CVE-2025-11030 is a medium-severity security vulnerability identified in the Tutorials-Website Employee Management System, specifically affecting the HTTP Request Handler component within the /admin/all-applied-leave.php file. The vulnerability arises due to improper authorization controls, allowing an unauthenticated remote attacker to potentially access or manipulate sensitive administrative functions related to employee leave management. The exact function impacted is unspecified, but the flaw enables unauthorized access without requiring any privileges or user interaction. The product follows a rolling release model, complicating version tracking and patch management. The CVSS 4.0 base score of 6.9 reflects a network-exploitable vulnerability with low complexity, no authentication required, and limited but non-negligible impact on confidentiality, integrity, and availability. Although no known exploits are currently active in the wild, the exploit code has been publicly disclosed, increasing the risk of exploitation. The vulnerability could allow attackers to view or alter employee leave records, potentially leading to data leakage, unauthorized modifications, or disruption of HR operations. Given the administrative nature of the affected functionality, the risk extends to insider threat facilitation or broader organizational impact if leveraged in multi-stage attacks.

For European organizations, this vulnerability poses a tangible risk to the confidentiality and integrity of employee data managed within the affected system. Unauthorized access to leave records could lead to privacy violations under GDPR, resulting in regulatory fines and reputational damage. Additionally, manipulation of leave data could disrupt workforce management, impacting operational continuity. Organizations relying on the Tutorials-Website Employee Management System for HR functions may face increased exposure to insider threats or external attackers exploiting this flaw as a foothold for lateral movement. The remote exploitability without authentication heightens the urgency for mitigation, especially in environments where the system is accessible from external networks or insufficiently segmented. The continuous delivery model of the product may delay timely patching, necessitating compensating controls. Overall, the vulnerability could undermine trust in HR data integrity and compliance, with potential cascading effects on organizational security posture.

1. Immediate network-level restrictions should be applied to limit access to the /admin/all-applied-leave.php endpoint, ideally restricting it to trusted internal IP addresses or VPN users only. 2. Implement strict web application firewall (WAF) rules to detect and block unauthorized access attempts targeting the vulnerable endpoint. 3. Conduct thorough access control reviews and harden authorization mechanisms within the Employee Management System, ensuring role-based access controls are correctly enforced. 4. Monitor logs for anomalous access patterns or repeated unauthorized requests to the affected URL. 5. Engage with the vendor or community to obtain patches or updates as soon as they become available, despite the rolling release model. 6. If patching is delayed, consider deploying application-layer proxies or reverse proxies that can enforce additional authentication or authorization checks. 7. Educate HR and IT staff about the vulnerability and encourage vigilance for suspicious activity related to employee leave data. 8. Regularly audit employee leave records for unauthorized changes to detect potential exploitation early.
