Attack Complexity: Low

Confidentiality: Low
Integrity: None
Availability: None

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

Attack Vector: Physical: The attack requires the attacker to physically touch or manipulate the vulnerable component. Physical interaction may be brief or persistent.
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: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
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: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

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 30 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.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), 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

To mitigate CVE-2025-27769, organizations should implement strict physical security controls around Siemens Heliox EV charging stations to prevent unauthorized physical access to the charging cables. Deploying surveillance, access barriers, or secure enclosures can reduce the risk of exploitation. Siemens customers should monitor official communications for firmware updates addressing this vulnerability and apply patches promptly once available. Network segmentation of EV charging infrastructure can limit the exposure of internal services even if the communication channel is accessed. Additionally, organizations can conduct regular security assessments of their EV charging stations to detect unauthorized access attempts. Implementing logging and alerting mechanisms on the charging stations or associated management systems can help identify suspicious activities. Finally, educating staff and users about the risks of physical tampering with charging stations can enhance overall security posture.

Description

A vulnerability has been identified in Heliox Flex 180 kW EV Charging Station (All versions < F4.11.1), Heliox Mobile DC 40 kW EV Charging Station (All versions < L4.10.1). Affected devices contain improper access control that could allow an attacker to reach unauthorized services via the charging cable.

Impact

The primary impact of this vulnerability is the potential unauthorized access to internal services of Siemens EV charging stations, which could lead to information disclosure. While the confidentiality impact is low, exposure of sensitive operational data or configuration details could aid attackers in further attacks or reconnaissance. The lack of impact on integrity and availability means the charging stations' core functionality remains intact, reducing the risk of service disruption. However, given the growing deployment of EV infrastructure worldwide, any compromise of charging stations could undermine user trust and operational security. Organizations operating Siemens Heliox charging stations may face increased risk if attackers gain physical access to the charging cables, especially in public or semi-public locations. The vulnerability could also have regulatory implications if sensitive data is exposed. Overall, the threat is limited by the need for physical access and the low severity, but it should not be ignored due to the critical role of EV charging infrastructure in energy and transportation sectors.
