Confidentiality: Low
Integrity: Low
Availability: Low

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

Attack Vector: Adjacent: The vulnerable component is bound to the network 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 physical (e.g., Bluetooth or IEEE 802.11) or logical (e.g., local IP subnet) network, or from within a secure or otherwise limited administrative domain (e.g., MPLS, secure VPN to an administrative network zone).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
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 impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 25 Jun 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-25.

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 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

1. Network Segmentation: Isolate EV charging stations on a dedicated network segment with strict access controls to limit exposure to network-adjacent attackers. 2. Disable or Restrict BLE Interfaces: If BLE functionality is not required for operational purposes, disable it entirely. If BLE is necessary, implement filtering or whitelisting to restrict which devices can communicate with the charging station. 3. Monitor BLE Traffic: Deploy BLE traffic monitoring tools to detect anomalous or unauthorized command injections targeting charging stations. 4. Firmware Updates: Engage with Autel to obtain patches or firmware updates addressing this vulnerability as soon as they become available. 5. Physical Security: Ensure charging stations are physically secured to prevent attackers from gaining close proximity required for BLE exploitation. 6. Incident Response Planning: Prepare response procedures for potential charging station compromise, including rapid isolation and forensic analysis. 7. Vendor Communication: Maintain active communication with Autel and industry groups to stay informed about vulnerability disclosures and mitigation strategies. 8. Access Control Policies: Implement strict access control policies for management interfaces of charging stations to prevent unauthorized configuration changes even if AT commands are injected.

Description

Autel MaxiCharger AC Wallbox Commercial ble_process_esp32_msg Misinterpretation of Input Vulnerability. This vulnerability allows network-adjacent attackers to inject arbitrary AT commands on affected installations of Autel MaxiCharger AC Wallbox Commercial charging stations. Authentication is not required to exploit this vulnerability. The specific flaw exists within the ble_process_esp32_msg function. The issue results from misinterpretation of input data. An attacker can leverage this vulnerability to execute AT commands in the context of the device. Was ZDI-CAN-26368.

Impact

For European organizations, the impact of this vulnerability can be significant, especially for entities operating fleets of electric vehicles or managing public and commercial EV charging infrastructure. Exploitation could allow attackers to disrupt charging services, potentially causing operational downtime and impacting business continuity. In critical infrastructure contexts, such as municipal or corporate EV charging stations, this could lead to reputational damage and customer dissatisfaction. Additionally, the ability to inject arbitrary AT commands may allow attackers to alter device configurations or firmware behavior, which could be leveraged for persistent access or lateral movement within an organization's network if the charging stations are connected to internal systems. Given the increasing adoption of EV infrastructure in Europe as part of green energy initiatives, this vulnerability poses a risk to the integrity and availability of charging services, which are becoming essential for transportation and logistics sectors. The lack of authentication and user interaction requirements lowers the barrier for exploitation, increasing the threat level for organizations with exposed or poorly segmented charging station networks.
