CVE-2020-24054
As a result, an attacker can execute arbitrary commands as 'root' on the units.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.55%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
