GCVE Workshop - 22 September 2026 (14:00-18:00), Luxembourg Before The Vulnopticon Conference - Registration

FKIE_CVE-2020-7240

Vulnerability from fkie_nvd - Published: 2020-01-20 20:15 - Updated: 2026-06-17 03:24
Severity
8.8 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
Meinberg Lantime M300 and M1000 devices allow attackers (with privileges to configure a device) to execute arbitrary OS commands by editing the /config/netconf.cmd script (aka Extended Network Configuration). Note: According to the description, the vulnerability requires a fully authenticated super-user account using a webUI function that allows super users to edit a script supposed to execute OS commands. The given weakness enumeration (CWE-78) is not applicable in this case as it refers to abusing functions/input fields not supposed to be accepting OS commands by using 'Special Elements.
