CVE-2025-13264 identifies a SQL injection vulnerability in the SourceCodester Online Magazine Management System version 1.0, affecting the /view_magazine.php script. The vulnerability arises from improper sanitization of the 'ID' parameter, which is directly used in SQL queries without adequate validation or parameterization. This flaw enables remote attackers to inject malicious SQL code, potentially allowing unauthorized data access, modification, or deletion within the backend database. The attack vector requires no user interaction and no authentication, increasing its risk profile. The CVSS 4.0 score of 5.3 reflects a medium severity, considering the attack complexity is low, but the impact on confidentiality, integrity, and availability is limited to partial compromise. Although no active exploitation in the wild is reported, the public release of exploit code increases the likelihood of attacks. The vulnerability affects only version 1.0 of the product, with no patches currently linked, indicating that organizations must implement manual mitigations or seek vendor updates. The vulnerability's exploitation could lead to unauthorized disclosure of sensitive magazine content, alteration of published information, or denial of service through database manipulation. The lack of scope change and absence of privilege requirements limit the overall impact but still pose a significant risk to affected deployments.

For European organizations, especially those in the media, publishing, and online content sectors using SourceCodester Online Magazine Management System 1.0, this vulnerability poses a risk of unauthorized data access and potential data integrity violations. Attackers could extract sensitive editorial content, user data, or internal configuration details, leading to reputational damage and regulatory compliance issues under GDPR. The ability to modify or delete data could disrupt publication workflows and availability of online magazines, impacting business continuity. Given the remote exploitability without authentication, attackers from anywhere could target vulnerable systems, increasing the threat landscape. The medium severity suggests that while the impact is not catastrophic, it is sufficient to warrant immediate attention to prevent exploitation. Organizations lacking timely patching or mitigation may face increased risk of targeted attacks or opportunistic scanning by automated tools. The potential for data breaches could also trigger legal and financial consequences under European data protection laws.

European organizations should implement the following specific mitigations: 1) Immediately audit all instances of SourceCodester Online Magazine Management System version 1.0 and isolate vulnerable deployments. 2) Apply strict input validation and sanitization on the 'ID' parameter in /view_magazine.php, preferably replacing dynamic SQL queries with parameterized prepared statements to prevent injection. 3) Restrict database user permissions to the minimum necessary, avoiding use of highly privileged accounts for web application database connections. 4) Monitor web application logs for unusual or malformed requests targeting the ID parameter to detect exploitation attempts. 5) Employ Web Application Firewalls (WAFs) with custom rules to block SQL injection patterns targeting this endpoint. 6) Engage with the vendor or community to obtain patches or updated versions addressing this vulnerability. 7) Conduct regular security assessments and penetration tests focusing on injection flaws. 8) Educate development and operations teams about secure coding practices to prevent similar issues in future deployments.
