CVE-2025-5617 is a SQL Injection vulnerability identified in version 1.2 of the PHPGurukul Online Fire Reporting System, specifically within the /admin/manage-teams.php file. The vulnerability arises from improper sanitization or validation of the 'teamid' parameter, which is susceptible to malicious SQL payloads. An attacker can remotely exploit this flaw without authentication or user interaction, by manipulating the 'teamid' argument to inject arbitrary SQL commands. This can lead to unauthorized access to the backend database, allowing attackers to read, modify, or delete sensitive data, potentially compromising the confidentiality, integrity, and availability of the system. The vulnerability has been publicly disclosed, although no known exploits have been observed in the wild to date. The CVSS 4.0 base score is 5.3, indicating a medium severity level, reflecting the ease of remote exploitation but limited impact scope and privileges required (low privileges). The vulnerability does not require user interaction and affects a critical administrative interface, which could be leveraged for further privilege escalation or lateral movement within the affected environment.

For European organizations using the PHPGurukul Online Fire Reporting System 1.2, this vulnerability poses a significant risk to operational continuity and data security. Fire reporting systems are critical infrastructure components that handle sensitive emergency response data. Exploitation could result in unauthorized disclosure of sensitive information, manipulation of team assignments, or disruption of emergency response workflows. This could undermine public safety efforts and damage organizational reputation. Additionally, compromised systems could be used as pivot points for broader network intrusions. Given the administrative nature of the affected endpoint, attackers might gain elevated access, increasing the risk of data breaches or service outages. The medium severity rating suggests that while the vulnerability is exploitable remotely, the impact might be contained if proper network segmentation and monitoring are in place. However, the critical nature of fire reporting systems elevates the practical impact beyond the CVSS score alone.

1. Immediate application of patches or updates from PHPGurukul once available is the primary mitigation step. Since no patch links are currently provided, organizations should monitor vendor communications closely. 2. Implement strict input validation and parameterized queries or prepared statements in the affected codebase to prevent SQL injection. 3. Restrict access to the /admin/manage-teams.php endpoint using network-level controls such as VPNs, IP whitelisting, or firewall rules to limit exposure to trusted administrators only. 4. Employ Web Application Firewalls (WAFs) with SQL injection detection rules to block malicious payloads targeting the 'teamid' parameter. 5. Conduct thorough logging and monitoring of administrative actions and anomalous database queries to detect potential exploitation attempts early. 6. Perform regular security assessments and code reviews focusing on input handling in administrative modules. 7. Educate system administrators about the risks and signs of SQL injection attacks to enhance incident response readiness.
