CVE-2018-25144 | Microhard Systems IPn4G 1.1.0 Arbitrary File Access via Undocumented System Editor

Exp

Microhard Systems IPn4G 1.1.0 contains an authentication bypass vulnerability in the hidden system-editor.sh script that allows authenticated attackers to read, modify, or delete arbitrary files. Attackers can exploit unsanitized 'path', 'savefile', 'edit', and 'delfile' parameters to perform unauthorized file system modifications through GET and POST requests.

8.4 3.1 HIGH
CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H Click to expand
Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
