CVE-2026-25601 | Credential Exposure vulnerability in MEPIS RM

A vulnerability was identified in MEPIS RM, an industrial software product developed by Metronik. The application contained a hardcoded cryptographic key within the Mx.Web.ComponentModel.dll component. When the option to store domain passwords was enabled, this key was used to encrypt user passwords before storing them in the application’s database. An attacker with sufficient privileges to access the database could extract the encrypted passwords, decrypt them using the embedded key, and gain unauthorized access to the associated ICS/OT environment.

Base score Version Severity Vector Exploitability Impact Score source
6.4 3.1 MEDIUM
CVSS:3.1/AV:L/AC:H/PR:H/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:H)
Even with access, the exploit needs extra luck, timing, or a fussy environment to actually work.
Privileges required (PR:H)
They need powerful rights—admin, root, or similar—before this pays off.
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.
