Threat metrics

Exploit Maturity: POC

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Adjacent: The vulnerable system is bound to a protocol stack, but the attack is limited at the protocol level to a logically adjacent topology. This can mean an attack must be launched from the same shared proximity (e.g., Bluetooth, NFC, or IEEE 802.11) or logical network (e.g., local IP subnet), or from within a secure or otherwise limited administrative domain (e.g., MPLS, secure VPN within an administrative network zone).
Attack Complexity: High: The successful attack depends on the evasion or circumvention of security-enhancing techniques in place that would otherwise hinder the attack. These include: Evasion of exploit mitigation techniques, for example, circumvention of address space randomization (ASLR) or data execution prevention (DEP) must be performed for the attack to be successful; Obtaining target-specific secrets. The attacker must gather some target-specific secret before the attack can be successful. A secret is any piece of information that cannot be obtained through any amount of reconnaissance. To obtain the secret the attacker must perform additional attacks or break otherwise secure measures (e.g. knowledge of a secret key may be needed to break a crypto channel). This operation must be performed for each attacked target.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the Vulnerable System.
Vulnerable system integrity: None: There is no loss of integrity within the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.
Exploit Maturity: POC: Based on threat intelligence sources each of the following must apply: · Proof-of-concept is publicly available · No knowledge of reported attempts to exploit this vulnerability · No knowledge of publicly available solutions used to simplify attempts to exploit the vulnerability

Exploitation evidence

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), CVSS vector, the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Network Segmentation: Isolate 70mai M300 devices on dedicated VLANs or network segments with strict access controls to prevent unauthorized local network access.
Access Control Enforcement: Restrict access to the dashcam’s web server interface to trusted administrators only, using MAC filtering or IP whitelisting where possible.
Disable Unnecessary Services: If feasible, disable the web server or remote management features on the device to reduce the attack surface.
Monitor Network Traffic: Implement network monitoring to detect unusual access patterns or attempts to connect to the dashcam’s web interface.
Physical Security: Ensure devices are physically secured to prevent attackers from connecting directly to the local network or device interfaces.
Vendor Engagement: Continue to monitor for vendor updates or patches, and consider alternative devices if the vendor remains unresponsive.
Incident Response Preparedness: Develop procedures to quickly isolate affected devices if suspicious activity is detected. These steps go beyond generic advice by focusing on network architecture and operational controls tailored to the device’s deployment context.

Description

A vulnerability, which was classified as problematic, was found in 70mai M300 up to 20250611. Affected is an unknown function of the component Web Server. The manipulation leads to improper access controls. The attack can only be initiated within the local network. The complexity of an attack is rather high. The exploitability is told 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.

Impact

For European organizations, the direct impact of CVE-2025-6527 is relatively low due to the limited scope and low severity of the vulnerability. However, organizations that deploy 70mai M300 dashcams in fleet vehicles or corporate environments could face localized risks if attackers gain access to the internal network segment where these devices operate. Potential impacts include unauthorized configuration changes or limited data exposure from the dashcam, which could affect operational monitoring or vehicle security. While the vulnerability does not directly compromise core IT systems, it could serve as a foothold for lateral movement within segmented networks if combined with other vulnerabilities or weak network segmentation. The lack of vendor patching means organizations must rely on compensating controls. Given the high attack complexity and local network requirement, the threat is less critical for organizations with strong network segmentation and access controls. However, organizations with less mature network security or extensive use of these devices in sensitive environments should consider the risk more seriously.
