known exploits are currently active in the wild. The lack of a patch link suggests that a fix may not yet be available, or it has not been publicly released. Given the nature of SQL Injection, successful exploitation could lead to data leakage, unauthorized data modification, or disruption of service, depending on the database privileges and application logic. However, the limited impact ratings suggest that the vulnerability might be constrained by additional mitigating factors such as limited database permissions or partial query control.

For European organizations using the Responsive Blog Site 1.0, this vulnerability poses a risk of unauthorized data access or manipulation, which could lead to data breaches involving sensitive or personal data. This is particularly critical under the GDPR framework, where unauthorized exposure of personal data can result in significant regulatory penalties. The vulnerability could also be leveraged to deface websites or disrupt service availability, impacting organizational reputation and operational continuity. Since the vulnerability is remotely exploitable without authentication, attackers could target publicly accessible blog sites to gain footholds or extract data. However, the medium severity and low impact on confidentiality and integrity suggest that the overall damage might be limited unless combined with other vulnerabilities or misconfigurations. Organizations relying on this software for public-facing content should be aware of the potential for exploitation and the associated compliance and reputational risks.

1. Immediate mitigation should include implementing input validation and parameterized queries or prepared statements in the /category.php file to prevent SQL Injection. 2. If source code modification is not feasible immediately, deploying a Web Application Firewall (WAF) with rules to detect and block SQL Injection attempts targeting the 'ID' parameter can reduce risk. 3. Conduct a thorough audit of database permissions to ensure the application uses the least privilege principle, limiting the potential impact of any injection. 4. Monitor web server and application logs for suspicious query patterns or repeated access attempts to /category.php with unusual parameter values. 5. Engage with the vendor or community to obtain or develop an official patch and apply it promptly once available. 6. Consider isolating or restricting access to the vulnerable application if it hosts sensitive data, until a fix is applied. 7. Educate development and security teams about secure coding practices to prevent similar vulnerabilities in future releases.
