Arbitrary File Write in iobroker.js-controller

Description

Versions of iobroker.controller prior to 2.0.25 are vulnerable to Path Traversal. The package fails to restrict access to folders outside of the intended /adapter/<adapter-name> folder, which may allow attackers to include arbitrary files in the system. An attacker would need to be authenticated to perform the attack but the package has authentication disabled by default.

Recommendation

Upgrade to version 2.0.25 or later.

Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
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:N)
Data isn’t meaningfully altered or forged.
Availability (A:N)
Service keeps running; no real outage angle.
