CVE-2024-3767 is a SQL Injection vulnerability identified in PHPGurukul News Portal version 4.1, specifically within the /admin/edit-post.php file. The vulnerability arises from improper sanitization or validation of the 'posttitle' or 'category' parameters, which are user-controllable inputs. An attacker can remotely manipulate these parameters to inject malicious SQL code, potentially allowing unauthorized access or modification of the backend database. The vulnerability does not require user interaction but does require low privileges (PR:L) and no authentication (AT:N), meaning an attacker with limited access could exploit it remotely without needing to authenticate. The CVSS 4.0 base score is 5.3, categorized as medium severity, reflecting limited confidentiality, integrity, and availability impacts (VC:L, VI:L, VA:L). The scope is unchanged (S:N), and no user interaction is needed (UI:N). Although no known exploits are currently in the wild, the vulnerability has been publicly disclosed, increasing the risk of exploitation. The lack of available patches or mitigations from the vendor at this time further elevates the threat. SQL Injection vulnerabilities can lead to data leakage, unauthorized data manipulation, or even full database compromise, depending on the database permissions and the attacker's skill. Given that this affects an administrative interface, successful exploitation could allow attackers to alter news posts or gain further access to the system.

For European organizations using PHPGurukul News Portal 4.1, this vulnerability poses a significant risk to the confidentiality and integrity of their news content and potentially sensitive backend data. News portals often contain sensitive editorial content and user data, and unauthorized modification could damage organizational reputation and trust. Additionally, attackers could leverage this vulnerability as a foothold for further lateral movement within the network, potentially compromising other systems. The fact that the vulnerability is remotely exploitable without authentication increases the attack surface, especially for organizations with publicly accessible administrative interfaces. Given the medium CVSS score, the direct impact might be limited if database permissions are properly restricted; however, the risk of data leakage or defacement remains. European organizations in sectors such as media, education, and public information dissemination that rely on PHPGurukul News Portal could face operational disruptions and reputational harm if exploited.

1. Immediate mitigation should include restricting access to the /admin/edit-post.php interface via network controls such as IP whitelisting or VPN-only access to reduce exposure. 2. Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the 'posttitle' and 'category' parameters. 3. Conduct a thorough code review and apply input validation and parameterized queries or prepared statements to sanitize user inputs in the affected file. 4. If possible, upgrade to a patched version once released by the vendor or apply community-supplied patches after thorough testing. 5. Monitor logs for suspicious activities related to SQL injection attempts and unusual database queries. 6. Educate administrators on the risks of exposing administrative interfaces publicly and enforce strong authentication and access controls. 7. Consider isolating the news portal database with least privilege principles to limit the impact of potential exploitation.
