CVE-2021-40661

Exp

A remote, unauthenticated, directory traversal vulnerability was identified within the web interface used by IND780 Advanced Weighing Terminals Build 8.0.07 March 19, 2018 (SS Label 'IND780_8.0.07'), Version 7.2.10 June 18, 2012 (SS Label 'IND780_7.2.10'). It was possible to traverse the folders of the affected host by providing a traversal path to the 'webpage' parameter in AutoCE.ini This could allow a remote unauthenticated adversary to access additional files on the affected system. This could also allow the adversary to perform further enumeration against the affected host to identify the versions of the systems in use, in order to launch further attacks in future.

Base score Version Severity Vector Exploitability Impact Score source
7.5 3.1 HIGH
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N Click to expand
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.
