Lifecycle Timeline
6DescriptionCVE.org
A vulnerability, which was classified as problematic, has been found in 70mai M300 up to 20250611. This issue affects some unknown processing of the component HTTP Server. The manipulation leads to insufficiently protected credentials. The attack can only be done within the local network. The complexity of an attack is rather high. The exploitation is known to be difficult. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
AnalysisAI
Exposed root password via unauthenticated HTTP server in 70mai M300 dashcam firmware up to 20250611 allows local network attackers to obtain credentials. Public exploit code exists, but exploitation is difficult and requires local network access. No active exploitation in CISA KEV.
Technical ContextAI
The vulnerability resides in the HTTP server component of the 70mai M300 dashcam firmware. CWE-522 (Insufficiently Protected Credentials) indicates that the device stores or transmits credentials in a manner that can be accessed or decoded by an attacker. The CPE cpe:2.3:o:70mai:m300_firmware:*:*:*:*:*:*:*:* confirms the affected product is the firmware of the M300 model. The HTTP server likely exposes a root password without proper authentication or encryption, allowing anyone on the local network to retrieve it.
RemediationAI
No vendor-released patch identified at time of analysis. As a compensating control, restrict network access to the dashcam's HTTP server by placing it on a separate VLAN or disabling the HTTP server if possible. Block port 80/tcp on the device from untrusted networks. Note that disabling the HTTP server may affect legitimate functionality. Monitor for vendor updates.
