CVE-2018-25145 — Microhard Systems IPn4G 1.1.0 Configuration Disclosure via Authenticated Download

Microhard Systems IPn4G 1.1.0 contains a configuration file disclosure vulnerability that allows authenticated attackers to download sensitive system configuration files. Attackers can retrieve configuration files from multiple directories including '/www', '/etc/m_cli/', and '/tmp' to access system passwords and network settings.

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

EPSS 0.5% (30-day exploitation probability)+6
Technical severity (medium)+3
CISA SSVC: exploitation "poc"+5

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Exploitation

Not confirmed

Not in CISA KEV — an absence of record, not proof it is unexploited.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

Identify exposed assets running the affected vendor/product/version combinations (Microhard Systems Microhard Systems 3G/4G Cellular Ethernet and Serial Gateway Configuration Download, Microhardcorp Bullet-3g Firmware, Microhardcorp Bullet-lte Firmware…).
No fix documented in the sources: reduce exposure and monitor the vendor advisory.
Search available logs for exploit probes matching the vulnerability class (access control), errors and authentication anomalies.
