CVE-2025-4880 is a SQL Injection vulnerability identified in PHPGurukul News Portal version 4.1, specifically affecting the /admin/aboutus.php file. The vulnerability arises from improper sanitization or validation of the 'pagetitle' parameter, which can be manipulated by an attacker to inject malicious SQL queries. This flaw allows an unauthenticated remote attacker to execute arbitrary SQL commands on the backend database without requiring any user interaction or privileges. The vulnerability is classified as medium severity with a CVSS 4.0 base score of 6.9, reflecting the ease of exploitation (network attack vector, no authentication or user interaction needed) and the potential impact on confidentiality, integrity, and availability, albeit with limited scope and impact. Exploiting this vulnerability could enable attackers to extract sensitive data, modify or delete database records, or potentially escalate privileges within the application. Although no public exploits are currently known to be actively used in the wild, the disclosure of the vulnerability increases the risk of exploitation. The lack of available patches or official mitigation guidance from the vendor further elevates the urgency for organizations using this software to implement protective measures.

For European organizations using PHPGurukul News Portal 4.1, this vulnerability poses a significant risk to the confidentiality and integrity of their data. News portals often contain sensitive editorial content, user information, and administrative data, which if compromised, could lead to reputational damage, data breaches, and regulatory non-compliance under GDPR. Attackers exploiting this vulnerability could manipulate news content, disrupt service availability, or gain unauthorized access to backend systems. Given the remote and unauthenticated nature of the attack, the threat surface is broad, potentially affecting multiple organizations simultaneously. The impact is particularly critical for media companies, government-affiliated news agencies, and other entities relying on this software for public communication. Additionally, compromised news portals could be leveraged as vectors for misinformation or further attacks targeting European audiences.

Since no official patches are currently available, European organizations should prioritize immediate risk reduction strategies. These include: 1) Implementing Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the 'pagetitle' parameter in /admin/aboutus.php; 2) Applying strict input validation and sanitization at the application level, if source code access is available, to neutralize malicious payloads; 3) Restricting access to the /admin directory using IP whitelisting, VPNs, or strong authentication mechanisms to reduce exposure; 4) Monitoring logs for unusual database queries or access patterns indicative of exploitation attempts; 5) Conducting thorough security assessments and penetration testing focused on SQL injection vectors; and 6) Planning for an upgrade or migration to a patched or alternative news portal solution once available. Organizations should also ensure regular backups of the database and application to enable rapid recovery in case of compromise.
