CVE-2025-14520 is a path traversal vulnerability identified in the baowzh hfly product up to commit 638ff9abe9078bc977c132b37acbe1900b63491c. The vulnerability exists in an unspecified function handling the /admin/index.php/datafile/delfile endpoint, where the filename argument is insufficiently sanitized. This allows an attacker to craft a filename parameter that traverses directories (e.g., using ../ sequences) to access or delete files outside the intended directory scope. The vulnerability can be exploited remotely without user interaction but requires low privileges (PR:L), indicating that the attacker must have some authenticated access, albeit minimal. The CVSS 4.0 score is 5.3 (medium), reflecting network attack vector, low complexity, no user interaction, and limited impact on confidentiality, integrity, and availability. The vendor follows a rolling release strategy but has not responded to the vulnerability disclosure, and no patches or mitigations have been published. Public exploit code is available, increasing the risk of exploitation despite no current reports of active attacks. The vulnerability could allow attackers to read or delete sensitive files, potentially leading to information disclosure or disruption of service. Organizations using baowzh hfly should assess exposure and implement compensating controls promptly.

For European organizations, this vulnerability poses a moderate risk primarily to confidentiality and integrity. Attackers with low-level access could exploit the path traversal to access sensitive configuration files, user data, or system files, potentially leading to data breaches or unauthorized data manipulation. Deletion of critical files could disrupt application availability or functionality. The lack of vendor response and patches increases the window of exposure. Organizations in sectors such as government, finance, healthcare, or critical infrastructure using baowzh hfly may face increased risk due to the sensitivity of their data and regulatory requirements like GDPR. Exploitation could result in compliance violations, reputational damage, and operational disruptions. The public availability of exploit code lowers the barrier for attackers, necessitating urgent mitigation. However, the requirement for low privileges limits exploitation to insiders or attackers who have already compromised user credentials or accounts with limited access.

1. Restrict access to the /admin/index.php/datafile/delfile endpoint to trusted administrators only, using network segmentation, IP whitelisting, or VPNs. 2. Implement strict input validation and sanitization on the filename parameter to reject any path traversal sequences such as '../'. 3. Employ web application firewalls (WAFs) with custom rules to detect and block path traversal attempts targeting this endpoint. 4. Monitor logs for unusual file access or deletion activities, especially around the vulnerable endpoint. 5. Enforce the principle of least privilege for user accounts to minimize the impact of compromised credentials. 6. If possible, isolate the application environment to limit file system access and prevent unauthorized file operations. 7. Engage with the vendor or community to track any forthcoming patches or updates and apply them promptly. 8. Consider alternative software solutions if the vendor remains unresponsive and the risk is unacceptable. 9. Conduct regular security audits and penetration tests focusing on file handling functionalities.
