FKIE_CVE-2020-24054

Vulnerability from fkie_nvd - Published: 2020-08-21 15:15 - Updated: 2026-06-17 03:05
Severity
9.8 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
The administration console of the Moog EXO Series EXVF5C-2 and EXVP7C2-3 units features a 'statusbroadcast' command that can spawn a given process repeatedly at a certain time interval as 'root'. One of the limitations of this feature is that it only takes a path to a binary without arguments; however, this can be circumvented using special shell variables, such as '${IFS}'. As a result, an attacker can execute arbitrary commands as 'root' on the units.
