AI-suggested
To mitigate CVE-2026-3179, organizations should immediately verify if their ASUSTOR ADM installations fall within the affected version ranges (4.1.0 to 4.3.3.ROF1 and 5.0.0 to 5.1.2.RE51). If patches or updates are released by ASUSTOR, they should be applied without delay. In the absence of official patches, organizations should consider disabling the FTP Backup feature or restricting FTP backup operations to trusted, internal FTP servers only, eliminating exposure to malicious or MITM FTP servers. Network segmentation and firewall rules should be employed to limit FTP traffic to known safe sources. Additionally, monitoring file system changes and backup directories for unexpected modifications can help detect exploitation attempts. Employing secure FTP alternatives (e.g., SFTP or FTPS) with strong authentication and encryption can reduce the risk of MITM attacks. Finally, organizations should conduct regular security audits and maintain up-to-date backups stored offline or in immutable storage to recover from potential compromises.
Description
The FTP Backup on the ADM does not properly sanitize filenames received from the FTP server when parsing directory listings. A malicious server or MITM attacker can craft filenames containing path traversal sequences, causing the client to write files outside the intended backup directory. A path traversal vulnerability may allow an attacker to overwrite arbitrary files on the system and potentially achieve privilege escalation or remote code execution. Affected products and versions include: from ADM 4.1.0 through ADM 4.3.3.ROF1 as well as from ADM 5.0.0 through ADM 5.1.2.RE51.
