Last modified

CVE-2026-3179 is a critical-severity vulnerability rated 9.2/10 on the CVSS scale. 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. EPSS estimates a 0.49% chance of exploitation in the next 30 days.

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.
