A05:2021 - Security Misconfiguration
ASVS 5.0
V15 - Secure Coding and Architecture Resource release
Exploitation Conditions

Requires local network access to the dashcam (AV:A) and low privileges (PR:L). The attack complexity is high (AC:H). The Telnet service must be enabled and the demo.sh script accessible. No user interaction needed (UI:N).

Impact

CVSS 4.0 base score 5.0 (Medium) with vector AV:A/AC:H/PR:L/UI:N/VA:H indicates local network access, high complexity, low privileges required, and high availability impact. EPSS score 0.06% (low probability) suggests exploitation is not widespread. No KEV listing. Public exploit exists but difficulty is high. Overall risk is low due to high complexity and local network requirement.

Exploit ScenarioDerived

An attacker on the same local network as the dashcam sends a crafted request to the Telnet service's demo.sh script, causing the device to crash. Public exploit code is available, but the attack requires high complexity and local network access.

This Month Plan within 30 days. Why: MEDIUM severity (CVSS 4.0-6.9).

AnalysisAIv2 – Jul 26, 2026

Denial of service in 70mai M300 dashcam firmware up to 20250611 allows an attacker on the local network to crash the device via the Telnet service's demo.sh script. A public exploit exists, but exploitation requires local network access and high attack complexity. No active exploitation in CISA KEV.

RemediationAI

No vendor patch available as vendor did not respond. Compensating controls: disable Telnet service if not needed, restrict network access to the dashcam (e.g., VLAN segmentation, firewall rules blocking Telnet port 23), or upgrade to a newer firmware version if released. Disabling Telnet may affect remote management functionality.
