Arbitrary File Write in iobroker.admin

Critical severity GitHub Reviewed Published Sep 4, 2020 • Updated Oct 1, 2021

Package

npm iobroker.admin (npm)

Affected versions

< 3.6.12

Patched versions

3.6.12

Description

Versions of iobroker.admin prior to 3.6.12 are vulnerable to Path Traversal. The package fails to restrict access to folders outside of the intended folder in the /log/ route, 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 3.6.12 or later.
