CVE-2025-67315 identifies a Cross Site Request Forgery vulnerability in the Employee Leave Management System version 2.1, targeting the manage-employee.php component. CSRF vulnerabilities enable attackers to perform unauthorized actions on behalf of authenticated users by exploiting the trust a web application places in the user's browser. In this case, the attacker can escalate privileges remotely by crafting malicious requests that, when executed by an authenticated user, modify employee management data or permissions without the user's consent. The vulnerability arises due to the absence or improper implementation of anti-CSRF protections such as tokens or referer validation in the affected component. Although no specific affected versions are listed beyond version 2.1, the vulnerability's presence in a critical HR management module suggests a significant risk to data integrity and confidentiality. No CVSS score is currently assigned, and no public exploits have been reported, indicating the vulnerability is newly disclosed and may not yet be actively exploited. However, the potential for privilege escalation and unauthorized data manipulation makes this a critical concern for organizations relying on this system for employee leave and management functions.

The primary impact of CVE-2025-67315 is unauthorized privilege escalation within the Employee Leave Management System, potentially allowing attackers to alter employee records, leave balances, or permissions. For European organizations, this could lead to breaches of sensitive personal data protected under GDPR, resulting in legal and financial repercussions. The integrity of HR data could be compromised, affecting payroll, compliance reporting, and operational decision-making. Availability impact is likely limited but could occur if attackers disrupt employee management processes. The ease of exploitation via CSRF means attackers only need to trick authenticated users into visiting malicious sites or clicking crafted links, increasing the risk of widespread abuse. Organizations with large or distributed workforces, or those in regulated sectors such as finance, healthcare, or government, face heightened risks due to the critical nature of accurate employee data and strict compliance requirements.

To mitigate CVE-2025-67315, organizations should immediately implement anti-CSRF protections in the Employee Leave Management System, including the use of synchronizer tokens or double-submit cookies in all state-changing requests, especially in manage-employee.php. Enforce strict session management policies, such as short session timeouts and re-authentication for sensitive actions. Conduct thorough code reviews and penetration testing focused on CSRF and privilege escalation vectors. Educate users about phishing and social engineering risks to reduce the likelihood of successful CSRF attacks. Monitor logs for unusual activity related to employee management functions and implement anomaly detection to identify potential exploitation attempts. If possible, apply vendor patches or updates once available, and consider isolating the HR management system behind additional access controls or network segmentation to limit exposure.
