CVE-2026-3179
A path traversal vulnerability was found in the FTP Backup on the ADM.
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.
