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. |

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.
